Mining’s old guard needs strong medicine
A new report details subpar investor returns in the mining industry over the last decade, particularly big cap diversified companies which have not adapted to new realities.
VANCOUVER, BRITISH COLUMBIA–(Marketwire – Aug. 9, 2011) – Bayfield Ventures Corp. (TSX VENTURE:BYV) (FRANKFURT:B4N) (the “Company”) is pleased to announce additional gold and silver intercepts on its 100% owned Burns Block property in the Rainy River District of north-western Ontario. The Burns Block is situated adjacent to the east and on strike to Rainy River Resources’ (TSX-V: RR) multi-million ounce gold deposit.
Rainy River’s latest NI 43-101 resource calculation shows a measured and indicated resource of 4.41 million ounces of gold, averaging 1.17 g/t gold, in addition to an inferred resource of 2.33 million ounces of gold, averaging 0.94 g/t gold. Rainy River considers that the material above the final depth of the conceptual pit shell (450 metres vertical depth) offers reasonable prospects for economic extraction from an open pit using a cut-off grade of 0.35 g/t gold (June 29, 2011 by SRK Consulting (Canada) Inc.).

Highlights:
Discussion of Results:
A wide, near surface, zone of gold and silver mineralization has been intersected in drill hole RR11-119 which is located 45 metres southeast of the collar of high grade hole RR11-71 along the Far North Drill Fence at the Burns Block. The 22.5 metre interval of 2.95 g/t gold equivalent in RR11-119 starts at 58 metres down hole or approximately 48 metres vertically below surface given the 60 degree inclination of the drill hole.
The mineralization is hosted within the main foliated and sheared zone or envelope that extends onto the Burns property from the main ODM17 gold-silver deposit of Rainy River Resources directly to the west. The intercept in hole RR11-119 lies outside to the east of the zone encompassing the southwest plunging series of high grade gold-silver intersections discovered by Bayfield at the Burns Block. Whether this intercept represents a fault offset portion of the partially delineated high grade zone to the west, or whether it is a separate zone is not known at the present time. A detailed compilation of logged structural data is underway to try to improve the understanding of the mineralization and to help in the targeting of additional drilling in the area.

Bayfield is also pleased to report success on the central fence drilling as additional discoveries of mineralized gold-silver intervals are being made in the west-central portion of the Burns property. Holes RR11-63 and RR11-68 were drilled from a common collar position 20 metres southeast from the collar of hole RR11-14. Previously reported hole RR11-14 had a high grade zone of 3.0 metres grading 11.44 g/t gold equivalent at a depth of 275 metres down hole. This recently discovered zone is 60 metres east of the known high grade zone on the western portion of the property. As was mentioned in the highlights above and as displayed in the table below both RR11-63 and RR11-68 intersected significant mineralized zones containing multi-gram gold and silver values over approximately 7-10 metre intervals. We are waiting on assays from additional step-out holes completed further east along strike.

* g/t = grams per metric tonne
* AuEq (gold equivalent) values calculated at a 45 to 1 (gold price vs. silver price) ratio and metallurgical recoveries and net smelter returns are assumed to be 100%
* The intervals were determined using a 0.35 g/t gold equivalent cut-off grade with a maximum gap of 3.0 metres between intervals below the cut-off grade
Current Exploration Summary:
Bayfield is still at an early stage of exploration on its Rainy River properties with approximately 50,000 metres of drilling completed out of the planned 100,000 metre drill program. However, due to the backlog of pending assays at the labs, approximately 40,000 metres have been announced with the additional 10,000 metres still pending.
| Assays | Specific Hole Numbers | Holes Pending | Total Metres Pending |
| Partial Assays | RR11-61/65/66/69/72/73/74/76/78/79 | 10 holes | 2267.00m |
| No Assays | RR11-85 to RR11-132 (excluding RR11-119) | 47 holes | 10870.45m |
| Total | 57 holes | 13137.45m |
This latest batch of results reported above illustrates strong gold and silver mineralization intersected in step-out holes to the east of the high grade shoot on the western portion of the Burns Block. Follow-up drilling is planned for these newly discovered zones as well as expansion drilling further to the east and additional definition drilling of the known high grade zone to the west.
Quality Assurance:
Drill core analysis and assaying is being conducted by ACT Labs in Thunder Bay, Ont. The lab is ISO/IEC 17025:2005 (CAN-P-4E) certified. The drill core is split and sampled in standard 0.5 metre to 1.5 metre intervals. The core samples were analyzed for gold by 30-gm fire assay with AA finish and by gravimetric methods from assays over 5,000 ppb (over limit). Screened total metallic assays are being performed on samples assaying over 5,000 ppb. The core samples were analyzed for silver by Ag Aqua Regia-ICP finish and Ag Fire Assay-Gravimetric from assays over 100 ppm (over limit). The Company has implemented a quality assurance and quality control program to ensure that the sampling and analysis of all samples is conducted in accordance with the best possible practices.
