TIGER CLAIM

AINSWORTH, SLOCAN MINING DIVISION, B. C.

SUMMARY

A programme of soil geochemistry on the Tiger claim did not

locate new targets f o r exploration. Assays of mineralization in

picked samples from dumps are encouraging.

Underground mapping and sampling is recommended t o investigate

the possibility that the deposit is bedded rather than vein-type.

Cost of the programme is estimated to be $4400.00.
