Probe Mines Reaching For High Grades in Low Places

Probe’s challenge is to prove to the market and their investors that this project can do better. Continued exploration with the goal of upgrading and improving their resources is really the only logical course for the company to take at this point.
Probe Mines Limited (TSX VENTURE:PRB) (“Probe” or the “Company“) is pleased to announce that it has received results for the first five holes of the preliminary infill drilling program within the recently expanded area of the High-Grade Zone (“HGZ”) on the Company’s Borden Gold project near Chapleau, Ontario. Diamond drill holes BL14-620 to BL14-624 were received and were successful in demonstrating the presence of high-grade gold mineralization, as well as confirming the continuity of the gold mineralization, within the recently expanded HGZ drilled during the last winter program. The drilling confirms that high-grade gold mineralization, similar to that intersected in previous infill drilling programs on previously delineated areas of the HGZ, is present within the new expansion zone.
The latest 43-101 compliant mineral resource estimate has the Borden gold project :
Underground resources (2.5 g/t gold cut-off)
- 1.6 Million [email protected] 5.39 g/t gold (Indicated Resources)
- 0.49 Million ounces @ 4.37 g/t gold (Inferred Resources)
Open-pit resource (0.5 g/t gold cut-off)
- 2.32 Million ounces @ 1.03 g/t gold (Indicated)
- 0.01 Million ounces @ 0.8 g/t gold (Inferred)
By comparison, Detour Gold’s open pit resource has an average grade of about 1 g/t gold while the underground mines operated by St. Andrew’s Goldfields have an average grade of 4-5 g/t. While both of these companies have operating mines in Ontario, they have struggled with profitability. Detour Gold (TSE:DGC) has continuously posted losses since they began production while the smaller St. Andrew’s (TSE:SAS) has hovered around the break-even point for the last few years.
The infill program is designed to test the new extension of the HGZ between Sections 2050 and 2200, at 50 metre-spacing, in order to better define the high-grade mineralization. The program was successful in identifying grades similar to those observed in previously delineated sections of the HGZ between 900mSE and 2000mSE. Hole BL14-620W, on Section 2150m SE, intersected a thick zone of high-grade gold mineralization, returning an interval of 21 metres averaging 7.0 g/t Au, including a 13-metre wide intercept of 10.5 g/t Au. Significantly, the mineralization was intersected at a vertical depth of only 425 metres depth, suggesting that the mineralization is in fact shallower than previously expected. These preliminary results also suggest that continued improvement in grade is possible with continued infill drilling, the bulk of which will be accomplished during the next winter program.
The following table shows selected drill results for the HGZ expansion drilling, No top-cut was used in calculating the gold intervals, the highest grade in a single sample was 26.4 g/t in Hole BL14-621W. Depths of the mineralized zone ranged between approximately 395 and 425 metres vertical, with the exception of Hole BL14-620, which intersected mineralization at a vertical depth of approximately 620 metres. All drill widths approximate true width.

Dr. David Palmer, President and CEO of Probe, comments: “The results of the infill drill program continue to confirm the strong continuity of the high-grade gold system to the southeast. The significant intervals identified in the winter program, and improved upon in this preliminary infill drilling program, indicate a robust gold system in both grade and width that remains open to the southeast. With the potential for increasing grade and further expansion, the HGZ provides significant upside for exploration in addition to its growing momentum as a potential development project. We will be focused on advancing both aspects during the 2014-2015 seasons.“
Probe has instituted a strict quality assurance and quality control (“QA-QC”) program for the Borden Gold drill core sampling, with each fire assay furnace batch of 40 samples including two certified reference materials (standards), one blank sample and one core duplicate sample. Quality control guidelines and ongoing QAQC monitoring are being carried out by Probe personnel.
About Probe Mines:
As of writing Probe Mines is trading at $2.67, down from it’s 52-week high of $3.95. The latest resource estimate caused a bit of a stir in the news as Scotiabank analyst Mike Hocking downgraded Probe Mine’s stock to “sell” as he believed the results from its technical report only reflected a moderate grade mine, and it’s orientation is awkward for efficient mining. Probe’s challenge is to prove to the market and their investors that this project can do better. Continued exploration with the goal of upgrading and improving their resources is really the only logical course for the company to take at this point.
