Access Description: The Straw Lake - Centre Lake (Pit 5) property is located in Northwest Ontario on N.T.S. 52 F/3. Straw Lake which is central to the property is approximately 65 kilometres due north of the Town of Fort Frances and 81 kilometres southwest of the town of Dryden. The property is accessible year round by car/truck either south from Highway 17 at Dryden or north from Highway 11 on Highway 812 to Cedar Narrows Road. Cedar Narrows Road is a well maintained gravel road which bisects the Straw Lake property. The northeast arm of Straw Lake, and the exploration camp are at km. 42 of Cedar Narrows Road.

1933-41 The Straw Lake Beach Gold Mines Syndicate: Formed in 1934 to explore and develop a gold occurrence discovered by Murdock Mosher and Fred Grozelle on the southeast shore of Straw Lake in 1933. The Straw Lake Beach Mine, became the second largest past-producing gold mine in the Kenora District. The production history of the Straw Lake Beach Mine is as follows: 1938-41 11,568 oz Au from 33,662 tons (0.34 oz/ton) 1,049 oz Ag. Workings consisted of a shaft to 723 feet with 6 levels and 4,631 feet of lateral development. 1969 Canadian Nickel Company: Drilled at least two holes in the area covered by the present claim group. CANICO drill hole 42727 intersected 11 feet of graphitic mafic volcanic (Sparton anomaly 1.16). CANICO drill hole 32897 cut 105 feet of overburden and 26 feet of meta-dacite. No conductor was intersected. This hole is in the general vicinity of Sparton anomaly 3.15. 1970 Freeport Canadian Exploration Co.: Completed a Questor Input survey in May 1970, which covered the present Straw Lake property. Follow-up consisted of ground EM and magnetometer surveys and drilling. At least 6 drill holes were completed on the present property. All holes intersected graphitic slate or graphitic shear zones. 1976 Mindel Mines Ltd.: In July and August following a period of surface exploration to re-establish the old Straw Lake Beach Mine showings relative to the underground workings, Mindel drilled a total of 2,917 feet in 3 deep holes to test below the centre, east end, and west end of the mine workings. Low values were encountered in the first two holes. (Assessment File 52F/03 NW N-2, Sparton Resources; Straw Lake Project Summary Report 1983 Exploration Program, Kenora Resident Geologist Office)

Feb 22, 2010 (C Ravnaas) - Geological mapping during the 1983 field season was completed on the western grid and grid sheets 1-3. These sheets correspond to L-O to L-28W on the western grid and L-26W to L-32E on grid sheets one to three. The general geology of the Straw Lake Area in the simplest terms is characterized as a greenstone belt lying between the Jackfish Lake-Weller Lake Pluton and the Lawrence Lake Batholith. Rock types are mainly interlayered, steeply dipping to vertical ,mafic, intermediate and felsic metavolcanics, with intercalated metasediments. Distinguishing between crystal tuffs and metasediments is often difficult, especially where foliation and shearing are intense. A quartz-feldspar porphyry sill intrudes the volcanics and is identified physiographically as a ridge of resistant rock. Felsic intrusives (i.e. granites & rapikivi) occur at or near the contacts with the batholiths and near the Manitou fault.
