PURPOSE OF THE WORK

During the 1979 field season sediments were collected from the

Hogem Batholith. One anomalous molybdenum value prompted the staking

o f the Osilinka claims in September. The staking of these claims was

immediately followed by an additional sediment sampling programe.

In the summer o f 1980 more work was carried out in and around

the claims.

molybdenum value in sediment #266.

WORK DONE

A high molybdenum value i n a sediment (#266) taken i n the Hogem

Batholith during a grassroots exploration program i n 1979 generated an

extension of the f ie ld season i n t h i s area. During this extended period

the Osilinka claims were staked and subsequently sampled i n order t o

confirm the h i g h value. Much s i l t sampling was done outside the boundaries

o f the claims due t o the rugged nature of the topography w i t h i n the claims.

Another reason for sampling outside the claim boundaries is the deter-

mination of background and threshold values.

In 1980 the work on and near the property was continued. This

work consisted of sediment and soi l sampling, geological surveying and

prospecting . The thresholds (mean value + two s t anda rd deviations) used for the

Osilinka claim are give below. These thresholds are a combination of

d a t a obtained from the regional exploration program and the property work.

The same values are used for b o t h so i l s and sediments.

A total of 14 days i . e . 70 mandays were spent on the Osilinka claims.

These include t rave l , set-up camp, work performed as well as bad weather days.

CONCLUSIONS

In sumary, the Osilinka claims have a complex history o f intrusions

and metamorphism compounded by at least three phases of dykes cutting

through the intrusive rocks followed by faulting. Some Mo mineralization

has been recognized either in veins, in moraine rubble o r boulders. More

detailed geology and prospecting is recommended.
