Access Description: Point Located: A point 2.00 km north and 0.59 km east of the southwest corner of Tannahill Township.
1931: V. Jordan staked claims in southwest Tannahill Township for Teck Hughes Mines Ltd. following the discovery there of free gold in quartz stringers. 1932: Before the claims lapsed, pits and trenches were excavated and an access road was cut. 1935: Claims in the area were restaked by J.A.M. McClosky for Erie Canadian Mines Ltd. 1936: Four trenches and a pit were excavated on a northeast striking mineralized zone. 1937: Claim nos. 26639-26644 were patented by A. White. 1981: P. Crossan excavated 105 feet of trenches, blasted 3 pits, and diamond drilled 1 hole totalling 35 feet. 1985: T. Obradovich completed electromagnetic and magnetic surveys. 1988: W. Golden and T. Obradovich completed magnetic and electromagnetic surveys. 1996: Otis J./Pacific Mariner completed linecutting, magnetometer and limited IP. The company changed their name to Abitibi Mining Corp. and Sedex Mining Corp. respectively. 1996-1997: Sedex and Abitibi completed 44 diamond drill holes totalling 6583 m, trenching, sampling and a soil geochemical survey. Mineralization is associated with qtz, carbonate, albite, pyrite alteration in 2 zones with assays generally less than 2 g/t Au and widths to 11.0 m.

Dec 07, 2005 (C Salo) - Geological mapping (Jensen 1982, 1978, 1971; Jensen and Langford 1985; Jensen and Baker 1986; Johnstone and Steele 1989; Baker et al. 1982; Steele 1988) indicates that the occurrence area is underlain mainly by largely glacial drift covered hornblende hornfels facies (Archean) Blake River Group metavolcanic rocks and porphyritic syenodiorite dikes.

Sep 19, 2008 (C Salo) - Near the no.3 post of claim no. 26639, auriferous quartz-(calcite?) veins are reported (assessment files, Resident Geologist's Office, Kirkland Lake) to be exposed along the contact of a northeast striking and steeply south dipping porphyry dike which intrudes volcanic rocks and which is associated with shears which strike 045-070 and dip about south 60 degrees. Where exposed in pits and trenches, these shear/fracture zones are reported to be as wide as 10 feet and are reported to host quartz veins and associated anomalous fine grained pyrite mineralization. The veins are reported to range in width from 3.17 mm to 5 cm and to follow the shears along about 200 feet of strike. The veins are described (assessment files) to be narrow but persistent and to contain free gold. Reported gold assays from quartz vein material range from trace to 0.05 ounce of gold per ton. West of the quartz veins, a 45.7 cm wide mineralized (i.e. pyritic?) porphyry dike striking east southeast and dipping north 15 degrees is reported (assessment files) to be traceable for about 800 m. Reported assays from this dike range from 0.33 to 0.85 ounce of gold per ton (Jensen 1971). from assesment file KL-4624 The Tannahill project is underlain by a wide sequence of calc-alkaline flows of predominantly basaltic and andesitic composition. The flows are generally massive, pillowed, or flow brecciated. Locally the flows are massive with a crystalline texture, and resembles a gabbroic intrusion. A large coarse grained syenite intrusion is situated in the southern portion of the project. A number of narrow syenite dykes radiate outwards from this intrusion, crosscutting stratigraphy. The syenite intrusion and the associated dykes are strongly magnetic and provide the only magnetic contrast in the volcanic sequence. Drilling to date on the Tannahill Gold Zone has identified two close spaced parallel highly prospective north dipping gold bearing structures (2nd order structures) related to a large vertical structure (1 st order structure). The gold bearing structures (Lower Zone and Upper Zone), consist of pervasive quartz-carbonate-albite alteration with S-10% disseminated pyrite with variable quartz veining. Gold is hosted in sections of the pervasive alteration which contain greater than 507o quartz veins. The zones strike in a northeast/southwest direction and dip to the north at 60". The Lower Zone has returned the higher gold grades to date, including visible gold in four holes, and holds the greatest exploration potential. The Lower Zone shows continuity along strike and consistency in grade. It has been successfully intersected along 300 metres of strike length at the 25 and 50 metre levels, and may remain open in both directions. Grades and widths above the 50 metre level are generally 0.35 - 3.25 gm/t over widths ranging between 0.60-3.0 metres. At depth the zone widens significantly and the grades increase dramatically (Figure 2). Three holes below the 75 metre level along 100 metres of strike length have excellent widths with high gold grades (5.16 gm/t 1 5.0 metres in T-96-9, 4.80 gm/t 1 5.00 metres in T-96-11, and 7.02 gm/t 1 3.7 metres in T-96-15). The Lower Zone intersects the 1 st .order vertical structure at approximately the 125 m vertical level. Gold mineralization has been identified in the 1 st order vertical structure, however grades and widths are generally sub-economic.
