Point Location Description: General

Location Method: Conversion from MDI

Access Description: Property access is well provided via Highway 594 west from Dryden and then south along Highway 502, which diagonally crosses the property from northwest to southeast. A direct water route to the towns of Wabigoon, Dinorwic and Dryden is provided via Minnehaha Lake, Crooked River, Dinorwic Lake and Wabigoon Lake.

Exploration History

1980: The Starr showing was discovered by prospector E. Starr, while examining road cuts along newly constructed Highway 502. 1982: A native gold showing was found on the east side of the highway on the Starr property. The showing was examined by J. Patrick Sheridan and optioned; subsequently examined and prospected by James Vernon and Philippe Roby. 1983: A total of 299 feet were drilled in 10 vertical, percussion holes.

Geology Comments

Mar 09, 2010 (J Bongfelt) - The area is underlain by thick sequences of metavolcanic and metasedimentary units intruded by mafic sills, lamprophyre dikes, quartz and feldspar porphyries and granitic rocks marginal to a batholithic dome. The rocks are predominately Archean with the exception of a series of Proterozoic diabase dikes. The main structural features in the area are the northeast trending Manitou Straits Fault which bounds the Starr property to the southeast and the tightly folded Manitou Anticl ine, the axis of which passes through the centre of Sasakwei Lake.

Lithology

Lithology Comments

Mar 09, 2010 (J Bongfelt) - Non-porphyritic, fine grained mafic pillowed metavolcanics (unit lc) occur in three zones, the largest located roughly south of Highway 502 between TL 11W and Sasakwei Lake. Here the pillows are small to medium (averaging 0.5 wide), irregular, elongate, with increasing stretching and flattening parallel to foliation as the anticlinal axis is approached. Where shearing is strongest (as along the western shore of Sasakwei Lake) these rocks resemble coarse volcanic breccias due to fragmentation of selvages and pillow cores. However, the remnants of distintive light green epidotic pillow centres, often containing subparallel fractures, appear diagnostic for the presence of pillows regardless of deformation. These fine grained non-porphyritic pillow basalts host the Starr showing and many good exposures can be seen along Highway 502 in that area. (Kenora AF 52F10SE Z-4, Asamera Inc., p.8 of report)

Mineralization

Mineralization Comments

Mar 09, 2010 (J Bongfelt) - 1982 Eugene Starr found a spectacular gold showing on the east side of the highway on the Starr property (a new high grade occurrence of visible gold). Samples, located in the head office in Toronto, are estimated to range upwards of 500 ounces of gold over two inches. Ten short percussion holes (totalling 100m), drilled under the showing, showed only minor gold mineralization, however, one surface sample located approx. 50 feet east of the original showing returned some high-grade gold. (Kenora AF 52F/10SE EE-3, STARR, Eugene) 1983 (Asamera) Three holes (199.6 m) tested the Starr quartz vein/shear plane at 25m and 30m downdip, directly below and 25m to either side of the showing. Competent, moderately chloritized, fine grained massive and pillowed metabasalts were cut by all three holes. A sheared, strongly chloritized zone containing abundant quartz sweats occurred in DDH 5T83-2 from 13.0 m to 16.5 m downhole, but this assayed only trace amounts of Au. Pyrite occurs locally up to 10% or 15% in all holes. Pillow cores are light green, 10 to 50 cm wide and bounded by thin dark green fine grained selvages. A silver assay of 1.46 oz/ton over 20 cm was obtained in DDH 5T83-3 at 28.9 to 29.1 m in a carbonate-quartz veinlet. (Kenora AF 52F/10SE Z-4, Asamera Inc., Starr Prospect Report, p.14)
