Legend Mining Limited’s (ASX:LEG) assay results from diamond drill hole RKDD034 confirm that it is the best hole to date at Mawson prospect within the Rockford project on Western Australia's Fraser Range.
Assay results from the massive sulphide intersected in RKDD034 have resulted in the thickest and highest-grade massive nickel-copper sulphide intercept at Mawson to date.
The hole assayed 31.1 metres at 2.80% nickel, 2.04% copper and 0.15% cobalt from 200.7 metres with nickel values up to 3.26%, copper values up to 3.84% and cobalt values up to 0.17%.
This speaks to the potential for more mineralisation to be discovered at Mawson as the drilling footprint expands with phase 1 metallurgical test-work on the massive sulphide domain underway.
Mineralised system of substance
Legend managing director Mark Wilson said: “These assay results are further confirmation of our earlier assessment that hole 34 is the best hole drilled at Mawson to date.
The combination of the widths and grades of the massive sulphides in this hole support our conviction that we are dealing with a mineralised system of substance at Mawson.
“The purpose of the hole was to conduct phase 1 metallurgical tests and the results of this test-work will be reported once received.
2021 field season
“Meanwhile further assay results from 2020 drilling programs are rolling in for compilation and assessment.
Once integrated with existing data, they will assist in future drill planning for the 2021 field season.”
Assay results
The diamond drill hole RKDD034 was designed as a twin of RKDD008 for phase 1 metallurgical test-work on a representative massive nickel-copper sulphide domain of the mineralisation identified at Mawson.
A total of 43.1 metres of massive nickel-copper was intersected downhole.
Future programs
Mawson’s future programs include:
➢ Phase 1 sighter metallurgical test-work on massive sulphide from RKDD034 underway;
➢ Integration of diamond drilling, reverse circulation, aircore geochemical and geophysical datasets to evolve 3D emplacement model of Mawson, with new constrained gravity and magnetic inversions underway; and
➢ Diamond and RC drill hole planning/design for 2021 field season at Mawson underway.
