Access Description: Access is via the Godfrey-Westport Highway, called the Westport road, off of highway 38. Drive north-east from Godfrey on the Westport road, past Potspoon Lake, Bedford and under a set of power lines. Turn west, left immediately after the power lines and drive approximately 1/4 mile to a gate in a field. This gate is located on a hill with a sharp turn to the left. The deposit is located to the south of the road.

Oct 28, 2013 (C Papertzian) - Within the claim group, one of the dominant rock types and the one with the most economic interest is the coarsely crystalline Grenville marbles which were at one time carbonate shell sediments. Due to the presence of graphite within these units, it is considered that originally they were organic-rich and this organic material is now the graphite. Approximately 50% or greater of the area is underlain by granitic gneisses which appear to occur as areas of upwelling. The Grenville marbles overlie these areas of gneissic upwelling and represent the lower portions of the stratigraphic column in the area. All units appear to have been subjected to very deep burial which has produced the current metamorphic grade at the amphibolite to granulite facies. The rusty paragneisses occur in relatively narrow horizons within the larger marble-rich units. The paragneisses currently have a carbonate component which suggests that the original sediments were an organic-rich arenite. The rusty paragneisses also contain significant graphite content, sometimes exceeding 5% by weight graphitic carbon. In general terms, the claim group contains coarsely crystalline Grenville marbles which have been intruded by granitic gneiss and remobilized granitic basement rocks. The marble units are considered to be thin sequences (in comparison to marbles exposed to the west) which were at one time carbonate shelf sediments. These are likely to have been rich in organics and are now graphitic, ranging from < 1 % disseminated flake graphite up to about 10% graphite (by volume). The marble is white and contains some calc-silicates. Marble tectonic breccia also is present and contains layers and fragments of rusty and pyritic and graphitic gneisses, white pegmatite, garnet gneiss and pyroxene-hornblende gneiss. Zones of rusty paragneisses apparently occur in comparatively narrow zones within the marbles and are thought to represent more siliceous sediments. These generally do have a carbonate component. Often, the rusty paragneisses contain significant graphite content, commonly exceeding 15% graphite (by volume).

Oct 28, 2013 (A Wilson) - Graphite occurs in tabular grains and foliated patches and up to 15% graphite is observed in the host rocks. Serpentine occurs as disseminated grains. Crystals and patches of pyrite and tiny grains of amber-brown, transparent titanite are found in smaller amounts. The graphite occurs in a variety of forms ranging from disseminated to coarse flake graphite ranging from 1-3% graphite. During the trenching program, selected mineralized zones were sampled. In total 16 samples were submitted to Lakefield Research for graphitic carbon -percent C (g)assay. These sample results range from 1.01% C (g) representing a lens of marble with only disseminated graphite to a high of 17.0% C (g) representing a grab sample of highly mineralized graphitic schist at the extreme northern end of the explored area. Generally the returned assay values were in the range of 6% to 10% C (g). A 135 pound sample of flake graphite was tested in 2010. Product 1 yielded a flake graphite product with a mean size of 18.93 microns. Product 2 yielded a flake graphite product with a mean size of 26.77 microns.

Notes: The property was visited on June 15, 2001 along with the owner, the chief consultant and a member of the mines group with the ministry of Northern Development and Mines. 3 zones had been stripped. Meadow zone - 856 sq. meters. A second area measuring 185 sq. meters is located on the south side of the pasture. A third area is located north-east of the pasture and encompasses a stripped area of 4,186 sq. meters.
