VANCOUVER, Sept. 14, 2020 - Orca Gold Inc.

"The Revised Feasibility Study clearly demonstrates the improved economics and scope of the proposed development and operation at Block 14 following the early works engineering and selection of LNG to fuel the power station. At a production rate of almost 230,000 ounces of gold per annum for the first seven years, a low production cash cost per ounce and a significant exploration upside, this project stands out on an international scale," commented Richard P. Clark, Chief Executive Officer of Orca. "With positive political change in Sudan progressing, the Company is confident of securing development financing in the coming months; discussions are ongoing."

Mining and Processing:
The preferred mining option for Block 14 is a conventional truck and shovel open pit operation feeding a mineral processing circuit incorporating primary crushing, SAG and Ball mill grinding followed by carbon-in-pulp leaching, stripping and electrowinning.
Pre-production will enable the training of the mining crews and is estimated to produce 0.90Mt of waste stripping and 0.35Mt of ore, which will be stockpiled. The mining will be completed in eight years at an average mining rate of 22Mtpa. A low-grade stockpile (average 0.71g/t) will be created which enables processing of higher grade ore for the first 7 years of the mine life with an average grade of 1.49g/t. The stockpiled ore will be treated over the last 6.6 years.
77.3MT @ 1.07g/t will be mined from the GSS group of pits adjacent the processing plant. 2.6Mt @ 2.36g/t will be mined from the Wadi Doum satellite deposit and trucked 65km to the processing plant during the first five years of the mine life.
Operating costs are based on assumed fuel prices of $0.60/l ($0.70/l - Nov '18) for diesel and LNG price $9.70/MMTU delivered to site ($0.525/l for HFO380 - Nov '18). LOM power costs used equate to $0.1083/kWhr ($0.136/kWhr – Nov '18).

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 Feasibility Study ("RFS"). 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 presentation.
Any statements that express or involve discussions with respect to predictions, expectations, beliefs, plans, projections, objectives, assumptions or future events or performance (often, but not always, identified by words or phrases such as "expects", "anticipates", "believes", "plans", "projects", "estimates", "assumes", "intends", "strategy", "goals", "objectives", "potential", "possible" or variations thereof or stating that certain actions, events, conditions or results "may", "could", "would", "should", "might" or "will" be taken, occur or be achieved, or the negative of any of these terms and similar expressions) are not statements of historical fact and may be forward-looking statements.
Forward-looking statements and forward-looking information are not guarantees of future performance and are based upon a number of estimates and assumptions of management at the date the statements are made including without limitation, assumptions about the following (the "Forward-Looking Factors"): future prices of gold and other metals; successful exploration, development, and production of Block 14; the timing and completion of the RFS; performance of contractual obligations by counterparties; operating conditions; political stability; obtaining governmental approvals and financing on time; financial projections and budgets; obtaining licenses and permits; government regulation of the Corporation's mining activities; environmental risks and expenses; market conditions; the securities market; price volatility of the Corporation's securities; currency exchange rates; foreign mining tax regimes; insurance and uninsured risks; financial projections and results; competition; availability of sufficient capital, infrastructure, equipment and labour; dependence on key personnel; dependence on outside parties; conflicts of interest; litigation; land title issues; local community issues; estimation of mineral resources; realization of mineral resources; timing and amount of estimated future production; the life of Block 14; reclamation obligations; changes in project parameters as plans continue to be evaluated; and anticipated costs and expenditures and our ability to achieve the Corporation's goals. While we consider these assumptions to be reasonable, the assumptions are inherently subject to significant business, social, economic, political, regulatory, competitive and other risks and uncertainties, contingencies, many of which are based on factors and events that are not within the control of the Corporation and there is no assurance they will prove to be correct.
Forward-looking statements are subject to a variety of known and unknown risks, uncertainties and other factors that could cause actual events or results to differ from those reflected in the forward-looking statements, including, without limitation known and unknown risks, uncertainties and other factors relating to the Forward-Looking Factors above, and those factors disclosed under the heading "Risk Factors" in the Corporation's documents filed from time to time with the securities regulators in the provinces of Canada.
In addition, a number of other factors could cause the actual results, performance or achievements of the Corporation to differ materially from any future results, performance or achievements expressed or implied by the forward-looking information, and there is no assurance that the actual results, performance or achievements of the Corporation will be consistent with them. For further details, reference is made to the risk factors discussed or referred to in the Corporation's annual and interim management's discussion and analyses on file with the Canadian securities regulatory authorities and available electronically on the SEDAR website at www.sedar.com. Although the Corporation has attempted to identify important factors that could cause actual actions, events, results, performance or achievements to differ materially from those described in forward-looking statements and forward-looking information, there may be other factors that cause actions, events, results, performance or achievements not to be as anticipated, estimated or intended. There can be no assurance that forward-looking statements or information will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Such forward-looking statements and information are made or given as at the date of this presentation and the Corporation disclaims any intention or obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as required under applicable securities law.
