SUMMARY

Upon the request of Frontier Pacific Mining Corporation (the “Company”) this

qualifying report has been made on the San Francisco property (the “Property”),

Yécora Mining District, Sonora, México. It incorporates a summary of previous

work, an appraisal of the exploration potential of the Property and makes

recommendations for further work. This qualifying report is based on a compilation

of published and unpublished assessment reports and field examinations by the

authors, one of who is a “qualified person” within the meaning of National

Instrument 43-101 of the Canadian Securities Administrators.

The San Francisco property comprises five government mineral concessions,

totaling 1,287 hectares, located 9 kilometers east of Yécora, in the southeastern

part of the state of Sonora. The concessions have been registered under the

names of Minera Holmex, S.A. de C.V. and Manuel Alberto Weber Ramirez, and

have been optioned to Frontier Pacific Mining Corporation. The Property, which is

near Yécora, is situated approximately 290 kilometers east of Hermosillo, near the

Chihuahua State border. Access is by the main, Hermosillo-to-Chihuahua highway

for 15 kilometers east of Yécora, and then south for 2 kilometers via un-maintained

dirt road. The Property is in a pleasant, forested area at an elevation of 1600

meters, whose climate is favorable for year-round mining, and a trained, mining-

industrial workforce is available in the area.

The San Francisco Property is situated within the Sierra Madre Occidental (“SMO”)

geologic-physiographic province, which is host to many world-class Tertiary volcanic-

related precious metal mines and deposits, such as the Tayoltita and Mulatos mines,

and the Ocampo, Dolores, El Sauzal, Moris Mine, and Pinos Altos deposits.

The mining history of the San Francisco area is poorly documented, and no

production records have been found. The San Francisco open pit mine may have

been the first developed mine in this region, reportedly in 1873, having a 30-meter

shaft sunk on the high-grade main gold zone. A decline and adits were developed at

ii

the nearby Lupe Alma mine to the south, but the dates of development are not

known. High-grade gold ore reportedly was developed at the California Vein system

in the southern part of the Property. The fairly extensive mine workings at Los

Cumbres, Nueva York, and Santo Niño were developed on a small scale prior to

1940 for high-grade gold and Cu-Pb-Ag-Zn veins, and by slightly larger-scale, tank

flotation and leach operations prior to 1988. A limited exploration drilling program

was conducted in the mid-1990s, and perhaps earlier, in the San Francisco area.

The other companies who worked in this area drilled at least eight holes, mostly

shallow, on the Property. No holes have been drilled to intersect the vein systems at

depths of more than 200 feet below the surface. Limited gold mine production is

presently taking place at the Mina Santo Niño, east of the Property. No Mineral

Reserves were blocked out by any of the previous lessee parties. Some high-grade

gold drill intercepts were encountered at the San Francisco Mine.

The regional and local geology at San Francisco consists principally of Tertiary-age

rocks of volcanic origin, belonging to 1) the Lower Volcanic Series (“LVS”),

principally andesitic strata, dikes, and breccia bodies, and 2) to the overlying Upper

Volcanic Series (“UVS”), principally dacitic to rhyolitic strata, and dikes. No

Mesozoic or Paleozoic basement rocks are exposed on the San Francisco

property. Mineralized granitic dikes and a pluton are exposed in the Nueva York -

California area. These intrusives cut the LVS andesitic strata. Surficial alluvium

and colluvium cover parts of the Property area. The depth to basement below the

SMO volcanics is not known.

Structurally, the San Francisco area is broken by numerous N- to NW, WNW- and

NE-trending, high-angle normal faults. WNW-trending fracture zones and airphoto

lineaments suggest that a circular caldera system could have been present just south

of the Property. Certain of the later(?) NW and NNW fractures may have been

related to radial fractures off from the circular features, and some certainly are related

to later Basin and Range – type extension. Alteration consists of propylitization,

argillization, silicification, and the alteration and mineralization appear to be controlled

iii

by these structures. The higher-grade gold-silver mineralization occurs in epithermal

veins of mid-Tertiary age, associated with late-phase silicification and sulfides,

predominately pyritic. Base metal and silver sulfides are present in high-grade vein

exposures in the San Francisco open cut area. Oxidation of the sulfides is limited, as

fresh sulfides usually are present within a few meters of the surface.

The main exploration targets on the Property are low-sulfidation Epithermal-Type

volcanic-hosted, quartz-gold-(pyrite) vein systems, and breccia bodies in UVS rocks,

in an area of approximately 4 km2. The vein systems have three primary

orientations: NNW, NE, and WNW. The former two vein systems have steep to

vertical dips, and the WNW-trending veins have steep dips. The individual vein

systems were typically 2 to possibly 8 meters thick, with individual vein segments up

to 1 kilometer in length.

