Advancing Canada’s newest gold district:  The Borden gold project

The Borden Gold Project is located 9km from Chapleau, Ontario within one kilometre of a major highway and close to well-developed infrastructure.

The property is situated within a previously overlooked section of Timiskaming-age metasediments in the Kapuskasing Structural Zone. The gold mineralization occurs as a broad zone of disseminated and fracture-controlled sulphides within a volcano-metasedimentary belt. The main sulphides are pyrite and pyrrhotite, with the former typically dominating. The northwest portions of the deposit are characterized by local silicification but lack lithological control and quartz veining, while to the southeast a well-developed hydrothermal system consisting of local quartz flooding and potassic alteration predominates. Higher gold grades are typically associated with the better developed hydrothermal system and quartz-flooded zones. The broad mineralized zone transects numerous metasedimentary horizons and subordinate intrusives of acidic to intermediate composition, all of which display feldspathic, chloritic and biotitic alteration.

The deposit is characterized by a persistent higher-grade core surrounded by a lower-grade envelope, evident in both the lower-grade disseminated mineralization to the northwest and the high-grade gold in the southeast. The mineralized zone is up to 120m wide, and is continuous over a strike length of approximately 3,000m and down to a vertical depth of approximately 500m.

In December 2012, a step-out hole (Hole BL12-256) discovered a thick, high-grade interval of gold which subsequently developed into an extensive high-grade zone ("HGZ") that has been delineated over a continuous strike length of more than 1km and is still open to the southeast.  The discovery hole, BL12-256, included impressive intervals of 51m @ 10.3 g/t Au. In February 2014, the highest grade mineralization observed to date was found in Hole BL14-573, including 39.0 metres averaging 16.3 g/t gold. The HGZ changed the focus of the project from low-grade, bulk tonnage to high-grade underground. These results will be included in the next updated NI43-101 report.

Since its discovery in 2010, over 586 holes, representing over 200,000m, have been drilled at Borden Gold. Significant property acquisitions along the Borden Belt have increased the potential for new discoveries. Probe currently has drills turning on the project to continue improving and expanding the resource. 

BIO: Ms Oosterman is a Professional Geologist who graduated from Laurentian University in 2002 whereupon she joined Inco Technical Services Limited exploring for Ni-Cu deposits in the Thompson Nickel Belt.  She moved her expertise to the Sudbury Nickel Camp before entering the junior mining sector exploring for Ni-Cu-PGE deposits, as well as expanding into gold and base metals exploration for various styles and models including shear-hosted gold, IOGC and paleoplacer-style gold deposits. Ms. Oosterman has extensive international experience having completed exploration and development programs in Chile, Kazakhstan and most recently Zambia.  Her expertise ranges from early project evaluation to advanced stage project execution. She is currently the Project Manager for Probe Mines Limited’s  recently discovered Borden Lake Gold Project in Northern Ontario.
