Hardworking goldie Mt Malcolm Mines has completed its intensive RC drilling program out at Dumbarton in Victoria, making a total advance of 1,612m, from a 14-hole program which kicked off  back in October.

The Aussie-listed digger reports significant peak intersections which include:

  • 22DBRC0008 4m @ 2.52g/t Au (25-29m) including
    • 1m @ 9.11g/t Au (26-27m)
  • 22DBRC0010 5m @ 1.18g/t Au (0-5m) including
    • 1m @ 2.39g/t Au (3-4m)
  • 22DBRC0011 6m @ 0.62g/t Au (34-40m) including
    • 1m @ 1.59g/t Au (37-38m)
    • 2m @ 0.48g/t Au (44-46m)
    • 1m @ 0.22g/t Au (57-58m)
  • 22DBRC0013 2m @ 1.08g/t Au (47-49m)
  • 22DBRC0016 6m @ 0.75g/t Au (28-34m) including
    • 1m @ 1.63g/t Au (28-29m)
    • 4m @ 0.74g/t Au (38-42m) including
      • 1m @ 1.74g/t Au (41-42m)

Yowzers!

No, that’s not all

M2M’s latest program drilled from mid to late last month was designed to test and confirm the strike extensions of the old workings and to determine the architecture and characteristics of the lode system, as well as following up significant intersections returned in 22DBRC0004 and 22DBRC0005 from as far back as May.

At Dumbarton, Mt Malcolm (ASX:M2M) has identified significant gold mineralisation at depth (77-97m) as evident in 22DBRC0005. The Dumbarton opportunity is made up of two historic workings approximately 320m apart.

Peak intercept

The RC drilling program intersected several shallow shear zones and related mineralised quartz veining systems in carbonated basaltic host rock with hole 22DBRC0019 owning the peak intercept of 8m @ 2.21g/t Au (28-36m)  which included 1m @ 10.60g/t Au (31-32m).

M2M says the Dumbarton “line of lode zone” system remains open at depth having returned numerous anomalous historical and recent drill intercepts including a peak result from the inaugural M2M drill campaign of 20m @ 1.34g/t Au (77-97m) including 7m @ 2.22g/t Au (77-84m) with 1m @ 3.58g/t Au (78-79m) in 22DBRC0005.

This mineralisation is associated with quartz veining and carbonate alteration in sheared and foliated basalt, minor sulphides on or near intrusive dolerite contacts.

Historic standards

Production records from the gold boom of the last century returned 210.58 oz from 388t (16.88g/t Au).

Along the Dumbarton lode M2M can trace up to three parallel zones of shearing and quartz veining hosted by basalts returned numerous intersections in drilling campaigns conducted by Torian Resources RC drilling (2017).

The exploration target model and the Dumbarton lode target area are comparable with the geology, structural orientation and mineralisation styles observed in old mines to the north at the nearby but excised Richmond Gem and North Star workings, 1-2km away.

The underground mines were two of the districts richest and best high-grade gold producers (1897-1933) yielding a total gold production of 39,611 ounces, the vast majority of which was processed prior to 1915 (Kelly 1954).

The mineralised Dumbarton vein hosted lode system has not been systematically drill tested over its known strike length nor at depth.

Potential Dumbarton lode extensions

The company says that beyond the identified 400m long mineralised halo remains a semi-tested target zone.

Due to the historical and recent positive gold results it’s the companies intent to confirm and extend known gold intersections with RC drilling.
