Cautionary Statements Regarding Forward-Looking Information and Non-IFRS Financial Measures Certain information contained or incorporated by reference in this presentation of Harte Gold Corp. (“Hart Gold” or the “Company”), including any information relating to the Company’s strategy, the Sugar Zone Mine Property, plans or future financial or operating performance, constitutes “forward-looking statements”, within the meaning of applicable securities legislation. All statements, other than statements of historical fact, are forward-looking statements. The words "seek", "anticipate", "budget", "plan", "continue", “envisage”, "estimate", "expect", "forecast", "may", "will", "project", "predict", "potential", "targeting", "intend", "could", "might", "should", "believe" and similar words suggesting future outcomes or statements regarding an outlook identify forward-looking statements. In particular, this presentation contains forward-looking statements including, without limitation, with respect to: announcing Feasibility Study results in early Q1 2021; 2021E gold production of 60,000 to 65,000 ounces; achieving 800 tpd mine production in Q1 2021; increasing development rates to over 13 metres per day by Q1 2021; increasing the number of active mining areas to six by Q1 2021; estimates of total cash costs per ounce, AISC per ounce, projected capital, operating and exploration expenditures; mine life and production rates; estimated timing for continued development of and production from, the Sugar Zone Mine Property; anticipated gold production from the Sugar Zone Mine Property; the relationship between the Company and BNP Paribas and Appian; and further exploration activities.

Forward-looking statements are necessarily based upon a number of estimates and assumptions including material estimates and assumptions related to the factors set forth below that, while considered reasonable by the Company as at the date of this presentation in light of management’s experience and perception of current conditions and expected developments, are inherently subject to significant business, economic and competitive uncertainties and contingencies. Known and unknown factors could cause actual results to differ materially from those projected in the forward-looking statements and undue reliance should not be placed on such statements and information. Such factors include, but are not limited to: fluctuations in the spot and forward price of gold; the speculative nature of mineral exploration and development; changes in mineral production performance; exploitation and exploration successes; Company’s ability to attract and retain qualified candidates to join the Company’s management team and board of directors; diminishing quantities or grades of reserves and resources; increased costs, delays, suspensions and technical challenges associated with the development and construction of capital projects; operating or technical difficulties in connection with mining or development activities, including geotechnical challenges and disruptions in the maintenance or provision of required infrastructure and information technology systems; failure to comply with environmental and health and safety laws and regulations; timing of receipt of, or failure to comply with, necessary permits and approvals; uncertainty whether the Sugar Zone Mine Property targeted investments will meet the Company’s capital allocation objectives and internal hurdle rate; the impact of global liquidity and credit availability on the timing of cash flows and the values of assets and liabilities based on projected future cash flows; the impact of inflation; fluctuations in the currency markets; damage to the Company’s reputation due to the actual or perceived occurrence of any number of events, including negative publicity with respect to the Company’s handling of environmental matters or dealings with community groups, whether true or not the possibility that future exploration results will not be consistent with the Company’s expectations; risks that exploration data may be incomplete and considerable additional work may be required to complete further evaluation, including but not limited to drilling, engineering and socioeconomic studies and investment; risk of loss due to acts of war, terrorism, sabotage and civil disturbances; litigation and legal and administrative proceedings; business opportunities that may be presented to, or pursued by, the Company; risks associated with employee relations including loss of key employees; increased costs and physical risks, including extreme weather events and resource shortages, related to climate change; and availability and increased costs associated with mining inputs and labor. In addition, there are risks and hazards associated with the business of mineral exploration, development and mining, including environmental hazards, industrial accidents, unusual or unexpected formations, pressures, cave-ins, flooding and gold concentrate losses (and the risk of inadequate insurance, or inability to obtain insurance, to cover these risks). Many of these uncertainties and contingencies can affect our actual results and could cause actual results to differ materially from those expressed or implied in any forward-looking statements made by, or on behalf of, us. Readers are cautioned that forward-looking statements are not guarantees of future performance. All of the forward-looking statements made in this presentation are qualified by these cautionary statements. Specific reference is made to the most recent Annual Information Form and in other filings of the Company with securities and regulatory authorities which are available on SEDAR at www.sedar.com for a more detailed discussion of some of the factors and risks underlying forward-looking statements that may affect the Company’s ability to achieve the expectations set forth in the forward-looking statements contained in this presentation. The Company 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 by applicable law In this presentation we use the terms “EBITDA”, “cash operating cost” and “All-In Sustaining Cost” or “AISC”. These should be considered non-IFRS financial measures as defined in applicable Canadian securities laws and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS.

