Point Location Description: approximate
Location Method: Based on Assessment
Access Description: Access is south from the village of Quadeville on the Addington Road (6km) to Hyland Creek Road, a logging road which branches east to the Little-Bryan Property.
1962: H. Moriarty prospected (for copper). 1973: M. Little, J. Bryan and B. Bryan carried out diamond drilling and EM surveys and discovered graphite. 1974: M. Little, J. Bryan and B. Bryan completed 2 diamond drill holes totaling 538 ft, stripping, pitting, mapping, and ground geophysics. 1981: Little Mines Limited held the claims. 1989: Harrington Sound Resources Inc. carried out mapping, sampling, prospecting, trenching, ground geophysics. 1998: Ralph V. Stewart conducted gridding, geological mapping and sampling. 2011-2012: Standard Graphite Corp. flew TDEM covering this property and the neighbouring Malcolm Prospect and delineated 2 distinct conductors under both properties.

Oct 23, 2019 (Sheree Hinz) - The property geology is believed to consist of a southern sequence of graphitic-siliceous metasediments, gabbro, diopsidic dolomite; a central zone of calcitic and dolomitic marble and quartzite; and a northern sequence of diopsidic marble, gabbro and graphitic-siliceous metasediments. The two sequences of graphite-gabbro-diopside may represent limbs of a fold with axis trending northeasterly through the area of calcitic and dolomitic marbles and quartzite. Strikes are generally east-northeast and dips are from 60 to 80° southward.

Aug 08, 2016 (A Wilson) - Assays from L. Bryan's 1974 drilling returned the following results: hole Q-2 returned an average of 3.77% graphite over 4.18 m including 85 cm grading 8.57% graphite. Drill hole Q-l also encountered minor graphitic mineralization; one interval assayed 3.28% graphite over 0.91 m and a second interval assayed 3.64% graphite over 0.88 m. Significant trench samples from the 1989 exploration program included: 5.15% graphite over 6 m, 3.72% graphite over 22 m, 4.74% graphite over 11m and 4.93% graphite over 10 m. Graphite mineralization on the Lyndoch property is present in both clastic sediments and, less frequently, in calcitic marbles. In the calcite marble it occurs as local disseminated coarse-grained flakes ranging from trace to 2%. In the quartz-feldspar biotite gneiss it is present as both medium-grained flake and as fine-grained disseminated graphite. Associated with this latter style of graphite mineralization is up to 10% to 15% sulphide mineralization, notably pyrite and pyrrhotite. Only minor sulphides are present elsewhere on the property. Assays completed by the OGS on diamond drill core returned 0.07% Cu from drill hole Q-2. A grab sample from a pit south of drill hole Q-1 assayed 0.1% Cu, 0.02% Ni and 0.02% Co.Assays completed by the OGS on 5 of 7 trenches and from semi-massive pyrrhotite in an old pit returned up to 3.45% Cg (a calculated value: graphite as carbon = total carbon less the amount of carbon present as CO2), 772ppm Cu, 101ppm Zn all from different samples. A sample of marble was taken for whole-rock and major element oxide analyses returned high silica and X-ray diffraction analysis indicated 52% diopside, 44% dolomite, 3% calcite, 1% talc. “The white diopside-dolomite assemblage observed on the property may have potential as an industrial mineral product with or without separation of the 2 primary minerals.” (Sangster and LeBaron 2014).

Notes: Accompanied A. Dubblestein to property and examined 7 trenches. 5 of the trenches and an old sulphidic pit were sampled for geochemical analysis. A sample of marble was taken for mineralogical analysis (OFR6306).
