Point Location Description: Shaft
Location Method: Data Compilation
Access Description: The property is located in the Tashota area, 3.2 km south of the former C.N.R. Tashota station. The property is accessible by travelling 7 km east of Jellico on Highway 11 and then north on Abitibi's Camp 40 Road to the former Camp 40 site. Continue north on the Auden Road to within approximately 6 km of Auden. Take the right fork in an east-northeasterly direction toward Tashota. A winter drill road covers the final 2.5 km north to the Canadian National Railway and Tashota. There is a trail south from Tashota to the Adair occurrence. Or, a clearing at the shaft allows landing of a helicopter. An alternative route to the area involves branching off the Camp 40 Road to the Con Creek Road. One drives a connecting Buchanan Bros. cutting road terminating north of Gzowski Creek, northeast of Metcalfe Lake. The Adair shaft is less than 3.0 km cross-country north-northwest of the road end.
1924-25: George H. Adair discovered gold along Tashota Creek approximately 3.2 km south of the CNR station at Tashota. Channel, grab and chip samples and trenching were performed on six claims. A 7.9 m shaft was sunk in a quartz vein on claim KK990. 1929-30: Shaft deepened to 20 m. 1934-37: Tashota Creek Gold Mines Ltd. completed stripping, sampling, road cutting and erection of buildings. 1944-48: Invaday Mining and Exploration Co. Ltd. incorporated and controlled the 6 Adair claims. 1961: 4 diamond-drill holes totalling 167.3 m were bored. No encouraging results. 1965: V. Feely and D. Seppa conducted a self-potential survey as well as ground mag. Several anomalies were located, but apparently not followed-up on. 1973: W.J. Cummer performed geological and mag surveys on the Adair property. 1976: Cameron M. Ross performed manual and mechanical work. 1982: John Koski restaked the Adair property and the claims were transferred to Teck Exploration Ltd. 1983-84: Linecutting, mag and EM surveys were performed by Teck Exploration Ltd.

Dec 07, 2005 (G White) - The Adair Occurrence is located in the north central portion of the Onaman-Tashota metavolcanic belt. Amukun (1977) described the geology at the Adair property as follows: 'The mineralized quartz veins of the area are injected into highly sheared mafic to int. metavolcanics (and derived chlorite schist) which are extensively intruded by swarms of narrow quartz and /or feldspar porphyry dikes and derived quartz-sericite schist. At the western end of the property is an intrusive contact between the metavolcanics and derived schist, and the Elbow Lake Stock.' Quartz biotite schist are interpreted to be a highly altered equivalent of the mafic metavolcanics. Disseminated pyrite is present in the shear zones within the quartz biotite schists. Amukun (1977)also stated: 'The metalliic minerals associated with the gold in the veins and identified in the field are: pyrite, pyrrhotite, chalcopyrite, galena and sphalerite. When the shaft was sunk in 1925, it exposed a vein of quartz 2.0 feet wide extending downward for 5.0 feet, and carrying over an ounce in gold, and also a quartz vein about 3.0 feet wide, widening out to 4.0 feet at the 25-foot level. Channel assay results gave over 9 ounces per ton gold (Halstead 1947) and silver. Other grab and chip sample results from the surface and underground workings returned encouraging values of gold and silver.' In 1931, 34 tons of gold ore were milled and 15.12 ounces of gold and 6.0 ounces of silver were recovered.
Dec 07, 2005 (B Nelson) - The mineralized quartz veins of the area are injected into highly sheared mafic to intermediate metavolcanics which are extensively intruded by swarms of narrow quartz and / or feldspar porphyry dykes and derived quartz-sericite schist. The rocks in the vicinity of the shaft consist of pillow lava, chlorite schist, quartzs sericite schist, porphyry dykes and gabbro, all with a foliation of north 25 degrees east, and a dip of 75 to 85 degrees east. At the western end of the property is an intrusive contact between the metavolcanics and derived schists and the Elbow Lake Stock. The metallic minerals associated with the gold in the veins and identified in the field are pyrite, pyrrhotite, chalcopyrite, galena and sphalerite. When the shaft was sunk in 1925, it exposed a vein of quartz 0.6 m wide extending downward for 1.5 m, and carrying over an ounce in gold, and also a quartz vein about 0.9 m wide, widening out to 1.2 m at the 7.6 m level. Leigh (1973) described gold occurring in narrow quartz veins associated with rusty weathering shear zones in quartz biotite schists which in turn are intruded by numerous feldspar porphyry dykes. Four drill holes directed at possible extensions of the zone intersected irregular sulphide mineralization and apparently nil to trace gold values.

Dec 07, 2005 (B Nelson) - During 1931, 34 tons of gold ore were milled and 15.12 oz of Au and 6.0 oz of silver were recovered. Leigh (1973) collected 17 large chip samples from the rusty shear zones and quartz veins. One sample assayed 0.02 oz/ton Au and the remainder assayed trace to nil.
