Orca Gold Inc. (TSX.V:ORG) is pleased to announce an updated Mineral Resource Estimate for the Company’s Block 14 Gold Project in the Republic of the Sudan. This estimate will form the basis for the Feasibility Study due for delivery in November this year.

Highlights

• The Mineral Resource Estimate of the Galat Sufar South (“GSS”) and Wadi Doum deposits comprises an Indicated resource of 79.9Mt grading 1.30g/t Au for 3.342 Moz of gold and an Inferred resource of 18.5Mt grading 1.2g/t Au for 0.711 Moz of gold (at a cut-off grade of 0.6g/t)
• The increase in Indicated resources will directly impact the Estimate, which will form the basis for the Feasibility Study due for release in November 2018
• Notable intercepts from the 2018 resource expansion drilling program include (*previously released):

• The highlighted intercepts demonstrate a higher-grade core within both the GSS and Wadi Doum deposits. It is anticipated that this will result in the mining of higher grades in the early years of the project, significantly impacting economics
• The latest Mineral Resource Estimate is based on 111,761 metres of drilling in 756 holes

Mineral Resource Estimate

The Mineral Resource Estimate was undertaken by MPR Geological Consultants of Perth, Western Australia (“MPR”) as part of the Feasibility Study. MPR estimated mineral resources for the GSS and Wadi Doum deposits using Multiple Indicator Kriging (“MIK”) based on mineralised domains interpreted by MPR and Orca.

Results of the Mineral Resource Estimate are shown below at a range of cut-off grades:

Table 1: Block 14 Mineral Resource Estimate

Relative to the previous Mineral Resource Estimates, this Mineral Resource Estimate is based on an additional 10,792m of drilling in 7 diamond holes and 57 reverse circulation (“RC”) holes completed at GSS and an additional 1,882m of drilling in 3 diamond holes and 8 RC holes completed at Wadi Doum. All intercepts from 2018’s drill program are outlined in Appendix I of this news release.

Results of the Mineral Resource update are shown below by oxidation category at a cut-off grade of 0.6g/t:

Notes: The Mineral Resource has been prepared in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum “CIM Definition Standards for Mineral Resources and Mineral Reserves” (CIM, 2014). Numbers may not add up due to rounding.

“The drilling completed in 2018 has been specifically aimed at developing Mineral Reserves as part of the Feasibility Study. Given the increase in the scope of the Block 14 project, driven by the 2017 discovery of a major fresh water aquifer system and the successful resource drilling campaigns, we expect to see a significant positive change in the scale and scope of the project with the delivery of the Feasibility Study in November. Exploration will now focus on the expansion of high-grade zones identified at Wadi Doum towards further enhancement of the economics and production potential at Block 14 and drill testing of additional high-grade targets previously identified,” commented Richard Clark, CEO and Director of Orca Gold. “Block 14 has exceeded our expectations and continues to demonstrate that it has a lot more to offer. The delivery of our Feasibility Study will establish the initial economics of this project and will form the base for further growth of this exciting gold camp.”

Exploration

Drilling in 2018 has continued to add to the geological understanding of GSS and Wadi Doum culminating in the latest Mineral Resource Estimate. Further upside remains in both deposits as this understanding continues to evolve.

Drilling is ongoing at Block 14 focusing for the remainder of the year on Wadi Doum and satellite targets outside the current Resource. The Company is looking to expand the high-grade zones at Wadi Doum and further test the Liseiwi discovery, where previous drilling intersected 24m grading 3.89g/t, 10m grading 15.32g/t and 8m grading 12g/t.

Feasibility Study

The Mineral Resource Estimate will form the basis of the Feasibility Study, which is on target for completion in November 2018. Below is the status of the Study:

• Capital and operating cost estimates (Complete)
• Geotechnical assessment (Complete)
• Mining contractors have visited site and are preparing bids (In progress)
• Pit optimisation, design and mine scheduling (In progress)
• Fuel and power contracts (In progress)
• Environmental Impact Assessment (Submitted to the Sudan Government for approval)
• +100Mm³ Water Resource discovery (Permitted)