Significant gold assays were returned from the sampling conducted on the

Property area. The vein systems are exposed vertically over less than 150 meters

of elevation, with the best gold-silver grades shown at the lowest exposed levels.

The base elevation of the gold-silver system is not known in the Yécora region or

the Property area, but if it is similar to the nearby Ocampo mining district, it may

have a total vertical ore system extent of 700 meters.

It is recommended herein that Frontier Pacific Mining Corporation conduct a Phase

1 program consisting of geologic mapping, sampling, and excavatory trenching, to

define the surface extent and grade of gold-silver mineralization. Contingent upon

the receipt of favorable results from this program, it is recommended that the

Company then continue on and proceed with a Phase 2 program, consisting of a

drill program on the prioritized targets, of two 150-meter diamond core drillholes to

test strategic targets in gold-silver vein systems on the Property.

1.0 INTRODUCTION

Upon the request of Frontier Pacific Mining Corporation (the “Company”), an

evaluation and this qualifying report have been made on the San Francisco property

(the “Property”), Yécora Mining District, Sonora, México, to summarize previous work,

appraise the exploration potential of the Property, and make recommendations for

future work.

This report is based on company property evaluation reports, a compilation of

published and unpublished data, maps, and reports made by persons cited below,

and field examinations of the Property and nearby and mines in the region made by

the writers over the last several years. The senior writer examined the Property

most recently on April 20, 2000, and the junior writer surface sampling on the

Property in the fall of 2000 on behalf of Barrick Gold Corporation.

Limited mining for gold and silver was conducted on the Property in the San

Francisco mine area, perhaps as early as 1873. An open cut was excavated and

mining on the Colón vein system took place. The Property vendor and his family

also conducted limited small-scale mining in 1990 in this area.

The last substantial work conducted on the Property was by Pacific Rainier de

México, who in 1995 conducted sampling, geological mapping, and drilled 8 holes on

the Colón vein system in the San Francisco open cut. Other companies, which

worked on the Property include Minera Car, S.A., who may have drilled 3 holes in

1984 on the Colón vein system (Rodríguez S., 1995). Compañia Minera Junipero,

S.A. de C.V., Sierra Nevada Gold, Phelps Dodge, and Barrick also conducted

examinations of the Property.

A property description is given in metric units and terms of reference. These data

are discussed and interpreted, and recommendations are made for further work.

2.0 DISCLAIMER

The writers did not have written descriptions of the sampling and quality-

assurance, quality control (“QA/QC”) procedures followed by previous lessees, nor

has he examined any drill cuttings or cores, nor all of the original assay data sheets

from the Property. These data were not available to the writers at the time of

writing of this qualifying report.

Much of the information known about the early work at the San Francisco mine

was derived from personal conversations with the property vendor, Mr. Alberto

Weber Ramirez, and is not published or elsewhere publicly available. Thus, any

conclusions made about historical work on the San Francisco and California mines

on the Property and its gold-silver mineralization should be framed within this

context, and the fact that such gold mining is reported to have occurred on theProperty is not necessarily indicative of any mineralization which may bepresent on the Property that is the subject of this technical report.

Some of the opinions expressed in this report were from other persons known by

the writers, and do not necessarily represent the opinions of the writers.

3.0 LOCATION, ACCESS, and PHYSIOGRAPHY

The San Francisco Property is situated approximately 290 kilometers east of

Hermosillo, near the Chihuahua State border. Access is by the main, Hermosillo-

to-Chihuahua Highway 16 for 15 kilometers east of Yécora, a logging town and the

regional population center with about 5,100 people, and then south for 2 kilometers

via un-maintained dirt road. Passable dirt roads traverse most of the Property area

(Figures 1, 2).

Minor supplies are available at Yécora. The capital city Hermosillo has all needed

equipment, supplies and services available for mining companies to carry out full

sequence exploration and mining development projects. The people in the area are

friendly, with no local conflicts noted.

The Property is in relatively flat to hilly plateau terrain, with elevations between 1,500

meters on certain valley floors to 1850 meters on the highest hilltop in the southern

part of the Property. The main Colón vein system at the San Francisco Mine (Figure

3) is exposed at elevations of 1620 to 1700 meters. The mesa-like nature of much

of the topography would give a mine operator wide latitude in the siting/placement

of minesite, tailings, or heap leach facilities.

The Property has a moderate cover of pine trees, oaks, and shrubs, typical of the

Sierra Madre Occidental at these elevations. The temperatures are moderate year-

round, being cool during the winter, with occasional light snowfalls, and are warm

during the summer with cool nights. Strong rains occur only occasionally during the

summer rainy season, and exploration and mining may be conducted year-round.

The Property has not had reported water shortages, but no aquifer testing has been

done to date. A trained mining-industrial workforce is available in the area.

