TORONTO, Oct. 28, 2021 - Arena Minerals Inc. ("Arena" or the "Company") (TSX-V: AN) is pleased to announce that the Board of Sal de la Puna Holdings Ltd. has approved a comprehensive development work program for the Sal de la Puna Project. Sal de la Puna Holdings owns 100% interest in the Sal de la Puna Project ("SDLP") in the Pastos Grandes Basin located in Salta, Argentina, and is jointly owned by Arena (65%) and Ganfeng New Energy Technology Development (Suzhou) Co., Ltd. ("Ganfeng Lithium"; 1772.HK; OTCQX: GNENF) (35%).
The approved work program focuses on expanding the recently announced maiden lithium brine resource estimate (please refer to press release dated October 19, 2021) and advancing processing studies in order to establish an optimal route for the production of high purity lithium products.
Highlights of the approved work program include:
- Drilling to focus on resource upgrade and expansion
- Minimum 3,000 metres of diamond drilling
- 2 large diameter production wells
- Drilling covering 6 claims within Pastos Grandes basin
- Pilot plant and pond construction
- Engineering studies to optimize process routes to produce >30% lithium chloride products
The work program is fully permitted and is set to commence immediately.
"This work program is the backbone of our plan to fast-track the Sal de la Puna Project to a production decision. The drill program will help determine the potential resource on the most prospective claims while establishing a high quality measured and indicated resource on the Almafuerte & Graciela claims. Along with our engineering and processing studies that form part of this program, Arena will be in a great position to compile a preliminary mine plan and corresponding economic study," commented Eduardo Morales, Executive Chairman.
"Thanks to the sizeable backing from our partner Ganfeng Lithium and strategic investor Lithium Americas (TSX: LAC; NYSE: LAC) we are fully funded for the approved work program at SDLP," added William Randall, President & CEO.
Resource Growth Program
The drill program will be focused on the Almafuerte and Graciela blocks which border Millennial Lithium's Pastos Grandes project to the south and south-east. A map showing the proposed locations of the drill holes and wells can be seen in Figure 1. The program has been designed by the Management Committee, Arena and consultants to the Company with the objective of both increasing the category of the current resource and increasing the Project's resource base.
To date, resources have only been defined on the Almafuerte block covering approximately 6.5% of the total landholdings of the Company in the Pastos Grandes basin. Additional drill holes and a production well are planned within the Alamfuerte claim to increase the resource category and conduct long term pump tests to evaluate production potential of the lithium bearing aquifers. If successful, this drilling will allow the Company to graduate portions of the resource to Measured and/or Indicated categories and conduct preliminary wellfield designs, including predicted production capacities.
Priority resource expansion drilling will focus on the Graciela block, located less than one kilometre north of the Almafuerte block. Graciela lies immediately adjacent to established lithium bearing aquifers drilled by other operators in the basin. Favourable geophysics suggest these brine bodies continue onto the Graciela block.
Brine is also interpreted to occur in the Patovica I, Barreal II and southern end of the La Relojera properties, as determined by proximity to known brine bodies and favourable geophysics. TEM lines across these properties indicate the presence of brines at depth, within a well-established lithium bearing basin. Exploration drilling is planned for these properties, more than doubling the drilled area.
Engineering and Metallurgical Program
The main objective of the approved metallurgical program is to optimize Arena's processing technology at SDLP. The process will aim to produce a low volume, concentrated >30% lithium chloride (approximately 6% Li) product that can be transported over great distances cost effectively to produce battery grade lithium carbonate. This process allows a centralized lithium carbonate plant to be constructed off-site at lower altitudes in areas with greater infrastructure and access to skilled labour.
Testing has commenced at laboratory scale and shall proceed to greater and more continuous volumes at a pilot facility to be constructed at SDLP. The pilot facility is fully permitted and will consist of laboratory modules and lined evaporation ponds.
The results will be used to continuously optimize concentration paths culminating in an initial pond design and basic engineering, including inputs for operating cost estimates and capital requirements. These results, along with the resource expansion program, will form the basis of an economic study on SDLP.
Budget
A budget of approximately USD 4 million has been approved and will be contributed on an ownership pro-rata basis by Arena and Ganfeng Lithium. The SDLP work program will be operated by Arena as stipulated in the SDLP Joint Venture Agreement (for more details please refer to press release June 10, 2021).
About Arena Minerals Inc.
Arena owns 65% of the Sal de la Puna Project covering approximately 11,000 hectares of the Pastos Grandes basin located in Salta, Argentina. The claims are highly prospective and share the basin with two advanced lithium brine projects. In addition to Sal de la Puna, the Company owns the Antofalla lithium brine project in Argentina, consisting of four claims covering a total of 6,000 hectares of the central portion of Salar de Antofalla, located immediately south of Albemarle Corporation's Antofalla project. Arena has developed a proprietary brine processing technology using brine type reagents derived from the Antofalla project with the objective of producing more competitive battery grade lithium products.
Arena also owns 80 percent of the Atacama Copper property within the Antofagasta region of Chile, and 5.8 million shares of Astra Exploration. The projects are at low altitudes, within producing mining camps in infrastructure-rich areas, located in the heart of Chile's premier copper mining district.
