Minto is a high-grade breccia pipe, drilled from surface to over 800 metres depth. The historical resource at Minto consists of a pod of carbonate sulphide breccias, with ~204,000 tonnes grading 0.2 oz/t (6.9 g/t) to a depth of 229 metres (750 ft). Refer to the note on historical resources on this page.
Notable Drill intersections at Minto include:
- 18.2 gpt Gold (7.9 gpt if cut to 31.1 gpt) over 65.7 metres and 4.61 gpt Gold (3.5 gpt if cut to 31.1 gpt) over 79.6 in drill hole MC-09-02
- 13.3 gpt Gold (11.0 gpt if cut to 31.1 gpt) over 82.5 metres in drill hole MC-09-01
- 1.15 gpt Gold over 280 metres, including 5.2 gpt Gold over 3.44 metres, 3.2 gpt Gold over 5.47 and 3.4 gpt Gold over 41 metres in drill hole MC-10-03b
- 1.01 gpt Gold over 192.0 metres, including 5.04 gpt Gold over 24.4 metres in drill hole MC-11-11
In spite of seeing very high grades, including abundant visible gold, Minto’s breccia requires additional work to increase tonnage and recoveries to boost its gold ounce per vertical metre. The proposed work program is aimed at confirming the width of the mineralized breccia at depth (below 229 metres), beneath the diabase dyke. The discovery of new breccia pipes could significantly improve the economics and increase the scale of Minto.