4.0 PROPERTY DESCRIPTION AND STATUS

The San Francisco Property area comprises 5 exploration concessions, totaling

1,287 hectares, granted by the owner, the Mexican federal government, as listed in

Table 1. The mineral zones and exploration concessions (Figure 4) are located in the

Yécora 1:50,000 map sheet area (INEGI Map H12D77), near latitude 28° 21' N and

longitude 108° 50' W (UTM coordinates 3,137,000 North and 713,000 East, Zone

12R), Municipality of Yécora, Yécora Mining District, Sonora, México.

The concessions form two groups, also outlined in Figures 7 and 9, separated by

approximately 1 kilometer, north south. The concessions within each group are

contiguous with each other. Private ranchers, with whom Mr. Weber Ramirez has

good relations, own the surface estate of the Property, at least in part. In 1995 an

“ejido” ( a community land ownership collective) appears to have existed covering the

Property, as a previous lessee of the Property, Pacific Rainier de México, received a

notice of authorization to conduct exploration from the Comisario then in charge of an

ejido based in Yécora, Mr. Gilberto Valenzuela Molina. There are no apparent legal

conflicts pertaining to the mineral concessions, whose titles were checked by

Engineer David Rosales Esquivel, a registered mineral surveyor. No aquifer testing

or environmental baseline studies have been conducted on the Property.

Frontier Pacific Mining Corporation, a Canadian corporation whose domicile is 100-

853 Richards Street, 3rd Floor, Vancouver, B.C., V6B 3B4, controls a 4-year

exploration contract with option to purchase the San Francisco, Maguarichi, and

Martha 2 concessions from Manuel Alberto Weber Ramirez, a citizen of México

whose domicile is Calle Ignacio De La Llave 8806, Colónia Los Pinos, Chihuahua,

Chihuahua 31416, México. The Company also controls the La Estrella and Chuchu

concessions via lease-option to purchase from Minera Holmex, S.A. de C.V. These

concessions control all of the known mineral systems on the Property.

5

The sixth concession listed in Table 1 is the La Esperanza V Fracción 2, whose

owner of record has been Pacific Rainier De México, S.A. de C.V. This small

concession, which has expired but has not been declared free by the government, is

located within the boundaries of the San Francisco concession, south of the Colón

gold-silver vein system. No veins are reported to occur on this concession, but

neither the writers nor their associates have verified this in the field.

The concessions listed in Table 1, with the exception of the La Esperanza V Fracción

2, have been acquired by Frontier Pacific Mining Corporation from Minera Holmex,

S.A. de C.V. under an Assignment Agreement between the parties dated May 20,

2002, in consideration of a “Finders Fee Agreement, Mexican Property, San

Francisco” between the Company and International American Resources Inc. (“IAR”)

6

dated February 28, 2002. Minera Holmex, S.A. de C.V. (“Holmex”) owned by the

principal of International American Resources Inc., staked the La Estrella and

Chuchu concessions, and acquired the Maguarichi, San Francisco and Martha 2

concessions from Manuel Alberto Weber Ramirez and Martha Azucena Holguin

Lopez (“Weber”), under an “Exploration Contract With Option To Purchase” dated

May 3, 2002. The writers know of no other agreements, other encumbrances or

environmental liabilities that are attached to the Property. The property has been fully

surveyed in accordance with Mexican law, by a registered mineral surveyor.

The agreement between Weber and Holmex stipulates a total purchase price of

US$650,000, with $240,000 to be paid in variable, semi-annual installments over 48

months, and a final payment of $410,000 to be made within the twenty days

following. Weber would reserve a 1.5 percent “net production royalty” from the

Property and all concession areas later staked during the term of the agreement

within a 5-kilometer distance around the Maguarichi to Martha 2 claim areas. This

royalty may be purchased for US$1,500,000 or $500,000 per each 0.5 percent. The

agreement also stipulates work commitments of $25,000 to be spent on work on the

Property during each of the first and second six months that the agreement is in

force; $75,000 to be spent during the 2nd year; $100,000 during the 3rd year; and

$100,000 during the 4th year. In addition, the agreement stipulates that Weber may

conduct mine production from veins on the Property in an amount up to 2,400 tonnes

per year, prior to the exercise of the option to purchase by Holmex. Weber also was

granted a preference right to enable its staking of the adjacent Balila and Ampliación

Santo Niño areas, which have not yet been opened up for staking by the government.

The agreement between IAR and Frontier Pacific Mining Corporation stipulates a

payment of US$10,000.00 by the Company upon assignment of the Holmex-Weber

agreement to the Company, and that the Company is obligated to pay for 7 days of

consulting work per month at a rate of US$400.00 per day to IAR’s associates. In the

absence of work, the Company may pay IAR US$9,000.00 each half year until the

option to purchase the Property is exercised or the contract is terminated by Frontier

7

Pacific Mining Corporation. During the term of the contract, the Company is

obligated to pay IAR an amount equal to ten percent (10%) of all exploration

expenditures up to CAD$300,000.00, 7.5% of expenditures between

CAD$300,000.00 and CAD$1,000,000.00, and 5% 0f expenditures greater than

CAD$1,000,000.00, to be paid to IAR in cash or in the shares of Frontier Pacific

Corporation publicly-traded stock. The Company is obligated to pay IAR an amount

equal to US$100,000.00 at the start of production or when the option to purchase the

Property is exercised by the Company.

