Mt Malcolm Mines will restart drilling on one of the most prospective historic gold zones across its Leonora gold tenements, with a 15 hole RC program to test the Dumbarton gold prospect.

Dumbarton sits beneath historic workings which delivered shallow, high grade gold in the late 19th and early 20th centuries.

The 1500m program aims to test and confirm strike extensions of the main shaft workings at Dumbarton, a second old working to the southern end of the lode system 320m away and follow up significant intersections returned from holes 22DBRC0004 and 22DBRC0005.

Numerous anomalous results have been returned from along the Dumbarton line of lode, which remains open in all directions.

The most recent successful hits from Mt Malcolm (ASX:M2M) include:

  • 22DBRC004: 6m at 2.86 g/t Au (36-42m), including 2m at 6.50 g/t Au (36-38m); and,
  • 22DBRC005: 20m at 1.34 g/t Au (77-97m) Including 7m at 2.22 g/t Au (77-84m) with 1m at 3.58 g/t Au from 78-79m.

Gold anomalism was identified in all five holes drilled in a shortened program which commenced in April this year, though the peak result in 22DBRC005 is at a different structural orientation and mineralisation style to the historical 70 degrees trending Dumbarton quartz vein basalt hosted lode system.

The RC intersection was struck around 150m south-east of the northern projected Dumbarton line of lode.

Three zones

The new Dumbarton drill program is the latest exploration initiative undertaken by M2M, which boasts a 274sqkm package surrounding the historic Malcolm Mining Centre 10-25km east of the historic gold town of Leonora.

It follows hot on the heels of a data review of the Emu Egg Prospect Area at the northern end of M2M’s extensive Eastern Goldfields tenement holding.

Completed to a depth of around 100m, the Dumbarton program is multi-faceted, targeting three major areas.

These include a pattern spaced on 40m centres following the line of lode around the main Dumbarton Shaft, which produced 210.58oz from 388t (16.88g/t) from 1899-1903, the area around the high tenor hit in 22DBRC005 and on a 50m by 50m grid at the southern zone.

This will evaluate the southern extension beyond the shallow historical RC drilling by Nova-Polaris Pacific in 1988 who intersected near surface gold mineralisation including:

  • DRC14: 4m at 4.74 g/t Au (5-9m), including 2m at 8.67 g/t Au (5-7m) & 1m at 1.1 g/t Au (13-14m); and,
  • DRC015: 1m at 1.61 g/t Au (17-18m) & 2m at 0.53 g/t Au (25-27m).
