Potential for Large Tonnage Increases
In Zone 3 of the Drayton-Black-Lake project, Heritage Mining (WKN A3DTM6 / CSE HML) has discovered a new type of gold mineralization during its recent drilling that had not been encountered on the project before. It is an intrusion-related gold mineralization primarily contained within a granitoid.
In the past, exploration at Drayton Black Lake focused on discovering orogenic gold contained in the greenstone country rocks surrounding the extensive granitoid areas. However, recent drilling in Zone 3 intersected mineralization primarily contained within a granitoid and exhibiting a multi-element geochemical signature. These elements include coeval intrusion sequences and vein morphologies consistent with the intrusion-related gold model.
These exciting results were confirmed by Dr. Gregg Morrison, an expert in intrusion-related mineral systems. The identification of intrusion-related gold opens up additional significant discovery potential for Heritage Mining in geological formations of the Drayton-Black-Lake project that were previously not explored for gold.
The Exploration Strategy Changes Overnight and the Exploration Potential Grows Enormously
These findings represent a breakthrough for the project’s development, as this new type of mineralization opens up considerable potential for large-volume, easily mineable deposits. For Heritage Mining, the exploration strategy has fundamentally changed almost overnight. Advised by Brett Davis and Dr. Gregg Morrison, Heritage Mining is well-positioned to now unlock further opportunities and significantly increase the project’s value.
At Drayton Black Lake, Zone 3 is located in the favorable contact zone between a granite intrusion (Lake of the Bays Batholith) and the mafic metavolcanic rocks of the Sioux Lookout Greenstone Belt. Gold mineralization has been identified in both rock types. However, the gold is predominantly contained within the granite. This granite can be described as a quartz-feldspar-biotite body overlain by a well-developed tectonic foliation and has a diameter of at least 30 kilometers in plan view.
With the recent drilling program, Heritage Mining only tested a strike length of 200 meters within the contact zone. The drilling intersected feldspar pegmatite veins that predominantly run through the granite. These pegmatite veins form a layered arrangement above the batholith contact with the mafic host rock and resemble the granite in appearance.
The new findings are particularly significant because it now appears possible to confirm large tonnage deposits. This has significantly increased the project’s exploration potential. In a next step, Heritage Mining now plans to conduct closely spaced magnetic and IP ground surveys. These are intended to define the favorable granitoid-metavolcanic contact and zones of disseminated sulfides in quartz veins. This data will subsequently be crucial in planning and conducting further drilling programs on the project.