The Company is obligated to pay all past due and future concession holding fees, all

work obligations stipulated by federal law, Mr. Weber’s costs which were incurred in

the staking and filing of the Martha 2 concession, and to maintain all property rights

which were in existence at the date of signing of the agreements.

Frontier Pacific Mining Corporation must comply with Mexican environmental

regulations in the pursuit of its exploration of the Property. It likely must get

permission from the Mexican environmental agency “SEMARNAT” office in

Hermosillo prior to conducting “significant” surface disturbance, such as trenching,

drilling, or construction of new roads. An appraisal of these obligations should be

made through a Mexican environmental consultant prior to conducting such

disturbances. No permits are needed to conduct sampling and mapping.

5.0 AREA MINING HISTORY AND PRODUCTION

The writers were not able to find many published details of the mining history of the

San Francisco property area. The only details found were found in summary

reports by Rodríguez S. (1995), Phelps (2002), Medrano (2000), and by oral

communication to the writers by George Phelps, P.Eng. and by Mr. Alberto Weber

Ramirez. No details about the Property have been published by the Consejo de

Recursos Minerales (1994,1994a). The writers did not check the file records of the

mining department in Hermosillo for past production records or other details.

The first reported mining in the Yécora area was at the San Francisco Mine, perhaps

as early as 1873, on the outcropping high-grade Colón gold-silver vein. Miners

excavated the open cut (Figure 3) and sunk a shaft, reportedly to a depth of 30

meters. Drifts and crosscuts were driven away from this shaft, and Pacific Rainier de

México, S.A. de C.V, intersected these workings in drillholes No. 95-1 and -6. Limited

mining was conducted, by an unknown operator, at the Lupe Alma Mine, located 1.4

kilometers SE of the San Francisco open cut. Exploration and limited mining also

was conducted on the California veins (Fig. 7), located 5.5 kilometers SE of the open

cut, where 2 silicified veins 1.5 and 2.5-3 meters thick were reported by Sr. Weber,

with the thicker vein having a zone 1.5 meters wide carrying gold grades of to at least

22.4 grams per tonne (“g/t”) gold. In 1990, Alberto Weber’s family mined and shipped

100 tons of ore, said to grade 17 g/t gold and 1 kg/t silver, from a trench located just

north of the San Francisco open cut. Many prospect pits are located in the Property

area, as at Maguarichi, La Cumbre, Puerto Los Huesos, and Cerro Colorado.

Previous operators constructed no milling or gold processing facilities on the

Property.

6.0 GEOLOGY6.1 REGIONAL GEOLOGY

The Property is situated in the Sierra Madre Occidental (“SMO”) physiographic

province (McDowell and Clabaugh, 1979; Clark, et. al., 1992), which is composed

principally of volcanic rocks divided into two groups, the andesitic Lower Volcanic

Series (“LVS”) and the felsic Upper Volcanic Series (“UVS”). The SMO is host to

many volcanic-related precious metal mines and deposits, such as La Cienega,

Tayoltita, Dolores, Mulatos, El Sauzal, Pinos Altos, and the nearby Ocampo and

Moris mines (Figure 2).

The oldest SMO lithologic units, exposed in the southeastern part of Chihuahua

and western part of Sonora, consist of clastic sedimentary rocks of Mesozoic age.

These rocks at the Moris Mine are a sequence of graywackes, quartzites, black

phyllites, basalt flows, “intrusives”, and occasional patches of silicified limestones,

were correlated by Valencia Gómez (1996) with the Triassic-Jurassic Barranca

Group strata. They may be further correlated with the black Las Trancas phyllites

of Triassic age which are host to the rich gold veins of the >9,000,000 ounce El

Oro gold deposit in Michoacán-México States. Granitic rocks may form the

basement in certain areas, as in Figure 5, which shows a comparison of certain

stratigraphic sequences in the Sierra Madre Occidental. The basement rocks in

the SMO locally are covered, as at the Moris Mine, by terrestrial polymictic

conglomerates.

