Anaconda Mining Intersects 2.73 g/t Gold over 6.5 metres and 4.57 g/t Gold over 3.0 metres and Identifies New Shallow Mineralization at Goldboro
The Infill Drill Program successfully intersected several new zones of near-surface gold mineralization on the northern side of the Goldboro Deposit between the two proposed open pits, over a strike length of 200 metres, as well as infilled deeper sections of the Goldboro Deposit (Exhibits A, B, C). The new near-surface mineralized zones were not included within the Mineral Resource Estimate announced on December 16, 2021, and present near-term potential to upgrade both near surface and underground Inferred Mineral Resources, further optimize the pit design outlined in the Feasibility Study, reduce the strip ratio, and positively impact the value of the Project. Successful intersection and infill drilling of deeper, underground Inferred Mineral Resource further highlights the potential for an underground mining phase for the Project. Only 5 of the 19 drill holes completed in this program were included in the recent Mineral Resource Estimate update with the remainder to contribute to future updates.
Selected composited highlights (core length) from the drill program include:
- 26.10 grams per tonne ("g/t") over 0.5 metres within a broader zone consisting of 2.73 g/t gold over 6.5 metres (94.5 to 101.0 metres) in diamond drill hole BR-21-300;
- 17.20 g/t gold over 0.5 metres within a broader zone consisting of 3.91 g/t gold over 2.5 metres (137.5 to 140.0 metres) in diamond drill hole BR-21-301;
- 20.60 g/t gold over 0.5 metres within a broader zone consisting of 4.57 g/t gold over 3.0 metres (148.1 to 151.1 metres) in diamond drill hole BR-21-305;
- 13.30 g/t gold over 0.6 metres within a broader zone consisting of 1.49 g/t gold over 7.0 metres (157.5 to 164.5 metres) in diamond drill hole BR-21-305;
- 11.00 g/t gold over 0.5 metres (94.7 to 95.2 metres) in diamond drill hole BR-21-306;
- 31.30 g/t gold over 0.5 metres (126.2 to 126.7 metres) in diamond drill hole BR-21-307;
- 10.40 g/t gold over 1.0 metre (38.0 to 39.0 metres) in diamond drill hole BR-21-308;
- 34.80 g/t gold over 0.5 metres (145.7 to 146.2 metres) in diamond drill hole BR-21-308; and
- 24.50 g/t gold over 0.6 metres (235.6 to 236.2 metres) in diamond drill hole BR-21-308.
"This infill drill program and the related results highlight the tremendous potential that continues to exist for the Goldboro Gold Project. Since acquiring the Project in 2017, we have grown the deposit significantly, culminating in the recent Mineral Resource Estimate update which demonstrates a combined open pit and underground Measured and Indicated Mineral Resource of 2,581,000 ounces and a combined open pit and underground Inferred Mineral Resource of 484,000 ounces. In the fall 2021 we recognized an opportunity to target and potentially upgrade inferred near-surface and underground mineral resources in the area between the two open pits outlined in the Goldboro Feasibility Study. Several new zones of near surface mineralization were encountered within and between the two open pits over a strike length of 200 metres, demonstrating the potential to upgrade near-surface Inferred Resources and reduce the strip ratio. The assay results from the drill program also show continuity of high-grade gold within broader mineralized envelopes within the underground resource, indicating the potential to further upgrade underground Mineral Resources. Looking ahead to the new year, we are excited to commence further drill programs to both upgrade and expand the Goldboro Mineral Resource, which has the near-term potential to further increase value to what is already a robust, economically valuable Project."

Mineral Resource Estimate Notes
- 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.
- Mineral Resources are inclusive of Mineral Reserves.
- Open Pit Mineral Resources are reported at a cut-off grade of 0.45 g/t gold that is based on a gold price of C$2,000/oz (~US$1,600/oz) and a metallurgical recovery factor of 89% around cut-off as calculated from ((GRADE-(0.0262*LN(GRADE)+0.0712))/GRADE*100)-0.083.
- 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$1,600/oz) and a gold processing recovery factor of 97%.
- Assays were variably capped on a wireframe-by-wireframe basis.
- Specific gravity was applied using weighted averages to each individual wireframe.
- Effective date of the Mineral Resource Estimate is November 15, 2021.
- All figures are rounded to reflect the relative accuracy of the estimates and totals may not add correctly.
- Excludes unclassified mineralization located within mined out areas.
- Reported from within a mineralization envelope accounting for mineral continuity.

Qualified Person and Technical Report Notes
A Technical Report prepared in accordance with NI 43-101 for the Goldboro Gold Project Feasibility Study will be filed on SEDAR (www.sedar.com) before the end of January 2022. Readers are encouraged to read the Technical Report in its entirety, including all qualifications, assumptions and exclusions that relate to the Mineral Resource and Mineral Reserve and Feasibility Study. The Technical Report is intended to be read as a whole, and sections should not be read or relied upon out of context.
^ Composited assays shown in Exhibit A and B from the October 12, 2021 press release may vary from those presented in the original press release due to the inclusion of assays obtained using total pulp metallic analysis (see below) obtained since October 12, 2021.
All samples and the resultant composites referred to in this release are collected using QA/QC protocols including the regular insertion of standards and blanks within the sample batch for analysis and check assays of select samples. All samples quoted in this release were analyzed at Eastern Analytical Ltd. in Springdale, NL, for Au by fire assay (30 g) with an AA finish.
All assays in this press release are reported as fire assays only. For samples analyzing greater than 0.5 g/t Au via 30 g fire assay, these samples will be re-analyzed at Eastern Analytical Ltd. via total pulp metallics. For the total pulp metallics analysis, the entire sample is crushed to -10mesh and pulverized to 95% -150mesh. The total sample is then weighed and screened to 150mesh. The +150mesh fraction is fire assayed for Au, and a 30 g subsample of the -150mesh fraction analyzed via fire assay. A weighted average gold grade is calculated for the final reportable gold grade. Total pulp metallics assays for drillholes sited within this press release may be updated in a future news release.
The Drill Program is funded using existing flow through funds but has also benefited from a grant received from the Government of Nova Scotia through a Mineral Resources Development Fund, shared funding exploration grant MRDF-2021-SF-11.
Kevin Bullock, P.Eng., President and Chief Executive Officer of Anaconda, and Paul McNeill, P. Geo., VP Exploration of Anaconda, are "Qualified Person(s)" as such term is defined under NI 43-101 Standards for Disclosure for Mineral Projects and have each reviewed and approved the scientific and technical information and data included in this press release.
