Orca Gold Announces an Initial Resource at Galat Sufar South

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Jan. 29, 2014) - Orca Gold Inc. (TSX VENTURE:ORG)("Orca" or the "Company") is pleased to declare the first Indicated and Inferred Mineral Resource estimate at its Galat Sufar South ("GSS") prospect on its Block 14 mineral license in Sudan.

The Mineral Resource estimate, using a cut-off grade of 1.0 g/t, comprises an Indicated Resource of 22.2Mt at 1.84g/t for 1.3 million ounces gold and an Inferred Resource of 6.5Mt at 1.9g/t for an additional 400,000 ounces gold. Greater than 90% of the Mineral Resource is within 100 metres of surface.

The Mineral Resource estimate was carried out by independent consultant Nic Johnson of MPR Geological Consultants of Perth, Western Australia and is shown below at various cut off grades:

  Indicated Inferred
COG Mt Au g/t '000 Oz Mt Au g/t '000 Oz
0.2 74.6 0.90 2,170 30.5 0.8 748

The Mineral Resource has been estimated using the results of 35,637 metres of drilling (4,093m of diamond drilling and 31,544m of reverse circulation drilling) completed between November 2012 and December 2013.

Mineralisation is hosted by intermediate intrusives and volcaniclastics and is associated with intense quartz-sericite-carbonate alteration and pyrite. Drilling has focused on two distinct areas:

  • The Main Zone consists of N-S and N-W trending mineralized bodies with a combined strike length of 550m and has been drilled to an average depth of 150m below surface (max 250m). The Main zone remains open on strike and at depth.
  • The East Zone (400m east of Main Zone) comprises mineralisation in several sub-zones within an area of 800m by 300m with the primary trend extending over a strike length of 435m. It has been drilled to an average depth of 140m (max 330m) and remains open to the north and east.

Mineralisation in both areas is notable for the width and consistency of gold mineralisation with true width in the Main Zone exceeding 90m in some sections and in the East Zone frequently exceeding 60m.

Approximately 19% of the Indicated Mineral Resource comprises oxidized material (18% of Inferred Mineral Resource) at a 1.0g/t cut off as detailed below:

    Indicated Inferred
Zone   Mt Au g/t '000 Oz Mt Au g/t '000 Oz
Main Oxide 1.6 2.37 121 0.2 1.7 12
Transition 1.7 2.28 126 0.1 1.9 5
Fresh 4.7 2.10 318 1.6 2.3 116
Total 8.0 2.19 565 1.9 2.19 133
East Oxide 3.2 1.64 166 0.3 1.6 14
Transition 2.2 1.64 115 0.1 1.4 6
Fresh 8.9 1.63 464 4.2 1.8 249
Total 14.2 1.63 746 4.7 1.8 269
  Total 22.2 1.84 1,311 6.6 1.9 402

Orca has conducted initial metallurgical testing on four drill core and three RC chip composite samples. Results from direct leach testwork suggest recoveries ranging from 85-89% in the East Zone (oxide, transition and fresh) and 79-95% in Main Zone Fresh material. Fast leach kinetics were observed and for all samples reagent consumption was relatively low. Further diagnostic leach testwork is ongoing.

The 400 metre gap area between the Main and East Zones remains substantially untested and Orca will now focus on exploration of extensions to the resource and on targets within a 5km radius of the resource.

Orca has now been working in Sudan for over three years and enjoys an excellent working relationship with the Geological Research Authority of Sudan ("GRAS") and Ministry of Mines. The Mineral Resource at GSS is the first major gold discovery in Sudan by a North American company, validating Orca's investment decision and cementing its first mover advantage. With Centamin Egypt's +15 million ounce Sukari Mine, located to the north of GSS in Egypt, Orca's Resource confirms the exciting potential of the Arabian-Nubian Shield.

Simon Jackson, President and CEO, said, "The release of the Mineral Resource at GSS is a milestone event for Orca. The size and grade of the resource illustrate the great potential of Sudan to host significant gold deposits and we look forward to results of ongoing exploration aimed at increasing our resource inventory at Block 14. The robust resource supports our original objective of finding a deposit that is capable of becoming a commercial mining operation, and we believe that GSS continues to show signs that it has real potential to fulfill that objective. We are extremely happy with our decision to invest in Sudan and Block 14 and are excited by the future prospects for the Company."