A variably thick pile of andesitic volcanic strata of Upper Cretaceous to Middle

Tertiary ages overlies the conglomerates, corresponding to the LVS. It comprises

a variety of flows, flow breccias, and tuffites. A middle Tertiary dacitic sequence of

these rocks locally forms the uppermost part of the LVS sequence, and is often

present in areas which are host to gold mineralization, as at El Sauzal, Chihuahua

(Figures 2 and 5). This LVS composite sequence frequently was intruded,

especially in areas of gold mineralization, by late dikes and plugs of hypabyssal

10

andesite to rhyodacite, which post-date the initial cover flows of the overlying UVS

sequence strata. The most common UVS rock types found in exposures of the

SMO are rhyolitic ignimbrite sheets, flows, and dikes/plugs of Middle Tertiary

(Oligocene) age. These UVS sequences may be cut, locally, by andesitic, dacitic,

to rhyodacite-rhyolite dikes and domes. Granitic to dioritic plutonic to dike-form

rocks of variable age and composition intrude the LVS-UVS composite package.

Flows of basalt to basaltic andesite of Miocene age may lie atop UVS rock

sequences, and interformational sedimentary packages also are present locally.

Figure 6 shows the geology of this region, and Figure 7 the geology of the Property.

The mineralization in the gold-silver belt of the Sierra Madre Occidental is

principally of epithermal type, hosted in low-sulfidation silicification,

sulfidation/replacements, and quartz veins, although centers of vein-type to

disseminated high-sulfidation mineralization (Staude, 1995; Corbett and Leach,

1998) also are present. The andesites of the LVS are considered the most

favorable rock unit hosts for mineralization, although gold-silver prospects are

known in all the different rock types. The lithologic contact between the LVS and

UVS sequences is a particularly favorable horizon for gold mineralization in the

SMO, perhaps due to greater permeability than the adjacent rock units. The

basement phyllites below the contact with the LVS also are a preferred site for gold

deposition (e.g. El Oro). The conglomerates above this unconformity are an

untested target. Fault structures, of regional or local scale, play an important role

in the control of most precious metal mineralization in the SMO.

6.2 REGIONAL GEOPHYSICAL SURVEYS

The Consejo de Recursos Minerales has published aeromagnetic data (CRM, 2001)

which covers the Property area and the surrounding region. Figure 8 shows these

data, with reddish areas indicating magnetic highs and blue areas representing

magnetic lows. The most prominent feature shown is a narrow, linear, WNW-trending

11

aeromagnetic high, located just SW of the Moris-El Pilar gold-silver mining district.

The WNW-trending “Mojave – Sonora Megashear” (Anderson and Silver, 1979), a

major left-slip mid-Jurassic (?) shear zone, along which 700-800 km of displacement

is postulated (Sedlock et.al., 1993), occurs just north of the Mulatos mine. Structures

of this WNW to NW trend host major, low-sulfidation gold deposits at Ocampo and

Pinos Altos, and one of these structural systems on the San Francisco Property is

roughly parallel with a similar system at Ocampo (Figure 8). The WNW aeromag

high shown on Figure 8 may represent a similar, mega-scale structural feature. In

addition, numerous NNW- to NW-trending gold-silver vein zones are found at Moris,

Ocampo, La Republica, and at San Francisco, which may represent re-activated

ladder-vein, Riedel-type, “link-fault” shear structures connecting major WNW crustal

breaks originally formed during the “Megashear” episode.

6.3 PROPERTY GEOLOGY AND DEPOSIT TYPES

Figure 7 shows the geology of the Property, according to Espinoza (1999), as being a

broad sheet of UVS massive to spherulitic flows, crystalline to lithic tuffites and

volcanic breccias of rhyolitic to dacitic composition, covered by rhyolitic welded tuffs.

Within the UVS are local windows of basement LVS andesitic strata, comprising lithic

tuff and lesser flows and vesiculated amygdular basaltic andesite. A hornblende-

plagioclase monzodiorite porphyry plutonic intrusive stock and associated dikes are

present in the southern part of the Property area near the Nueva York and California

prospects, which locally have intruded the LVS andesites. A porphyritic, feldspathic

quartz monzonite hypabyssal porphyry body was mapped at El Trigo Colón, and a

dike of porphyritic dacite of unknown affinity is mapped as occurring at Maguarichi

(Espinoza, 1999). No basement rocks are exposed on the San Francisco property,

nor is depth to basement known.

Two main types of alteration are reported on the Property. The northern, La Estrella

concession area exhibits argillization and silicification of fractured, brecciated, and

mineralized host rocks. Local areas of quartz-iron oxide veinlets are present,

12

presumably after pyritic sulfides. The rocks in the southern part of the Property, on

the Chuchu concession, are affected by propylitization and possibly later-phase

argillization with quartz- iron oxide micro-veinlets. This area may represent a deeper

level of exposure below the UVS-LVS contact, in closer proximity to granitic plutons.

Structurally, from the California prospect (Figure 7) northward, the volcanic strata

strike dominantly NNW to NW, with moderate dips eastward, forming a large graben

structure. This direction of fracturing is associated with the Colón, Lupe Alma,

California, and Las Tapias gold-silver vein systems. In the southern, Chuchu part of

the Property, and earlier(?) WNW-trending set of faults and fractures are present, as

at Ocampo, which control the propylitic, more base metal-rich vein assemblages such

as are exposed in the Nueva York domain. This granitic core area exhibits a strong

circular fracture pattern on aerial photographs of the area.

