T? INTRODET ION

This report contains the resu l t s and reconmendations from a geological

and geochemical exploration program conducted over the Kelsall Lake claim

group in noxthwestern Br i t i sh Columbia. The object of the program was t o

assess the significance of s i l t anomalies on the claim group. Kelsall

Lake is s i tua ted 2 miles ea s t of the Haines highway, some 10 miles South

of the Yukon - Bri t ish Columbia border (Figure I ) .

The wr i te r was assis ted i n the f i e l d by Mr. William Ostafichuk of Ottawa,

Mr. Dan Ph i l l i p s of Whitehorse and M r . John Tarde of Montreal. Helicopter

support was provided by Trans North Turbo A i r Limited of Whitehorse; and

expediting services by Terricon Enterprises Limited, a l so of Whitehorse.

The time and cos t s of undertaking t h i s program are recorded i n Appendix I.

GEOLOGY

The area was mapped on a scale of 1 inch - 3,000 f ee t . Local r e l i e f

is approximately 1200 feet and the area is open and t ree less . Outcrops

were only found on the northeast ridge and on a small ridge t o the

southwest (Figure 2). A large mass of d io r i t e or meta-andesite outcrops on

the northeast ridge and plateau. Andesite outcrops south of the d io r i t e ,

and intercalated bands of limestone, rhyol i te , and andesite outcrop t o t the southwest. Northeast and northwest trending f a u l t s cut the area.

GBOCHEM STRY

Soi l s i n the area are transported and immature, Samples were

collected by spade from ei ther the "B" or "C1' horizon and were analized

by Barringer Research Limited i n Whitehorse by acid digest ion and atomic

adsorption f o r Cu, Pb, and Zn.

Soi l samples were collected a t 100 foot in te rva ls along l ines 300

f e e t apar t (Figures 3 - 6 1. No s ign i f ican t Pb anomalies ex i s t ,

Several s ign i f ican t Zn anomalies occur between l ines 12 + OOS and 45 + OOS

and the base l i ne t o 18 + OOB. The pronounced Zn anomaly west of the base

l i ne between 33 + OOS and 39 + OOS is probably associated with stream

dispersion. Copper anomalies are more widespread than zinc. The most

s ign i f i can t l i e between l ines 12 +OOS and 42 + OOS and generally coincide

w i t h the Zn anomalies i n t h i s area. The d i f fuse Cu anomalies on the

east s ide of the grid may be due t o a higher background associated with

the d i o r i t e . The anomalies are somewhat discontinuous, but t h i s could be

expected on s teep slopes w i t h transported s o i l s .

CONCLUSIONS AND RECOMMENDATIONS

Several s ignif icant Cu and Zn anomalies occur on the grid, but no

fur ther geochemical work is warrented.

It is recommended that a reconnaissance type B-M geophysical survey

be run over that pa r t of the grid containing the geochemical anomalies. It

should cover the area from 6 + OOS t o 45 + OOS and from the base l i ne t o

18 + OOB. Pickets w i l l have to be placed on the grid before the

geophysical survey can be undertaken, This spec i f ic area should a l s o

be mapped on a scale of i inch t o 300 f ee t .
