The CMM property is located on Rudolph Ridge, immediately south of Deadman Pass on the Alberta, British Columbia border.

Locally, the Mississippian Carnarvon, Opal and Loomis members of the Mount Head Formation and the Upper Massive Member of the Livingstone Formation host potentially large tonnages of high-quality limestone. Rock types include lime grainstone, packstone, wackestone, and mudstone, some of which is dolomitic or chert-bearing or both.

In 2008, 131 rock samples were collected from the Mount Head Formation (Loomis, Opal, Carnarvon members) to assess the limestone quality. Complete descriptions of each member of the Mount Head Formation can be found in Assessment Report 30711.

The Loomis Member is comprised of a ooid-rich limestone sequence. Fifty samples were collected in locations representing approximately 175 metres of stratigraphy. A section atop the eastern crest of Rudolf Ridge averaged 87.71per cent CaCO3, 6.96 per cent MgCO3, and 4.10 per cent SiO2. Within a bowl-shaped valley on the northern side of Rudolf Ridge, samples averaged 93.37 per cent CaCO3, 4.88 per cent MgCO3, and 0.91 per cent SiO2 (Assessment Report 30711).

The Opal Member is generally comprised of thick massive grainstone with packstone to grainstone and mudstone in upper sections. The lower portion is a resistant, thick, generally high-quality limestone unit of massive, homogeneous, medium- to dark- greyish- brown, fossiliferous packstone to grainstone. A total of 37 samples were collected in two locations from the lower section of the Opal Member representing approximately 22.5 metres of stratigraphy. The section atop the eastern crest of Rudolf Ridge averaged 90.95 per cent CaCO3, 6.86 per cent MgCO3, and 1.26 per cent SiO2. Within a bowl-shaped valley on the northern side of Rudolf Ridge, the samples averaged 88.77 per cent CaCO3, 9.76 per cent MgCO3, and 0.48 per cent SiO2 (Assessment Report 30711).

The Carnarvon Member consists of well- bedded, dark- grey to greyish- brown lime mudstones and siltstones with shaly, black carbonaceous interbeds. A total of 44 samples were collected from the Carnarvon Member atop Rudolf Peak, representing approximately 119.5 metres of stratigraphy. The samples were collected in one section along the top of Rudolf Ridge and averaged 93.70 per cent CaCO3, 3.22 per cent MgCO3, and 1.64 per cent SiO2 (Assessment Report 30711).

Ecowaste acquired the CMM claims, adjoining Summit Lime on the British Columbia. side of the border, from 1994 through 1997. Some claims were dropped in 1999 and some were grouped and converted to a cell claim in 2005. All of the Ecowaste claims were converted to the property of Graymont in 2007 for consistency of their British Columbia. properties. Dahrouge Geological Consulting Ltd. (Dahrouge), on behalf of Graymont, carried out a mapping and sampling program at the CMM claims in September, 2008. A complete history of the showing and area can found in Assessment Report 30711.
