Exploration History

1931: R.S. Sheppard discovered a number of auriferous veins in the area and in the following year the property was optioned to the West McWatters Syndicate who continued prospecting and trenching the property. 1935: Buffalo Ontario Gold Mining optioned the property but what exploration took place is unknown. 1938: Buffalo Shepmac Gold sampled and drill tested a number of veins on the property. Three holes were completed in the area of the #1 and #2 veins and several quartz veins were intersected carrying gold values up to 0.9 g/t. 1973: Park Precious Metals carried out an IP survey to the north of the #1 and #2 veins and in a drill hole 150m (500 - 600') west of the trenches intersected two short intersections with weighted averages grading 53 g/t Au, 50 g/t Ag, and 1.0% Cu over 1.2m (1.56opt Au, 1.47opt Ag, 4.2'). 1981: Stralak Resources carried out a geological appraisal of the property but it is unknown if any exploration took place. 1982: Jarvis Resources acquired the property and over the next two years carried out VLF electromagnetic survey, a bulk sampling program on the #6 vein, collected muck samples on the #10 vein and drilled 27 holes on a number of different veins. 1984: Chester Minerals Limited – EM, Mag. 1987: Canorth Resources carried out a program of prospecting, geological mapping, stripping, trenching and VLF electromagnetic, magnetic and IP geophysical surveying. This work was followed in the next year by a nine hole drill program to test a number of veins in the area for a total of 629m (2064 feet) combined with some petrographic and lithogeochemical studies. Core from one vein returned values of 8.9 g/t and 3.3 g/t Au over 0.9m and 0.5m respectively, the other vein was cut off by a diabase dyke. 2009: Trelawney Mining and Exploration Inc. – IP, Mag, RES. 2010: Trelawney Mining and Exploration Inc.- AEM, AMag. 2011: Trelawney Mining and Exploration Inc. – DD – 10 – 6037m.

Lithology

Lithology Comments

Dec 07, 2005 (K Houle) - The mineralization is hosted in a leucocratic tonalite with roughly equal amounts of quartz and plagioclase. Biotite is the main mafic mineral with minor amounts of clinopyroxene. Magnetite and chlorite occur in minor amounts as an in situ alteration product of biotite. Chlorite also occurs as fracture and vein fillings. Sericite alteration of the plagioclase is much more widespread but more intense near the shears together with a patchy development of biotite. Near the mineralized zone the rock is marked by a grain size reduction, abundant sericite and carbonate in the rock matrix. Trace amounts of hematite occur in these sheared tonalites.

Mineralization

Mineralization Comments

Dec 07, 2005 (K Houle) - Mineralization is associated with a quartz veins and altered shear zones. This mineralization is predominantly massive and semi massive pyrite with traces of chalcopyrite and sphalerite in quartz veins. Adjacent to the veins there are disseminated fine grains of pyrite and less abundant chalcopyrite. The other sulphides that have been reported from this occurrence occur erratically in trace amounts.

Dec 07, 2005 (A Wilson) - Gold analyses for diamond drilling conducted in 1938 were up to 0.9 g/t Au. Weighted averages from trenching completed by Park Precious metals were 53 g/t au, 50 g/t Au and 1% Cu over 1.2m. Core from one vien drilled by Canorth returned values of 8.9 g/t Au over 0.9m and 3.3 g/t Au over 0.5m. Grab samples collected by the OGS in 1993 returned values of 9.19 g/t Au, 6.8 g/t Ag; 19.2 g/t Au, 21.7 g/t.

Geologist: W Savage

Notes: The Sheppard showing in the northeast corner of claim S-20655(P) which was opened up by the West McWatters Syndicate, is located close to the shore in the most westerly bay of the centre lake of the Three Ducks Lakes. Several pits and cross trenches were put down in a rusty fracture zone about two feet wide which strikes N080W and dips 50 to the north. Irregular stringers of quartz with pyrite occur within the fracture zone. The country rock is a blocky grey granite. In a parallel trench about 50 feet to the south rusty stain can be seen across a width of four feet. This trench was filled with rubble. [ PRECIS ]

Date: Aug 16, 1993

Geologist: K Houle

Notes: Veins #1 | #2 are parallel and approximately 20m apart. Both veins were found to be stripped and trenched/pitted. Vein #1, the southern trenched area, consists of parallel sets of < 1-2cm qtz veins in cross-cutting a medium grained granodiorite. The granodiorite exhibits weak fabric at 170 deg AZ with a dominant fracture set at about 120-130 deg. Sulphides occur as semi massive and disseminated pyrite 1-5% and trace sphalerite associated with the quartz veining, small shears and margins of wall rock. Vein #2, the northern trenched and pitted exposure, consists of quartz veining associated with a shear in diorite. Outcrop has a 3x3m water filled pit in the west end and has an overall rusty gossanous appearance proximal to the shear. Mineralization is predominantly disseminated pyrite and trace chalcopyrite with occasional semi massive pyrite associated with 1-3cm grey quartz veining. Shear/veining in both locations has been found to strike at 270 deg and dip to the northeast 65-70 deg.