Gold-silver mineralization is present within shear zones and associated fault gouge,

along with the alteration described above. The early phase (?) mineralization

associated with the WNW- to ENE-trending fault zones in the Chuchu concession

area are veins which are base-metal rich, containing sphalerite, galena, pyrite

chalcopyrite, bornite, and traces of molybdenite and silver sulfides. The samples

taken contain sub- 1 ppm gold values, along with high silver, copper, lead, and zinc,

and molybdenum values of 85-200 ppm Mo.

The main gold phase of mineralization, represented by the Maguarichi, San

Francisco, Lupe Alma, and California vein systems, is associated with NW- to NNW-

trending multi-phase brecciation, silicification and silica-(pyrite?) veining. Most of the

surface exposures are oxidized, but the rocks appear to grade into reduced rocks at

shallow depths. These systems locally carry moderate to high gold values (Figure 9),

with variable silver-to-gold ratios. The mineralization in UVS rhyolite at Maguarichi,

samples of which carried up to 13.08 g/t gold over a width of 2 meters, had low silver-

13

to-gold ratios. The Colón vein system at San Francisco carries moderate gold and

high silver values at higher elevations in the northern part of the system, whereas

below in the San Francisco open cut the vein system, 2 to 3 meters wide, carries

local very high gold values (to 34-102 g/t gold, with visible gold present), high silver,

lead, copper, and zinc values. The Lupe Alma vein system, present at the UVS-LVS

contact, carries low- to high-grade gold values in silicified high and low angle

(contact-?) breccia zones, with low silver and base metals. The California vein

system (Fig. 9), as described by Mr. Weber and assayed by Sanders (1993),

consisted of two quartz or silicified veins, 1.5 to 2.5 meters wide each, on which a

shaft was sunk. Values to 22.4 g/t gold were reported by Sanders, and spot samples

of 50-100 g/t Au were verbally reported by Weber. Neither the writers nor their

associates examined the latter site. The NW-trending system between the California

and Maguarichi systems is 10 kilometers long, though veins are not present

continuously along this entire length. Soil cover makes correlation and lateral tracing

of individual vein systems difficult, away from the prospect workings.

The vertical extent of mineralization on the San Francisco Property is not known, nor

is the depth to basement. Only 100 to 150 meters of vertical extent of the vein

systems is seen at the surface on the concessions.

7.0 PREVIOUS WORK BY OTHER COMPANIES

Various parties have conducted sampling programs on the Property, and several

companies have conducted substantive exploration work in the San Francisco

mine area (Fig. 3), as well as the adjacent Nueva York and Santo Niño properties

(Fig. 4). The early history of work on the Property has not been well defined, but

the first company to have been known to do substantive work on it was Minera Car,

S.A. in 1984. The writers have no written record of this work.

Pacific Rainier de México, S.A. de C.V. explored the property in 1995 (Maynard,

1995a, 1995b) and drilled 8 shallow holes in the San Francisco mine area (Fig.

10). They conducted surface rock and soil geochemical sampling, partly under the

supervision of Ing. Rodolfo Rodríguez and Greg Maynard, but only a summary

report of this work was available to the writers (Rodríguez S., 1995), that did not

include detailed sample locations or drillhole locations.

Phelps Dodge Exploration examined the Property (Espinoza, 1999), conducted

reconnaissance geologic mapping and rock geochem sampling, and discontinued

work on the Property after this effort. George Phelps, P.Eng. and Robert

MacKenzie examined and sampled the Property in 2000 (Phelps, 2000).

The writers examined the Property in 2000 for Barrick Gold Corporation, and

contracted Ing. Luis Medrano (Medrano, 2000) to sample selected parts of the

property. Barrick abandoned the Property without conducting further work.

No material exploration work has been done on the Property after Barrick in 2000,

and prior to its acquisition by Frontier Pacific Mining Corporation.

7.1 MAGUARICHI TARGET

The Maguarichi target (Figs. 7, 9) comprises zones of brecciation and multi-phase

silica- iron oxide veining in fractured, argillized rhyolitic or altered andesitic strata

near the UVS-LVS contact, breccias and dikes. The length of the mineral system is

not known, but system widths vary from 3 to at least 8 meters, where sampled.

The area is covered by substantial overburden, but moderate to high gold values

were found in sampling by Barrick, Mr. Weber, and by Dr. Fred Warnaars.

7.1.1 ROCK and SOIL GEOCHEM SAMPLING

The available outcrops were sampled by the junior author, Dr. Fred Warnaars, and Luis

Medrano, taking rock chip samples by hand. The samples were analyzed by fire assay and

Induction Coupled Plasma trace element geochem techniques by Chemex Laboratories in

Chihuahua City. A zone of moderate to high-grade gold-silver mineralization was found,

localized in the brecciated rhyolites, the bounds of which could not be determined, due to

colluvial overburden. The samples show low pathfinder trace element concentrations.