Opportunities to Further Enhance Value •

Expansion of near-mine mineralization along strike •

•

Expansion of mineralization at depth

• •

Step-out and infill drilling along strike at Sugar Zone South, Middle Zone and Wolf Zone to add additional sources of ore feed, increasing overall ounces per vertical metre

Infill drilling of Inferred Resources at depth to extend mine life

Cost optimization, particularly related to paste backfill vs. rockfill •

Complete a trade-off study analysis of continuing solely with rockfill as a primary backfill method, instead of paste backfill, with the potential of further reducing operating and capital costs

For readers to fully understand the information in this presentation, they should read the technical reports identified below in their entirety, including all qualifications, assumptions and exclusions that relate to the information set out in this presentation which qualifies the Technical Information. Readers are advised that Mineral Resource estimates that are not Mineral Reserves do not have demonstrated economic viability. The Disclosure Documents are each intended to be read as a whole, and sections should not be read or relied upon out of context. The Technical Information is subject to the assumptions and qualifications contained in the Disclosure Documents.

The Mineral Reserve estimate was prepared under the supervision of Mr. Chris McCann (P.Eng), Director of Technical Services for the Company. Mr. McCann is a Qualified Person as defined by NI 43-101. The Mineral Resource estimate was prepared by Mr. Vincent Cardin-Tremblay (P.Geo), former VP Geological Services for the Company. Mr. Cardin-Tremblay is a Qualified Person as defined by NI 43-101.

The Mineral Reserve estimate in this presentation is current to December 31, 2020. The Mineral Reserve estimate was prepared using the resource model under the Mineral Resource estimate.

Notes to Mineral Resource and Mineral Reserve Estimates The Mineral Resource estimate in this presentation is dated September 30, 2020 and the Mineral Resource ounces are inclusive of the Mineral Reserve ounces.

The stated Mineral Resources comply with the requirements of National Instrument 43-101 – Standards of Disclosure for Mineral Projects ("NI 43-101") and are classified in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum's "CIM Definition Standards – For Mineral Resources and Mineral Reserves" (the “CIM Definition Standards”).

Mineral Resources, which are not Mineral Reserves, do not have demonstrated economic viability.

The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues.

The Inferred Mineral Resource in this estimate has a lower level of confidence than that applied to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of the Inferred Mineral Resource could be upgraded to an Indicated Mineral Resource with continued exploration.

The Mineral Resource estimate was prepared by Mr. Vincent Cardin-Tremblay (P.Geo), former VP Geological Services for the Company. Mr. Cardin-Tremblay is a QP as defined by NI 43-101.

Mineral Resources have been estimated as of September 30, 2020 using a gold price assumption of US$1,600 per ounce Au. A resource cut-off grade of 3.0 g/t Au has been estimated based on operating cost projections and applicable metallurgical recovery. The cut-off grade was used in combination with a minimum mining width factor of 1.8m to define the resource.

Numbers may not add due to rounding.

The Mineral Reserve estimate presented in the following table is current to December 31, 2020.

The stated Mineral Reserves comply with the requirements of NI 43-101 and are classified in accordance with the CIM Definition Standards. Mineral Reserve estimates reflect the Company's reasonable expectation that all necessary permits and approvals will be obtained and maintained.

Mineral Reserves are the economic portion of the Indicated Mineral Resources. Mineral Reserve estimates include mining dilution at grades assumed to be zero.

The 2020 Mineral Reserve estimate was prepared under the supervision of Mr. Chris McCann (P.Eng), Director of Technical Services for the Company. Mr. McCann is a QP as defined by NI 43-101.

The Mineral Reserves were estimated as of December 31, 2020 using a gold price assumption of US$1,450 per ounce Au. A mining cut-off grade of 5.0 g/t Au has been estimated based on operating cost projections, sustaining capital development cost, mining dilution and recovery, royalty payment requirements and applicable metallurgical recovery.

Numbers may not add due to rounding.
