Chase Mining Corporation Ltd (ASX:CML) recently completed a 6-hole deep diamond drilling program for 2,928 metres targeting the high-grade gold (plus copper and silver) at the Lorraine Nickel Mine in Quebec, Canada.
The recognition of visible gold during logging in holes CM-20-01 and 02 and the unexpected widespread silica-carbonate alteration and different ages of structurally related veining and minor sulphides necessitated the re-logging and sampling of holes already logged and sampled.
This process has caused delays in the dispatch of samples for assay.
Fine-grained visible gold at 484.5 metres downhole in CM-20-01
Hole CM-20-06 was the first hole to be fully logged, photographed, cut and sampled and the core was delivered to the laboratory in Sudbury on August 12.
A total of 388 mostly 1-metre long samples covering 376 metres of the 456 metres total hole depth were selected for assay which equates to about 83% of the core sent for assay.
Samples from the other 5-holes plus 77 samples from hole CM-19-07 drilled in 2019 but not sampled, were delivered in late August.
Fine-grained visible gold at 508.7 metres downhole in CM-20-02
The total number of samples submitted for assay are 1,877.
Progress at the lab has been affected by COVID-19 restrictions, but hole CM-20-06’s batch of 428 samples (including duplicates, standards and blanks) has been fully processed waiting for analysis.
Processing of the other hole sample batches and assays will follow as per delivery dates.
