Highlights of the Goldboro Gold Project PEA

• After-tax Net Present Value at a 5% discount rate ("NPV 5%") of $547 million and an after-tax Internal Rate of Return ("IRR") of 24.4%, with an after-tax payback of 3.2 years based on a gold price of $2,000 per ounce (US$1,550 at an exchange rate of 1.29 C$:US$);
• Pre-tax NPV 5% of $805 million and a pre-tax IRR of 29.0%, with a pre-tax payback period of 2.9 years;
• Total gold recovered of over 1,950,000 ounces over a 17.6-year life of mine, based on 15.0 Mt at 2.09 grams per tonne ("g/t") gold from surface mining, 6.0 Mt at 4.89 g/t gold from underground mining, and 3.2 Mt at 0.63 g/t gold from a low-grade stockpile;

• Initial capital cost ("Capex") of $286 million resulting in an after-tax NPV 5% to Capex ratio of 1.9;
• Average gold production of over 89,500 ounces per year over the first 7 years of production from surface mining, increasing to average annual production of over 120,000 ounces in years 8 through 18;
• Life-of-Mine Operating Cash Costs¹ of $862 (US$668) per ounce sold and All-In Sustaining Costs¹ ("AISC") of $1,031 (US$799) per ounce sold;
• Mill capacity of 4,000 tonnes per day ("tpd") based on combined gravity and leaching circuit, demonstrating an average gold recovery of 96.4%; and
• At a gold price of $2,200 (US$1,705), Goldboro could generate cumulative after-tax net cash flows of approximately $1.4 billion, an after-tax NPV 5% of over $700 million and an after-tax IRR of 29.2%.

* Cautionary statement NI 43-101: The PEA was prepared in accordance with NI 43-101. Readers are cautioned that the PEA is preliminary in nature. It includes inferred Mineral Resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the PEA will be realized. Mineral Resources that are not mineral reserves do not have demonstrated economic viability.

The Goldboro Gold Project Preliminary Economic Assessment

The PEA was completed by Nordmin Engineering Ltd. ("Nordmin") as Lead, Mining, and Geological Consultant. Knight Piésold Ltd. ("Knight Piésold") acted as Tailings Consultant, GHD Ltd. ("GHD") as Site Water Management and Environmental Consultant, Ausenco Engineering Canada Inc. ("Ausenco") as Metallurgical and Processing Consultant, Lorax Environmental Services Limited ("Lorax") as Geochemistry Consultant, and McCallum Environmental Ltd. ("McCallum") as Consultation and Permitting Consultant. The Goldboro Gold Project Mineral Resource Estimate, effective February 7, 2021, was prepared by Nordmin.

Goldboro Gold Project - Mineral Resource Estimate

The Mineral Resource, as announced on February 22, 2021 and presented in Table 2, was prepared by Independent Qualified Person Glen Kuntz, P. Geo. of Nordmin. The Mineral Resource is based on validated results of 635 surface and underground drill holes, for a total of 113,132.9 metres of diamond drilling, including 45,408.7 metres conducted by Anaconda, that was completed between 1984 and the effective date of February 7, 2021. Please refer to the Technical Report for further details.

Table 2: Mineral Resource Statement for the Goldboro Gold Project

^ Combined Open Pit and Underground Mineral Resources; The Open Pit Mineral Resource is based on a 0.44 g/t gold cut-off grade, and the Underground Mineral Resource is based on 2.60 g/t gold cut-off grade.

Mineral Resource Estimate Notes

1. Mineral Resources were prepared in accordance with NI 43-101 and the CIM Definition Standards for Mineral Resources and Mineral Reserves (2014) and the CIM Estimation of Mineral Resources and Mineral Reserves Best Practice Guidelines (2019). Mineral Resources that are not mineral reserves do not have demonstrated economic viability. This estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, sociopolitical, marketing, or other relevant issues.
2. Open Pit Mineral Resources are reported at a cut-off grade of 0.44 g/t gold that is based on a gold price of C$2,000/oz (~US$1,550/oz) and a gold processing recovery factor of 96%.
3. Underground Mineral Resource is reported at a cut-off grade of 2.60 g/t gold that is based on a gold price of C$2,000/oz (~US$1,550/oz) and a gold processing recovery factor of 97%.
4. Assays were variably capped on a wireframe-by-wireframe basis.
5. Specific gravity was applied using weighted averages to each individual wireframe.
6. Mineral Resource effective date February 7, 2021.
7. All figures are rounded to reflect the relative accuracy of the estimates and totals may not add correctly.
8. Excludes unclassified mineralization located within mined out areas.
9. Reported from within a mineralization envelope accounting for mineral continuity.

Disclosure of a scientific or technical nature in this news release has been approved by Paul McNeill, P. Geo., VP Exploration with Anaconda Mining Inc., a "Qualified Person".

ABOUT ANACONDA

Anaconda Mining is a TSX and OTCQX-listed gold mining, development, and exploration company, focused in the top-tier Canadian mining jurisdictions of Newfoundland and Nova Scotia. The Company is advancing the Goldboro Gold Project in Nova Scotia, a significant growth project with Measured and Indicated Mineral Resources of 1.9 million ounces (16.0 million tonnes at 3.78 g/t gold) and Inferred Mineral Resources of 0.8 million ounces (5.3 million tonnes at 4.68 g/t gold) (Please see the Technical Report for further details). Anaconda also operates mining and milling operations in the prolific Baie Verte Mining District of Newfoundland which includes the fully permitted Pine Cove Mill, tailings facility and deep-water port, as well as ~15,000 hectares of highly prospective mineral property, including those adjacent to the past producing, high-grade Nugget Pond Mine at its Tilt Cove Gold Project.

NON-IFRS MEASURES

Anaconda has included certain non-IFRS performance measures as detailed below. In the gold mining industry, these are common performance measures but may not be comparable to similar measures presented by other issuers. The Company believes that, in addition to conventional measures prepared in accordance with IFRS, certain investors use this information to evaluate the Company's performance and ability to generate cash flow. Accordingly, it is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS.

Operating Cash Costs per Ounce of Gold - Anaconda calculates operating cash costs per ounce by dividing operating expenses per the consolidated statement of operations, net of silver sales by-product revenue, by the gold ounces sold during the applicable period. Operating expenses include mine site operating costs such as mining, processing and administration as well as royalties, however, excludes depletion and depreciation and rehabilitation costs.

All-In Sustaining Costs per Ounce of Gold - Anaconda has adopted an all-in sustaining cost ("AISC") performance measure that reflects all of the expenditures that are required to produce an ounce of gold from current operations. The Company defines all-in sustaining costs as the sum of operating cash costs (per above), sustaining capital (capital required to maintain current operations at existing levels), sustaining exploration, and rehabilitation and reclamation costs. All-in sustaining costs excludes initial capital expenditures, financing costs, corporate general and administrative costs and salvage value, and taxes. AISC per Ounce is calculated as AISC divided by payable gold ounces.
