Orca Gold Drills 17.4 m at 7.92 g/t Au and Confirms High-Grade Potential at its Block 14 Gold Project in The Republic of The Sudan

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Nov. 21, 2017) - Orca Gold Inc. (TSX VENTURE:ORG) ("Orca" or the "Company") is pleased to announce further results from the ongoing 25,000-metre drilling campaign at its Block 14 Gold Project in The Republic of The Sudan.

HIGHLIGHTS

Drilling Hits High-Grade Shoot Below and Outside Current Resource:

• Drill hole GSDD020A successfully intercepted a high-grade, steeply plunging shoot at depth, returning 17.4m @ 7.92 g/t Au between 354.6m and 372.0m
• The Company will review and evaluate the underground potential at Block 14 if drilling continues to confirm increase of grade at depth

Drilling Confirms Overall Grade Increases at Depth in GSS:

• 30 drill holes, totaling 11,000 metres, have been drilled as part of the Company's current exploration campaign
• Current drilling confirms an overall increase in grade below the GSS current resource, which the Company anticipates will have a positive impact on the resource update and consequently the economic results in the Feasibility Study scheduled for completion in Q2 2018

DETAILS

To date, approximately 11,000 metres (30 holes) of a 25,000-metre programme have been completed. Four diamond core rigs are currently operating at Galat Sufar South ("GSS"), which have been joined by an additional reverse circulation rig in this last week.

The objectives of this programme are to upgrade in-pit resources to Measured and Indicated category and test the potential for resource expansion below the pit shells that formed the basis of the revised preliminary economic assessment of the Block 14 Gold Project (the "Revised PEA") (see News Release dated May 30, 2017).

Results for the first seven core holes from the programme were announced previously (see Company News Release dated October 17, 2017). The table below shows results for the next 10 holes. The balance of the completed holes is in the lab for assaying and will be announced once the results are received.

All holes listed were drilled in the East Zone of the GSS deposit (See Figures 1, 2 & 3 in news release). The results continue to confirm and upgrade mineral resources within the revised PEA pit designs (Infill) and extend mineralization below the previous resource (Outside Resource).

Importantly, the latest drill results confirm an overall increase in grade below the current resource. The Company believes that this will have a positive impact on a new resource calculation and consequently the economic results of the Feasibility Study scheduled for completion in early Q2 2018. Additionally, hole GSDD020A successfully intercepted a high-grade steeply plunging shoot at depth, returning 17.4m @ 7.92 g/t Au between 354.6m and 372.0m. This high-grade intercept, outside and below the current resource, highlights the potential to examine underground options at GSS.

"Drilling at GSS is progressing well with results continuing to demonstrate the potential for the Feasibility Study pits to expand from those contemplated in the Revised PEA. The Company intends to release a new resource update in early 2018, which will form the basis of our Feasibility Study," commented Rick Clark, CEO and Director of Orca. "The intercept in the high-grade shoot is not only impressive in grade but is also significant in width. Ongoing drilling will further test this and other high grade structures at depth towards a review of underground options at both GSS and Wadi Doum. This is an exciting development for Orca and we look forward to reporting on this opportunity as we move into the new year."

Cautionary Statement Regarding Forward-Looking Information

This press release contains forward-looking information and forward-looking statements within the meaning of applicable Canadian securities laws, including statements regarding Orca's (the "Company", the "Corporation", "we" or "our") plans and expectations relating to the Block 14 project ("Block 14") in northern Sudan and the revised Preliminary Economic Assessment (the "Revised PEA") and Feasibility Study ("FS") currently being completed and/or conducted by the Corporation. These statements relate to analyses and other information that are based on forecasts of future results, estimates of amounts not yet determinable and assumptions of management. Statements concerning mineral resource estimates may also be deemed to constitute "forward-looking statements" to the extent that they involve estimates of the mineralization that will be encountered if the property is developed. The assumptions, risk and uncertainties outlined below are non-exhaustive. Should one or more of these risks and uncertainties materialize, or should underlying assumptions prove incorrect, actual results, performance or achievements of the Corporation, or industry results, may vary materially from those described in this press release.
