WAWA, ON, Nov. 22, 2011 /CNW/ - Wesdome Gold Mines Ltd (WDO: TSX) is pleased to provide an update of drilling results from its 100% owned Mishi Mine, currently in pre-production development.
Drilling this year has focused on examining the potential to extend the currently planned pit, both to the east and west. Results are now available for the western stepout drilling. Logging, sampling and assaying of the eastern stepout holes is still in progress.
A total of 21 drill holes were completed west of the pit at 25 to 50 metre spacings. Results indicate a series of mineralized, near surface, lenses some of which display above average grades.
Highlights include intersections of:
- 18.12 gAu/tonne over 2.75 metres true width
- 5.80 gAu/tonne over 1.50 metres true width
- 3.10 gAu/tonne over 4.25 metres true width
- 5.38 gAu/tonne over 1.50 metres true width
- 1.87 gAu/tonne over 8.25 metres true width
- 7.18 gAu/tonne over 1.50 metres true width
- 7.90 gAu/tonne over 3.00 metres true width
- 1.87 gAu/tonne over 9.25 metres true width
- 4.92 gAu/tonne over 4.40 metres true width
- 2.56 gAu/tonne over 7.85 metres true width
A complete list of significant intersections is provided in Table 1 with hole locations relative to the proposed pit provided in Figure 1 (available at www.wesdome.com). Drilling to the west has extended mineralization 250 metres beyond the proposed pit limit. The 5-year pit outline is 300 metres long. To date, at least two zones display reasonable continuity. This will be confirmed with trenching in 2012.
We also look forward to receiving results from drilling to the east of the pit. This drilling, on 25 metre spacings, will define the potential of a broad zone of lower grade mineralization traced by previous shallow drilling over a distance of 300 metres.
Highlights from this previous drilling include:
- 1.25 gAu/tonne over 68.6 metres true width
- 1.01 gAu/tonne over 86.3 metres true width
- 1.81 gAu/tonne over 10.9 metres true width
- 1.19 gAu/tonne over 29.0 metres true width
- 2.06 gAu/tonne over 29.0 metres true width
- 1.43 gAu/tonne over 18.5 metres true width
- 1.51 gAu/tonne over 38.7 metres true width
A surface trace of this mineralization is provided in Figure 1 (available at www.wesdome.com). A list of significant intersections from this previous drilling is provided in Table 2.
GEOLOGICAL CONTEXT
The Mishi gold deposit strikes east-west and dips 40 degrees north. It is situated within the Mishibishu Deformation Zone, a regional shear zone which follows a mafic-felsic volcanic contact. The gold is hosted by a series of conformable, en echelon, sericite-ankerite alteration zones which carry fine disseminated pyrite. The mineralized alteration zones typically include about 10% conformable smokey quartz veinlets and lenses. It is becoming apparent that the style of mineralization is more vein dominant to the west. It is likely that a series of narrower, higher grade lenses exist here. To the east, the mineralization is broad, lower grade and more disseminated in nature.
Drilling results to date are confirming mineralization of potential economic merit extends well beyond current planned pit limits. The Company plans to confirm continuity by surface trenching and evaluate its development options moving forward in light of current strong gold prices.
TECHNICAL DISCLOSURE
The technical disclosure in this press release has been reviewed by George Mannard, PGeo. and Vice President Exploration for Wesdome and "Qualified Person" as defined by NI 43-101. Assaying is performed at the Eagle River Mine Assay office by fire assay methods on 25 gram aliquots. In addition to duplicates, replicates, standards and blanks employed by the assay office, blind blanks and standards are introduced to the sample stream by the exploration personnel. Additionally, 1 in 20 samples are shipped to Techni-Lab Laboratories in Ste-Germaine Boulé, Quebec, a certified commercial laboratory and external reference.
