which is co-incident in silver and zinc ( L 7+20 N, 1+80W). H strong

lead anomaly occurs 300 metres west at 4+80W. This lead anomaly

occurs near the contact between the limestone lens and the

greenschist to the southwest. 4 second strong zinc anomaly occurs

at 2+40E on L7+20N. There are five scattered copper anomalies, but

they are considered of low priority.

The recent discovery af auriferous massive sulphide

mineralization by Rea Gold Corporation in the same geological

formation approximately 24 kiiometres west of the property indicates

that even low threshold anomalies cannot be totally disregarded.

A1 though the geochemical anomalies are not extensive, three

areas do indicate highly anomalous values in lead, zinc, and silver

and these areas warrant further testing by EM Sctrveys and bulldozer

trenching to expose bedrock. The cost of this program is estimated

to be $40,00(:). If f avourable results are encountered, a preliminary

stage of diamond drilling would be warranted. A program of

approximately 1000 metres of diamond drilling costing about $150,0(:)C)

GOLD GEOCHEMICAL ANALYSIS BY MIN-EN LABORATORIES LTD.

Geochemical samples for Gold processed by Min-En Laboratories Ltd., at 705 W. 15th St., North Vancouver Laboratory employing the following procedures.

After drying the samples at 9 5 O ~ soil and stream sediment samples are screened by 80 mesh sieve to obtain the minus 80 mesh fraction for analysis. The rock samples are crushed and pulverized by ceramic plated pulverizer.

A suitable sample weight 5.0 or 10.0 grams are pretreated with HN03 and Hc104 mixture.

After pretreatments the samples are digested with Etraa Reqia solution, and after digestion the samples are taken up with 25% HCl to suitable volume.

Further oxidation and treatment of at least 75% of the original sample solutions are made suitable for extraction of gold with Methyl Iso-Butyl Ketone.

With a set of suitable standard soaution gold is analysed by Atomic Absorption instruments. The obtained detection limit is 0.005 ppm (5ppb) .
