Aris Gold Announces Plans to Start Marmato Lower Mine Construction and Reports Increased Mineral Resource Estimate

VANCOUVER, Nov. 11, 2021 - Aris Gold Corp. (Aris Gold or the Company) (TSX: ARIS) (OTCQX: ALLXF) announces its project team has completed several Lower Mine optimizations with Wood PLC, the Company's EPCM contractor. Construction of the new camp and administrative areas is scheduled to begin in late November 2021 followed by the new portal and decline to begin in December 2021. The Lower Mine project includes a new decline and a 4,000 tonne per day (tpd) processing facility to expand on the existing Upper Mine operations. First gold production from the Lower Mine is expected in Q4 2023. In addition, an updated mineral resource estimate has been completed with an effective date of June 30, 2021, representing a 42% increase in Measured and Indicated mineral resources to 5.8 million ounces (Moz) of gold, comprised of 56.9 million tonnes at 3.2 grams per tonne (g/t) gold, compared to the previous estimate effective March 17, 2020. This growth in Measured and Indicated mineral resources includes an 81% increase of contained gold ounces in the Lower Mine.

Marmato Exploration Drill Program and Mineral Resource Estimate

• A 35,000-metre drill program began in May 2020, following completion of the Marmato Expansion Pre-Feasibility Study (PFS) led by SRK Consulting. The drill program had two objectives: (1) convert Inferred mineral resources to the Indicated category; and (2) test potential areas at depth and along strike.
• Between May 2020 and June 30, 2021, results were received for 43 holes totalling 27,737 metres, or approximately 80% of the total program.
• The new holes infilled existing drilling in the lower eastern half of the Marmato Lower Mine, converting Inferred mineral resources to Indicated, and expanded the mineral resource at depth and towards the east. The drill results demonstrate continuity of grades and widths and confirm the quality and interpretation of the mineralized zones, currently extending 800 metres vertically from 1,000 metres to 200 metres elevation, and along strike for over 950 metres.
• The drill program is ongoing and since June 30, 2021, eight more holes (4,543 metres) have been drilled and a further six holes are in progress.
• The Marmato deposit is still open with high-grade mineralization along strike and at depth with opportunities for further growth. Additional drill programs are in the planning stage.
• With an effective date of June 30, 2021, the updated mineral resource estimate (MRE) is as follows:
• • Measured and Indicated mineral resources of 5.8 Moz gold comprised of 56.9 million tonnes at 3.2 g/t gold, representing a 42% increase in contained gold ounces from the PFS MRE; and
  • Inferred mineral resources of 2.6 Moz gold comprised of 30.8 million tonnes at 2.6 g/t gold, representing an 18% increase in contained gold ounces from the PFS MRE.
  • Additional details for the MRE are included in Table 1 below and comparisons to the PFS MRE (effective March 17, 2020) are included in Figure 1.

Aris Gold CEO Neil Woodyer stated "Following our selection of Wood as our EPCM contractor in April 2021, we have completed several optimizations for the Lower Mine and are now ready to begin purchasing long-lead order items. Our Lower Mine capital cost estimate remains in line with the PFS estimate of US$270 million after factoring in our decision to use a mining contractor rather than purchase an owner-mining fleet. By using a mining contractor, we expect to speed up the development of the Lower Mine ramp and increase overall efficiencies. First gold production from the Lower Mine is expected in Q4 2023. We maintain regular contact with the Caldas Department authorities regarding completion of the amendments to our environmental permits and with our existing financial resources, we are ready to commence the Lower Mine construction.

"We have also maintained a high level of exploration activity, which, as at the end of June, has resulted in large increases to the mineral resource estimates at the Marmato Lower Mine. Our exploration program has demonstrated meaningful upside potential at Marmato, and we are now planning our next drill program."

Highlights of the 2020 PFS for the Marmato Expansion Project and Next Steps

• The life of mine plan for the PFS was based on a mineral reserve of 2.0 Moz of gold consisting of 19.7 million tonnes at an average grade of 3.2 g/t gold.
• The PFS gold production profile averages approximately 165,000 oz per year from 2024 through 2033 once the Lower Mine is in full production.
• We have commenced the work to prepare a new mineral reserve estimate based on the Updated MRE and a refreshed PFS technical report. On the basis of the increases to the Updated MRE, the updated gold production profile is expected to extend by several years beyond 2033.

Qualified Persons and Technical Information

Measured and Indicated mineral resources are inclusive of mineral reserves. Mineral resources and reserves are as defined by the Canadian Institute of Mining, Metallurgy, and Petroleum's 2014 Definition Standards for Mineral Resources & Mineral Reserves. Mineral resources are not mineral reserves and have no demonstrated economic viability. There are no known legal, political, environmental, or other risks that could materially affect the potential development of the mineral resources.
