VANCOUVER, British Columbia, November 19, 2021 (GLOBE NEWSWIRE) – Alpha Lithium Corporation (TSX.V: ALLI) (OTC: APHLF) (Frankfurt: 2P62) (“Alpha“or the”Society“) is very pleased to announce the drilling results of its original six-well program. The drill program was a critical component of Alpha’s initial exploration campaign in the 100% owned Tolillar Salar, over 27,500 hectares, located in the province of Salta, Argentina.
The objectives of the initial campaign were to (i) improve our understanding of the conceptual hydrogeological model of the salar and (ii) determine the lithium contents and the hydraulic parameters of the brine aquifer. Both objectives were successfully achieved and gave confidence to continue a second exploration campaign.
To date, Alpha has drilled a total of six exploration holes at varying depths. The first well was very shallow and drilled primarily to confirm and provide a baseline for the original Vertical Electric Borehole (“VES”) geophysical survey completed in 2020. The remaining five production holes were drilled to depths of between 78 and 352 meters. Each well was cased with 6 “or 8” production casing and then flow tested to assess well efficiency, sustainable pumping capacity and aquifer parameters. Brine samples were collected during testing of each well and sent for analysis to the SGS laboratory in the regional capital of Salta. As the drilling campaign progressed, the technical team recalibrated the VES surveys with the newly obtained information and continually refined the targets and subsequent depths.
Drill results have shown continuous improvement and the most recently tested drill wells have encountered constant lithium levels between 345 and 351 mg / L.
The first three exploration wells encountered lithium contents ranging from 194 to 218 mg / L during pumping tests with flow rates between 55 and 100 m3/time. The flow rate on the final hole, with 351 mg / L lithium concentration, reached 130 m3/time. A higher pumping rate was achievable but was limited by the maximum achievable capacity of the pumping equipment.
In addition to the high flow rates and lithium concentrations, the Tolillar Salar also produced brine with very low levels of impurities. For example, the range for magnesium / lithium (“Mg: Li”) ratios was between 4.90 and 5.37, with an average for the five wells at 5.0, a top quartile result for the salars in Argentina. .
Brad Nichol, President and CEO, said: “We are obviously very pleased to present the fantastic results of our first chapter of drilling in the Tolillar Salar. The original wellbore drilled by previous owners in 2018 yielded 204 mg / L of lithium from samples taken at 190 meters and a calculated transmissibility of 60 m3/time. This drilling program produced an improvement of more than 70% in lithium concentration and an improvement of more than 300% in the transmissibility of the reservoir. Nichol added, “Additionally, our technical team studied and fine-tuned in real time and continually improved results, leaving us with tremendous confidence to undertake a second larger campaign focused on delivering a resource.

Based on the early successes, the Company has already started drilling two additional production wells and two freshwater wells on the Tolillar Salar. Two of these wells have been drilled and are awaiting testing and a third well is currently being drilled.
Now armed with continuously improved geological and hydrogeological models, the Company plans and authorizes the drilling of at least ten additional production wells and expands the geophysical survey to include 70 additional VES drill points (more than double the original VES survey).
The objective of the second campaign is to define and expand the lithium resource using a combination of VES boreholes, coring, production wells and pressure monitoring boreholes.

About Alpha Lithium (TSX.V: ALLI) (OTC: APHLF) (Frankfurt: 2P62)
Alpha Lithium is a team of industry professionals and experienced stakeholders focused on the development of Salars Tolillar and Hombre Muerto. In Tolillar, we have gathered 100% ownership of what may be one of Argentina’s last undeveloped lithium salars, spanning 27,500 hectares (67,954 acres), neighboring multibillion-dollar lithium players. dollars in the heart of the famous “Lithium Triangle”. At Hombre Muerto, we continue to expand our presence to over 5,000 hectares (12,570 acres) in one of the highest quality and longest producing lithium salars in the world. Other companies in the region exploring for lithium brines or currently in production include Orocobre Limited, Galaxy Lithium, Livent Corporation and POSCO in Salar del Hombre Muerto; Orocobre in Salar Olaroz; Eramine SudAmerica SA at Salar de Centenario; and Gangfeng and Lithium Americas in the Salar de Cauchari.
