The Millie Mack property is located near the top of Blue Grouse Mountain, approximately 12 kilometres east-northeast of Burton, BC. The property is accessible via a 24- kilometre gravel road along the north side of Caribou Creek.

Regionally, the area is underlain by limestone, slate, siltstone and argillite of the Triassic Slocan Group and basaltic volcanic rocks of the Lower Jurassic Elise Formation (Rossland Group). These have been intruded by granitic rocks of an un-named Middle Jurassic intrusion to the north and granodioritic rocks of the Cretaceous Whatshan Batholith to the south.

Locally, four zones (Millie Mack, Black Bear, Billie P and Great Western) within an area measuring approximately 750 by 1200 metres comprise the Millie Mack property. The occurrences are exposed in trenches and underground workings. The Millie Mack occurrence is located on a south- facing slope at 1820 metres elevation, whereas the Black Bear occurrence is located approximately 800 metres to the north west, on a west- facing slope, at an elevation of 1930 metres. The Great Western and Billie P occurrences are located approximately 800 and 1200 metres to the south west of the Millie Mack occurrence at elevations of 1750 and 1680 metres, respectively.

The main occurrence, the Millie Mack, is described as a 6 to 30- metre thick shear zone, dipping 12 degrees south east, containing deformed and boudinaged quartz veins hosted in graphitic schist and argillite of the Triassic Slocan Group. The Billie P quartz veins are reportedly deformed in a similar manner (Paper 1986-1, page 351), whereas the quartz veins in the Black Bear open pit follow the bedding planes and are not strongly deformed. Bedding attitudes are shallowly dipping and undulating.

The Millie Mack veins are located at the base of a section of Slocan Group clastic sedimentary rocks that overlie mafic volcanic rocks. There are two interpretations regarding the structural relationships: Geological Survey of Canada Bulletin 161 shows the contact as a low angle thrust, and describes the Slocan Group strata as a klippe thrust over younger volcanic rocks of the Jurassic Rossland Group (Elise Formation). The second interpretation would have the Slocan sedimentary strata in normal (unfaulted) contact with older volcanic rock (Geological Survey of Canada Open File 432). Slocan Group strata include sandstone, siltstone, argillite, tuff, andesite and volcanic breccia. They are locally calcareous and contain local pods of limestone. Rossland Group volcanics include volcanic breccia, feldspar porphyry and basalt.

Basal Slocan Group strata are highly sheared graphitic argillite, which contains blocks or boudins of vein quartz mineralized with pyrrhotite, pyrite, galena, sphalerite, chalcopyrite, arsenopyrite, tetrahedrite, argentite, native silver and cosaltite. The graphitic schist host rocks range from 3 to 10 metres in thickness and the tectono-clasts of vein quartz are erratically distributed within the unit.

In 1981, samples from a 2.83-tonne shipment of mill concentrate from the Millie Mack assayed 12.8 grams per tonne gold, 768 grams per tonne silver, 0.16 per cent copper, 2.5 per cent lead, 3.0 per cent zinc and 3.9 per cent arsenic (Assessment Report 9965, Paper 1986-1).

In 1982, a bulk sample of 13.6 tonnes is reported to have averaged 0.68 grams per tonne gold, 113 grams per tonne silver, 0.03 per cent copper, 0.60 per cent lead and 0.40 per cent zinc (Property File - J.L. DeLeen [1982-12-09]: Report - Section V - Millie Mack Property).

In 1989, the results from seven percussion drill holes were reported in the George Cross News Letter (number 178, 1989), with the highest assay being 3.5 grams per tonne gold and 419 grams per tonne silver across 3.05 metres in drill hole 89-15.

Also in 1989, a 41.7 tonne bulk sample from the ‘5800 Layer’ zone averaged 5.7 grams per tonne gold and 206 grams per tonne silver (Property File - The Northern Miner [1989-07-03]: News Clipping - Drilling to resume at Millie Mack). Smaller bulk samples, of 0.9 to 1.8 tonnes, from the other zones yielded: 0.44 gram per tonne gold from the Billie P pit, 0.68 gram per tonne gold from the Great Western pit and 1.03 grams per tonne gold from the Northwest adit, with 0.96 and 5.68 grams per tonne gold from the Millie Mack and lower Millie Mack zones, respectively (Property File - E.A. Schiller [1989-04-10]: Re: Dragon Resources and Greenstone Resources property review).

In 1989, a potential reserve of 1,542,070 tonnes grading 4.79 grams per tonne gold and 222.82 grams per tonne silver, within a larger area of 18,144,000 tonnes grading 2.7 grams per tonne gold and 154 grams per tonne silver (Property File - Dragoon Resources [1989-08-14]: No. 155 (1989) - Mille Mack Field Program For 1989 Well Advanced).
