SUBJECT: Examination of K & D Lode, Sunset Cove, Juneau ~ r e c i n c t . $ ~ "

On 25' June 1951, Leo He Saarela and James k . Williams examined and mapped t h e K & D Lode. Samples were not taken,

The property i s a gold and antimony lode owned by Herman Kloss and Jack Davis, The loca t ion i s a t Sunset Cove wllicg iq,.,' south of Win$ham,,Bay on the mainland a t coordinates of 1-33 32"u long. and 57 3 0 t % Lat, The workings a r e 2$ miles from the beach a t an e levat ion of 360 feet . The trail passes over a "hump1' 500 f e e t high enroute, but the lode i s ac tua l ly on the same creek t h a t enpties i n t o bunset Cove where t h e t r a i l leaves the beach.

The underground workings consis t of an a d i t and a winze, o r incl ined shaft , which were mapped by L. H. Saarela, The map w i l l be included with t h i s report . hand h o i s t and hand pump are i n the shaft . The surface equipment includes a s m a l l mi l l ing setup with a very small b a l l mi l l . Two good cabins a r e maintained, one a t t he workings and one a t t h e beach. The t r a i l is very well maintained,

The mineralization i s i n the f o m of a large quartz vein system with off shoots carrying nat ive antimony, s t i bn i t e , galena, sphaler i te , arsenopyrite, jamesonite, gold, and others. The main vein i s up t o 25 f e e t thick, s t r i k ing ~ 6 0 % and dipping 45' t o 50' Kd. The quartz i s very f ractured and occurs i n parallel l ayers (nribbony") from one t o six inches th ick through t he f u l l width of the vein.

The vein l i e s conformably with t h e bedding of a graphi t ic t o a curly gray sch i s t . The i n i t i a l fractures were undoubtedly f i l l e d with solut ions and continuing s t r e s se s with many stages of mineralized so lu t ion f i l l i n g resu l ted i n t h e ore deposit. Un- doubtedly those areas of maximum shearing w i l l be found t o contain the be s t ore when t he deposit i s sanpled a s shearing allowed f r e e

c i r cu l a t i on of solutions.

Much l a t e r on the plane of vein movement was noted i n the workings (see map) which indicates continuing movement a f t e r deposition,

From a mineralagical standpoint, the most in te res t ing fea ture of the deposi t is the antimony, which is i n a native s t a t e occupying the l a t e f rac tures and shears. Native antimony is a r a r e occurrence. k l a rge specimen of t h i s mineral was given t o the Department, courtesy of Herman Xloss.

A Victoreen Model 26% Geiger Counter was used i n a thor- ough check of the underground workings and surface exposures i n an e f f o r t t o de tec t t he presence of radioactive minerals, The r e s u l t s were negative.

A check w a s a l so made f o r f luorescent minerals underground with an u l t ra -v io le t lamp. Considerable fluorescence was found, but it was spotty. It was t he orange fluorescence of hyd.rozincite, an a l t e r a t i o n p r o d ~ ~ c t of sphaler i te .

The a d i t was d r i f t ed along the vein, a s shown on the map, and the inclined s h a f t was sunk on the dip of the vein, cross ing the a d i t on the way down. The s h a f t was f u l l of water t o the l e v e l of the f l o o r of the d r i f t . Kloss reports t h a t a shor t d r i f t was driven a.t the bottom of the shaf t . There are a number of open pits exposing the vein upstream where t h e mineralization is a l s o good. The creek follows the strike of t he vein and exposes it well i n a number of places c lose tca the workings. d loss claims t h a t these exposures can be seen fo r a dis tance of nearly 2000 f e e t up the creek, and t ha t the vein is pe r s i s t en t a l l t he ray.

s ince t he vein is so well exposed along t he s t r i ke , it is suggested t h a t f u tu r e development work be directed downward from the bottom of the ex i s t ing s h a f t i n order t o be t t e r determine the s i z e and mineralization of the vein i n depth. T h i s would a l so block out a comparatively l a rge ton.nage.

I n regards t o sanpling the deposit, dianond d r i l l i n g appears t o be r a the r impractical f o r the reason t h a t a very l a rge number of holes would have t o be slmk t o prove the vein. Also, considering the "ribbonyir character of the vein and many s tages of mineral deposition, if one were t o properly channel sample the deposit, each separate band should be channelled individually t o f i nd exactly where the values l i e .

There i s not s u f f i c i e n t antimony i n t he ve in as exposed thus f a r t o make the deposit valuable f o r antimony alone. The large variety of minerals associated here w i l l make a very complex

mil l ing problem, If a simple,cheap method of separation can be arranged, it is possible t h a t the property could be made t o pay on gold and antimony values .together. A good plan would be t o make experimental m i l l runs with the mineralized material from fu tu re development work, ca re fu l ly checking r e s u l t s and noting recovery eff ic iency from each run.

Conside~ing t he problem of t r a n s p o r k t i o n t o t h e beach, pack animals over the t r a i l would be the only p r a c t i c a l so lu t ion u n t i l such time as the property would g e t i n t o large production. If a tramway were t o be constructed, probably t he bes t YOU-te would be t o follow the creek, but the cos t of tramway construction i s prohibi t ive f o r small operations at the present time.

Respectfully submitted,
