Chase Mining Corporation Limited (ASX: CML) has announced a positive update on its Alotta project in Canada.
The company said that diamond drilling had commenced at the high-grade Ni-Cu Alotta Prospect over the weekend.
The company reported that hole ZA-19-03 was completed at 102m with 41m of visually logged massive and net textured sulphide mineralisation intersected in a mostly mineralised zone from 32m to 73m downhole.
It may be noted that the 41m mineralised intercept is the biggest downhole mineralised intercept to date at Alotta.
The company said that a second zone of massive sulphides of 1.2m was intersected from 86.60m to 87.80m.
Chase mining reported that the drill core has yet to be routinely photographed, detail geologically logged, cut and sampled. The information released is from the ‘quick log’ (rock type and mineralisation).
The company said that the rig has been relocated to Hole ZA-19-04.
The Alotta-Delphi-Zullo project is located at the Belleterre-Angliers Greenstone Belt (BAGB) in the Pontiac Subprovince south of the Abitibi Greenstone Subprovince within the Superior Province of the Canadian Archean Shield and north of the Proterozoic Grenville Front.
One of the significant prospects of the project is the Alotta prospect.
Drilling at Alotta prospect
The company reported that a diamond drill programme of 600 to 700m commenced on the weekend at the Alotta Prospect. The October 2019 diamond drilling programme currently comprises six angle holes varying in depth from 102m to 120m.
The company said that the 5 or 6 holes will target extensions to known mineralisation within the Ni-Cu wireframe; as well as test the interpreted Alotta Deeps position, a shallow downhole electromagnetic (DHEM) plate, and the potential WNW extension of the main mineralised zone.
The current drill programme is a follow-up to an October 2018 programme.
The company has now reported two holes, ZA-19-03 and ZA-19-04 from the current October 2019 diamond drilling programme.
Chase Mining reported that hole ZA-19-03 was drilled within the Ni-Cu wireframe, but obliquely to the previous holes to better understand the internal geology and structure of the deposit.
The hole also targeted the extension to depth of the mineralisation and the footwall Quartz-Feldspar-Porphyry contact zone.
The company said that the core has yet to be routinely photographed, geologically logged, cut and sampled.
CML said that from the ‘quick log’ (rock type and mineralisation), the hole ZA-19-03 intersected 41m of massive sulphides and net-textured sulphides from 32m to 73m downhole.
The company reported that the 41m mineralised intercept is the biggest downhole mineralised intercept to date at Alotta.
Chase Mining said that from 73 to 86.6m downhole feldspar porphyry with trace pyrite was intersected, then 1.20m of massive sulphide to 87.80m.
Hole ZA-19-03 was completed at 102m.
CML noted that the uncut core and widths of mineralisation show similar visual characteristics and tenor as previously reported for the Alotta high-grade mineralisation (Ni-Cu-PGE-Co).
CML reported that hole ZA-19-04 that is currently underway is an uplift on hole ZA-18-05 which had previously returned 11.28m at 2.17% Ni, 2.15% Cu, 2.94g/t PGE and 0.11% Co from 61.15m.
The company said that the aim is to expand this zone upwards and the hole ZA-19-04 will continue into the footwall to test the extent of the net-textured sulphide mineralisation associated with the gabbro body along the northern margin of the wireframe model.
Updates and next steps
The company said that no assay results are being reported and no core has been cut or submitted for assay. CML reported that the drilling is ongoing and the rig has been relocated to Hole ZA-19-04.