Significant results of the rock sampling included:

7.2 SAN FRANCISCO – LUPE ALMA TARGET

The San Francisco – Lupe Alma target (Figs. 7, 9) comprises zones of fault-

controlled brecciation and multi-phase silica-sulfide-oxide-iron oxide veining in

fractured, argillized LVS andesitic strata and fault breccias dikes, near the contact

with the UVS. A 10+ meter wide hanging wall zone of argillic alteration is present

in the San Francisco open cut. The veins have been termed the “Colón” vein

system at the San Francisco mine, and extends roughly from what is called the

“Silica Trench” at 3,137,980N for 1.5 kilometers southeast, to the south end of the

San Francisco open cut. The system, offset by faults, may extend southeastward

for an additional 1.5 kilometers to the Lupe Alma area. Widths vary from 2 to as

much as 10+ meters at the Silica Trench, where sampled. This area is covered by

substantial overburden, but is moderately well exposed in the San Francisco open

cut, where high gold-silver values were found in the rock chip sampling.

7.2.1 ROCK and SOIL GEOCHEM SAMPLING

Many of the available outcrops in the San Francisco – Lupe Alma target area were

sampled by Barrick, Dr. Fred Warnaars, Luis Medrano, and Espinoza (1999), taking rock

chip and channel samples by hand. The samples were analyzed by fire assay and

Induction Coupled Plasma trace element geochem techniques by Chemex Laboratories

in Chihuahua City.

Zones of moderate- to high-grade gold-silver mineralization were found, localized in the

andesitic fault breccias. The high-grade areas sampled show occasional visible gold,

local amethystine quartz, local galena and wulfenite-mimetite, local argentite, sphalerite,

azurite, chrysocolla, and a variety of weathering oxidation products from these minerals.

In contrast to mineralization in the UVS, higher base metal- and pathfinder trace element

concentrations are found in the Colón vein system.

7.2.2 Geophysical Surveys

The only geophysical survey over the Property that the writers are aware of was a

“Fraser Filter” VLF (very low frequency) survey by Maynard (1995), at the San

Francisco open cut. Maynard delineated two parallel “conductivity anomalies”, one

atop the main Colón vein and one 50-60 meters to the east.

7.2.3 DRILLING

Eight holes were drilled into the San Francisco open pit area, sited along a NNW-

SSE line just east of the outcropping Colón vein, by Pacific Rainier in 1995, as

listed in Table 4. The writers were able to locate only one of these drillsites with

certainty (712974E, 3136565N), from which DDH-1 and DDH-6 were drilled, due to

the lack of adequate maps and geographic coordinate data provided to the writers

18

by past lessees. Pacific Rainier drilled the holes using diamond core drilling, but

the methods of core handling, preparation, core splitting and sampling used are not

known. These core samples were assayed by Acme Analytical Laboratories, a

large, professionally accredited assay laboratory, which operates according to

industry standards. The junior writer did review copies of original assay

certificates, but did not have access to geologic logs of the drillholes or

documentation of sampling, bagging, security, and transportation practices used in

the drilling programs of Pacific Rainier. A summary of the significant results from

each of the known drillholes completed at the San Francisco prospect is given in

Table 4. No true thicknesses were given or calculated for the drill tube-length

intervals given below, which shows gold and silver values in grams per tonne.

Drillholes DDH-1 and DDH-6 were targeting the high-grade Colón vein in the San

Francisco open cut, just south of the location monument (Fig. 3). The drilling

intersected a vein in DDH-1, which carried 29.76 g/t gold and 142.8 g/t silver

between 49.4 to 50.15 meters in the hole, which is nearly a true thickness. Hole

DDH-6 was drilled vertically from the same spot as DDH-1, and was stopped in

19

mineralization at 62.2 meters, because of drilling problems. Jim Sanders (pers.

comm., June, 2002) stated that they may have intersected an old mine working,

and that they had to abandon the hole because they could not cement it.

Hole DP-1 likely was drilled in the open cut directly upon the Colón vein, because

the interval between 0 and 0.91 meters assayed 49.7 g/t gold and 283.6 oz./ton

silver. The collar location of this hole and the others for which the writers had

assay certificates was not exactly known.

