Meridian Mining UK Finalizes JV with Orosur Mining on Ariquemes Tin Province

Joint Venture formed to create tin-focussed Company in Brazil's second largest tin province.

LONDON, Jan. 13, 2022 - Meridian Mining UK S (TSXV: MNO) (Frankfurt: 2MM) (Tradegate: 2MM) (OTCQB: MRRDF) ("Meridian" or the "Company") today provides an update on its Ariquemes Tin Exploration Portfolio ("Ariquemes"), announcing that it has signed a Joint Venture Agreement (the "Agreement" or the "JV") with Orosur Mining Inc. ("Orosur"). The Agreement provides a mechanism for a staged earn-in by Orosur into the mineral concessions currently held via Meridian Mineração Jaburi S.A., a wholly owned subsidiary of Meridian. Ariquemes comprises an extensive land package in Brazil's second largest tin field. Geophysical and geochemical datasets released by the Companhia De Pesquisa De Recursos Minerais ("CPRM"; Geological service of Brazil) highlights highly prospective signatures consistent with the tin-bearing granites within the Ariquemes area. The Company welcomes the partnership with Orosur, which will allow it to pursue its particular strategic focus on its Cabaçal Cu-Au Project in the state of Mato Grosso while retaining exposure to Ariquemes' long-term potential upside.

Highlights of today's update:

• Meridian signs a Joint Venture of its Ariquemes tin portfolio with Orosur Mining Inc.;
• Orosur shall have the exclusive right for a staged earn-in on the Ariquemes Project;
• • Expenditure of USD 1,000,000 to earn an initial 51% interest over a 24-month period;
  • Expenditure of USD 2,000,000 to earn a 75% interest, after which Meridian can contribute or dilute to a royalty; and
• JV on Ariquemes allows Meridian to focus on its Cabaçal Cu-Au Project in the state of Mato Grosso.

Dr Adrian McArthur, CEO and President of Meridian, comments, "Meridian has communicated for some time its intent to find a suitable partner to advance Ariquemes. Orosur's Board and Management team have extensive experience in South America and concluded a legal due diligence and positive field review at the end of 2021. We are pleased now to announce the signing of the JV Agreement which creates a focussed vehicle to explore the prospective Ariquemes district. The progressive strengthening of the tin price over the past two years has created a resurgence of interest in the belt and optimal conditions for a tin-focussed company to explore for a new generation of discoveries. Both Orosur and Meridian believe the Ariquemes district to be highly prospective. The Agreement allows Meridian to maintain its focus on the Cabaçal VMS copper-gold Belt, its strategic priority, and it wishes Orosur well in pursuing success in Ariquemes for all stakeholders."

Ariquemes

Meridian Mining consolidated a large landholding within the world class Ariquemes Tin District of Rondônia, Brazil's second largest tin field. The area has been evaluated through CPRM's "Áreas de Relevante Interesse Mineral" program - an initiative with Federal backing. The Ariquemes district was selected based on its contribution to Brazil's economy, and the need to reconsider the prospectivity based on available geophysical datasets. Key observations of the datasets and reports released by the CPRM include:

• Cassiterite and Gold were detected in pan-concentrates from a CPRM stream-sediment sampling program (Figure 1). The sampling was conducted at a district scale. The responses are at trace levels, but are considered significant in showing mineralized sources;
• The radiometric responses have identified signatures associated with two mineralized granite series - the Rondônia Suite to the west, and the Santa Clara Suite to the east. The responses extend beyond the mapped granite boundaries, suggesting the granites project under shallow cover;
• The distinctive magnetic signature of tin-bearing granite series extends beyond areas of exposure and projects beneath younger cover sediments within the Ariquemes Project Area. A broad envelop of interest occupied by clusters of favourable magnetic anomalies has been defined;
• Within the Company's license area, the more detailed 1:100,000 maps recently produced as part of the study now show the presence of the prospective granites, along strike to active tin mines, and elsewhere, requiring prospecting follow-up when the licenses are granted.
