Omai Gold Mines Corp. has released an updated mineral resource estimate on its 100%-owned Omai gold property in Guyana. The property hosts two gold deposits, the shear-hosted Wenot deposit and the adjacent intrusive-hosted Gilt Creek deposit. This updated mineral resource estimate includes an expansion to the Wenot mineral resource which was announced January 2022, and incorporates the Gilt Creek deposit that lies below a former pit that produced 2.4 million oz gold. Together, these deposits contribute to a more than doubling of the company’s mineral resource estimate on the Omai property.

Omai mineral resource estimate update highlights:

  • 1 907 600 oz gold (Indicated) mineral resource estimate (MRE), a 171% increase over the January MRE of 703 300 oz.
  • 1 777 600 oz gold (Inferred), an 89% increase over the January MRE of 940 000 oz.

The MRE includes:

1) Gilt Creek deposit

  • Newly introduced into the company’s MRE, hosted within a 500 m by 300 m quartz diorite intrusive stock.
  • Located 500 m north of the Wenot deposit and below the past-producing fennell pit.
  • 1 151 000 oz gold (Indicated) at a grade of 3.22 g/t Au.
  • 665 000 oz gold (Inferred) at a grade of 3.35 g/t Au.
  • For the purposes of this MRE, an underground mining approach is applied.
  • Open to depth and holds potential for lateral expansion.

2) Wenot deposit

  • Updates the initial MRE for Wenot, announced only nine months ago in January 2022.
  • 756 600 oz gold (Indicated), an 8% increase over the initial January 2022 MRE.
  • 1 112 600 oz gold (Inferred), an 18% increase.
  • 1.34 g/t Au grade of Indicated MRE, a 2% increase.
  • 1.72 g/t Au grade of Inferred MRE, a 15% increase.
  • For the purposes of this MRE, a constrained pit approach is applied.
  • Excellent exploration potential along the Wenot shear corridor that hosts this deposit.

Elaine Ellingham, President & CEO commented:

“We are extremely pleased with the results of this updated 2022 MRE. In addition to more than doubling our NI 43-101 MRE in nine months, we were able to accelerate and exceed our goal of bringing the Gilt Creek Gold deposit and a Wenot deposit expansion into the company’s MRE before year end 2022.”
