Chase Mining Corporation Ltd (ASX:CML) has established valid exploration drill targets for the first half of 2020 at its Alotta nickel-copper-PGE and Lorraine precious and base metals projects in Quebec, Canada.
Following highly encouraging results from both projects, including bonanza-grade copper and palladium from Alotta and gold at Lorraine, the company is formulating further drilling and exploration plans.
At Alotta, the company’s consultant Orix Geoscience has compiled geological cross-sections and a long-section for the recently completed diamond drill program.
Hole ZA-19-05 returned a bonanza-grade intersection of chalcopyrite-pyrrhotite massive sulphide assaying 22% copper + 34g/t palladium + 3.5g/t platinum and 0.78% nickel, 1.4% zinc and 65g/t silver.
The 0.5-metre intercept from 55.3 metres was part of a wider 4.1-metre zone of mineralisation assaying 5.3% copper, 4.9 g/t palladium, 0.9 g/t platinum, 0.26% nickel and 12 g/t silver.

New mineralisation style
This is a new style of mineralisation and mineral assemblage previously unknown at Alotta within a feldspar porphyry intrusive.
It is quite different from the usual nickel-copper-PGE-silver association of the nickel-copper massive sulphides and its recognition may indicate the discovery of additional high-grade potential at Alotta.
This bonanza zone of porphyry mineralisation is open at depth and along strike to the ESE of the drill section and may well persist outside the wireframe outline to the ESE.
There is only wide-spaced historic drilling to the ESE which will assist in the targeting of the planned follow-up 2020 drill program.
The recent seven-hole drill program for 705 metres mainly targeted extensions to known mineralisation within the nickel-copper wireframe and a shallow downhole electromagnetic anomaly.
One hole was continued to the footwall contact of the wireframe model.

Overall the drilling confirmed the continuity of the wide zones of mineralisation intersected by the maiden 2018 drill program and intersected a number of additional high-grade nickel-copper-PGE massive sulphide zones.
One hole, ZA-19-03, indicated continuity of mineralisation within the wireframe model with a +40-metre intercept.
The company is now assessing these results and the importance of the bonanza-grade intersection in hole ZA-19-05 to formulate a further drill program.
The planned Alotta drilling alongside the gold drilling program at the Lorraine Nickel Mine site provides the company with very valid exploration drill targets for the first half of 2020.