7.3 CALIFORNIA - PUERTO LOS HUESOS TARGET

7.3.1 ROCK and SOIL GEOCHEM SAMPLING

The junior writer and Dr. Fred Warnaars collected surface rock chip samples from

the Puerto Los Huesos area, located in the northwestern part of the Chuchu

concession, and southeastward into the Martha 2 concession (Fig. 4). A large

portion of this area is heavily bleached and altered, comprising andesites and

argillized and sericitized intrusive felsic porphyries, perhaps similar to the one

mapped at the Maguarichi prospect by Espinoza (1999). These rocks are cut by

NNW-trending fault zones which contain gold mineralization, The California vein

system is located still further southeast, 200 meters north of the stream junction

with arroyo Nueva York (Fig. 9). Sanders (1993) and Weber described this locality,

which contains NW-trending and WNW-trending silica veins in andesite, carrying

high-grade gold values over 1 – 1.5 meter widths, being similar to the ones in the

Nueva York area further south. A shaft was sunk on one of the California veins

and a 25-meter adit was driven on this vein system, which were not examined by

the writers.

Significant results of the rock sampling included:

8.0 INTERPRETATION and CONCLUSIONS

The exploration targets on the San Francisco Property are NW- WNW- and possibly

certain NE-trending, moderately to steeply-dipping fault zones which are known to

host epithermal gold-silver mineralization. Breccia zones which cut UVS rhyolitic rock

sequences, such as occur in the Maguarichi area, also are potential hosts for gold-

silver mineralization. Work conducted on the Property by previous investigators has

formed a good geologic and geochemical database framework, from which Frontier

Pacific Mining Corporation may proceed with further exploration, to define possible

new ore zones on the Property.

Maguarichi Target: The Maguarichi target is a high-level, SMO low-sulfidation

epithermal gold-silver system, which appears to be hosted in breccias of

undetermined origin in felsic UVS strata, near the contact with the underlying LVS

andesitic rocks. Mineralization is associated with multi-phase silica veining, and with

fractures systems which have NW and NE trends. The presence of mineralized fault-

controlled vein systems in this area is established, but not whether viable breccia-

hosted systems of economic size and grade occur. The geologic mapping of the

Maguarichi area is insufficient to allow resolution of this problem. Sampling has

established that high-grade gold-silver mineralization does occur, partly in breccias, in

this target area.

San Francisco – Lupe Alma Target: The San Francisco – Lupe Alma targets are

SMO low-sulfidation epithermal fault-controlled vein systems, dominantly in LVS

andesitic rocks. The Lupe Alma system is at the contact with the UVS strata, and has

not been explored at depth by either mine workings or drilling. The Colón vein

system has a deeper, more base metal enriched mineralogy, but exhibits local +34 g/t

gold areas, and has an unusually attractive mineralogy, which potentially could be

exploited for collector’s mineral specimens, such as amethyst, wulfenite-mimetite,

and wire-leaf native gold. Drilling has established the presence of high-grade gold-

silver mineralization at shallow depths below the surface.

22

California – Puerto Los Huesos Target: These targets areas contain SMO

low-sulfidation epithermal fault-controlled vein systems, dominantly in LVS andesitic

host rocks. The Puerto Los Huesos system is insufficiently well mapped to determine

whether intrusive-hosted disseminated gold systems may be associated here with the

felsic porphyry intrusives. The widespread argillic and local sericitic alteration at

Puerto Los Huesos suggests the possibility of this occurrence. Fault systems which

carry elevated gold values also cut these rocks. The high tungsten value found in

one sample (0227) could be indicative of intrusive-hosted mineralization.

The California – San Jose vein systems have not been examined by the writers, nor

are sufficiently well described by others. They appear to be SMO fault-controlled low-

sulfidation epithermal veins in LVS andesites, near contacts with granitic intrusive

rocks which may be older and genetically unrelated to the epithermal quartz-gold

mineralization. The nearby Nueva York veins, which contain lower gold and higher

base metal values, may be an early phase of mineralization associated with the

Tertiary granitic rocks. The California – San Jose veins may be a separate, later-

phase, higher-gold system more similar to the Colón vein system.

The vertical extent of mineralization in the Yécora District has not been established,

as no deep drilling has yet been done. The SMO gold-silver vein mineralization in

the nearby Ocampo District, located 50 kilometers to the east-southeast, also is

associated with WNW to NW-trending regional fracture zones (Fig. 8), and has a

vertical extent of ore grade gold-silver veining of at least 700 meters. Only 100 to 150

meters of vertical exposure below the UVS has yet been tested in the San Francisco

Property area.

23

9.0 RECOMMENDATIONS

In the opinion of the writers, the character of the Property is of sufficient merit to

recommend that the following phased exploration program be conducted:

1) Geologically map and sample the Property at a scale of 1:10,000, using Brunton-

GPS control, and sample any altered and/or mineralized outcrops found during the

mapping effort. Prioritize the existing gold-silver target areas.

2) Trench and doze away overburden over selected target areas to expose bedrock.

Geologically map and sample the new exposures. Re-prioritize the targets areas.

3) Contingent upon favorable results, conduct a follow-up program of drilling two 60-

degree angled HQ wireline diamond core holes to test prioritized, mineralized

breccias, intrusive bodies, and/or structures at depth.
