Fennell Pit

The Fennell pit mined the upper portion of an irregularly shaped pluton referred to as the Omai Stock.  Gold mineralization is found associated with a series of widespread quartz-carbonate veins and stringers which have a number of orientations.  These occur within the Omai quartz diorite stock as well as into the surrounding country rocks.  The Omai Stock has been the focus of gold exploration and production at Omai for over 100 years.

During its operation, 2.4 million ounces of gold were produced at an average grade of 1.6 g/t Au to a maximum depth of 250m.   Mining at Fennell bottomed at a barren diabase sill.    After mining had ceased in 2005, exploration drilling discovered that the stock continues below the sill, to a depth of at least 960 meters with gold mineralization similar to that mined in the Fennell pit.  Forty-six holes were drilled to test below the sill and the deepest drill holes ended while still in gold mineralization.  At the Aurora Mine, approximately 200 km to the northeast of Omai, their Rory’s Knoll gold deposit, that is said to be similar to our Omai stock, is now known to extend to a depth of 2 kilometers.

Significant Mineralization below the Fennell Pit

A significant mineralized zone was confirmed under the Fennell pit in 2007.  We plan to drill test this area in the first half of 2022 with the objective of upgrading and verifying the mineralized zone and then continue to explore the depth potential of this deep rooted Omai stock.  Based on the known gold mineralization identified in the 46 drill holes and our knowledge of this Omai stock, we believe there is good potential for this mineralization to continue to significant depths.

  • Fennell gold mineralization hosted in a 400m diameter quartz diorite intrusive – the “Omai Stock”
  • Production of 2.4 million oz Au above the sill ~9600 oz per vertical metre
  • Pit bottomed at 250 m in a barren ~180m thick diabase sill
  • 2006-07 Iamgold dewatered the pit and drilled ~27,000 meters in 46 holes
  • Discovered high-grade gold mineralization down 650 m below the sill; deepest hole to depth of 967 metres ended in mineralization
  • Impressive intersections:
    • 41 intervals > 34g/t Au over 1m
    • 3 intervals 1000 to 3350 g/t Au
    • 143m @ 2.6 g/t Au over 1 m
