Nice score vermkart,
This explains the delay very well.
Only two days till they exit quarantine to.

On looking over sherritt mining records, 100 anomalies exist, 10 were drilled for the existing deposits, 90 were never drilled.

The nickel and copper are primary metals and cobalt, gold, platinum and zinc are tertiary metals in the ore.

Sherritt was not able to recover the zinc, platinum and gold in the nickel process.

So there is proof gold exists there by the old tackers and sherritt records.

Its in trace amounts, its existence is interesting.
