Sudbury, ON – Manitou Gold Inc. (TSX-V: MTU) (“Manitou”) today reported the intersection of 53.7 kg/t Au (53,700 g/t Au) over a core length of 0.55 metres in hole KW-11-26. This hole is part of an ongoing diamond drill program at the Kenwest Property, located in the Kenora Mining Division in Northwestern Ontario.
This remarkable 53.7 kg Au per Tonne (1,566 ounces/ton) intersection in hole KW-11-26 is part of a 8.45 m wide section of quartz veining contained within a broad alteration zone in the #2 Gold Structure. This gold is located only 45 meters below surface. At such a shallow level, Manitou Gold has attractive options for development of this zone.
Hole KW-11-26 intersected 8.45 meters of mineralization averaging 4.9 g/t Au with the high grade sample cut to 50 g/t. On an uncut basis this interval averages 3,497 g/t Au. Individual assays for the 8.45 m section interval are included below.

Gold mineralization has been identified within two parallel shear zones spaced only 40 m apart. As a result of this fortunate congruity, deeper holes test both structures. The two geological structures display shearing, strong alteration, quartz veining and gold mineralization.
The location of the drill holes with respect to the #1 Gold Structure and the #2 Gold Structure are indicated on the surface plan map on the Manitou Gold website at www.manitougold.com/kenwest.html. Additional figures on the website include: longitudinal sections indicating gold intersections along both the #1 Gold Structure and the #2 Gold Structure, photographs of the gold in drill core, the gold bearing alteration zone, the gold beads from the analysis of the highest grade section of drill core, and the associated assay certificate.
Further details regarding the #1 Gold Structure and the #2 Gold Structure, which are also illustrated in a long section on the Company’s website, are provided below
#1
Gold Structure
The Big Master Mine is located along the #1 Gold Structure, where the majority of the historical mining was concentrated. Manitou Gold intersected 15.4 g/t Au over 6.1 m in hole KW-10-13 while testing the extension of the structure (see press release dated July 7, 2010). This intersection is located 800 m northeast of the Big Master shaft, well beyond the limits of historic underground mining operations. The Company recently recovered previously unknown historical records, which included underground drill results from the 183m level (see press release dated January 12, 2011). Historical drill hole assays included 9.7 g/t Au over 3.6 m in hole U-39, 12.2 g/t Au over 1.7 m in hole U-33 and 34.7 g/t Au over 2.4 m in hole U-36, all of which outline a discrete zone of gold mineralization approximately 100 m long along the #1 Gold Structure.
Drill holes KW-11-25 and KW 11-26 were designed to evaluate the zone of gold mineralization indicated by historical records. Hole KW-11-25 intersected 6.2 g/t Au over a core length of 4.1 m from 297.4 m to 301.5 m, which included seven occurrences of visible gold which assayed 21.4 g/t Au over 1.05 m from
299.45 m. The second hole of the current program, KW-11-26 intersected 12.0 g/t Au over a core length of 2.7 m at 219 m. The position of these two holes extends the limits of the zone of gold mineralization 45 metres vertically below and 55 m northeast of the zone outlined in 1947. This gold zone is now known to extend for 155 meters along strike and 45 meters down dip.
#2 Gold Structure
The #2 Gold Structure has been sparsely tested by Manitou Gold with only 7 drill holes (KW-10-01; KW-10-09; KW-10-10; KW-10-12; KW-10-14; KW-11-25 and KW-11-26) spaced along a 700 metre long interval. Hole KW-11-25, which intersected 0.8 g/t Au over a core length of 2.6 m, is located 50 m southwest and 75 m behind hole KW-11-26. The intersection in hole KW-11-26 of 3,497 g/t Au over 4.9 m (including 53,700 g/t Au over 0.55 m) demonstrates the presence of high grade gold mineralization defined by elongated “shoots”, a common feature of lode gold deposits.
Due to the extremely high grade nature of the sample of the 0.55 m intersection from 55.90 m to 56.45 m in hole KW-11-26, the following procedures were undertaken in the preparation and assaying of that sample: The entire sample was crushed and pulverized and the crushing specification was > 70% passing 6mm; the pulverized sample was then screened to 100um to produce a plus fraction and minus fraction. The entire plus fraction was assayed by a 50g fire assay gravimetric method and the undersize was assayed in duplicate by a 50g fire assay gravimetric method. Assay checks were not performed on this sample, as the entire sample was consumed in the completion of the analysis. However, the Company has retained the other half of the split core and has received the gold beads from the assay lab. Procedures for preparing and sampling are otherwise as further described at the end of this press release.
