About Great Northern
Leases Type: Mining
Primary Commodity: Gold (Au)
Located in the Central Goldfields of Western Australia, 15 kilometres east of Leonora is the Infinity Mining Great Northern tenement. The Great Northern tenement is a mining lease with its prospective commodity identified as gold.
The Great Northern Workings are on a strike approximately 80 metres long and dip steeply to the north-east. These historic workings include exposed stopes with an offset shaft on the north-east side. Historical production is recorded as 460 tonnes, with an average grade of 21.9 grams per tonne of gold. Whilst past drilling was not carried out on a recognizable grid, a cross sectional inferred resource was calculated.
In January 2022 Infinity Mining undertook a 724 meter drill program with samples submitted for assay. This drill program was designed to mirror a previous drill program completed in 1987 and 1988. In March of 2022, Infinity Mining announced the results of this campaign showing significant gold intercepts that including the following;
- 5m @ 2.48g/t from 37m depth in hole GN22RC101
- 4m @ 3.68g/t from 30m depth in hole GN22RC111
- Including 1m @ 10.95g/t from 32m depth in hole GN22RC111
Detailed 3D modelling can now incorporate the most recent drilling for a potential updated JORC resource report. Great Northern is just part of Infinity Mining’s 13.8 square kilometre Central Goldfields portfolio.
Historic Gold Production 20 Times Greater than Kalgoorlie Pit
- The workings are on a strike of approximately 80 metres long and steeply dip to the north-east. There are exposed stopes on the strike with an offset shaft on the north-east side.
- Recorded production from this area spans three separate phases totalling 460 tonnes for ~356 oz @21.9g/t.
- In 1987/88 Melita Mining drilled a series of RC holes. Results are contained in report A25349
- Several holes intercepted gold grades up to 26.4g/t but none of these holes had collar coordinates.
