Pan American Energy Announces Phase One Drilling Results at the Horizon Lithium Project, Esmeralda County, Nevada

CALGARY, Alberta, May 24, 2023 (GLOBE NEWSWIRE) -- Pan American Energy Corp. (the "Company" or "Pan American") (CSE: PNRG) (OTC PINK: PAANF) (FRA: SS60) is pleased to announce positive drill results from its initial exploratory subsurface drill program, Phase 1, at its Horizon Lithium Project ("Horizon") in Big Smoky Valley, Nevada. The program involved targeted drilling in strategic locations based on extensive geological research conducted by the Company's strategic contractor partner, RESPEC ("RESPEC"). This initial exploratory drilling program consisted of eleven (11) targeted diamond core drill holes on Pan American's 17,334 acres of lithium-bearing claims resulting in the identification of substantial lithium deposits within the region. The successful drill program represents a major milestone for Pan American, showcasing their expertise in identifying and evaluating valuable mineral resources. The Company remains committed to responsible mining practices and intends to continue exploration efforts to further delineate the size, quality, and economic viability of the newly discovered lithium deposits.

Highlights from this Phase 1 drilling program include:

• Peak lithium grade of 2,040 ppm
• 1,118 intervals of lithium-bearing Siebert Fm. sent for assay with 63% returning grades at or above 300 ppm and 44% greater than 600 ppm of lithium
• Total of 7,486.5 ft drilled with outstanding core recovery of Siebert Fm. exceeding 98%
• Setup and implementation of a streamlined core processing facility in Tonopah, NV to provide geotechnical & lithologic logging, core cutting & storage, and sample selection & preparation
• Phase 1 operational success included controlled surface disturbance, minimized environmental impact, and respectable performance by KB Drilling, Inc.
• Drilling was halted on drill hole HL018 at 162 ft and is being evaluated for re-entry

Lithium Concentrations: Lithium concentrations presented in the table incorporate no cut-off reflecting a more robust weighted average of the full dataset per hole. Assay results indicated excellent core recovery and encountered high lithium concentrations with thick zones of mineralization.

Shallow Overburden: The alluvium cover on the property is comparable to industry peers with a similar range of depths. The distribution of fifty-five (55) samples taken from depths shallower than 130 ft, 21 of such samples have ppm values over 300 ppm of lithium.

Depth of Mineralization: Drill holes were advanced as far as 998 ft depth ? doubling the regional peer standard total depth of approximately 500 ft. In doing so, the Company demonstrated that lithium mineralization extends to a more significant range. In addition, lithium bearing claystone at Horizon are extensive and several decimeters thick. The bedrock of the Siebert Formation was not encountered allowing for further exploration at depth.

Deposit Significance: The Pan American team is thrilled by the presence of exceptional lithium concentrations observed in the thorough exploratory drill holes and sample depths. This exciting discovery validates the Company's geological hypotheses and is motivation to expedite further exploration and assessment of these claims, aiming to classify the deposit as an inferred, indicated, and measured resource in accordance with National Instrument 43-101, Standard of Disclosure for Mineral Projects.

Future Plans: Building upon the outcomes of the Phase 1 program, Pan American has begun drilling the Phase 2 comprehensive step-out drill program. This next phase will focus on gaining a better understanding of the deposit. By conducting additional drilling and obtaining more data during Phase 2, the Company will be able to determine the overall grade and thickness of the lithium deposit in the immediate area. These crucial findings will enable Pan American to advance the deposit towards a quantified resource assessment and position Pan American for follow-on exploration programming across the rest of the property.

Jason Latkowcer, Chief Executive Officer, expressed their enthusiasm regarding the recent findings, stating, "Pan American is delighted to announce the results of the Phase 1 drill program that resulted in the discovery of a substantial lithium deposit at the Horizon Lithium Project. This marks a significant step forward in our mission to identify and develop North American critical mineral resources that contribute to the green energy transition. The completion of the 11-hole drill program has provided compelling evidence of another promising lithium resource in the world class jurisdiction of Esmeralda County. We are committed to responsible mining practices and look forward to further exploring and developing this exciting lithium project as we embark on Phase 2 drilling. There is a tremendous amount of property left to explore - we are just getting started!"

As Pan American advances the project, they will collaborate with local communities, regulatory authorities, and stakeholders to ensure the exploration and potential future mining activities are conducted in a sustainable and environmentally conscious manner.

Core Handling and Sampling Procedures:

Core handling and sampling procedures are as follows:

• Cored samples transported twice daily from the drill pad to RESPEC/Pan American Energy core logging headquarters in Tonopah, NV, by RESPEC geologists.
• Detailed core examination of the samples was completed using industry standards for core descriptions by RESPEC geologists. Logging criteria include Geotechnical and Structural parameters (RQD, structure types and infill, planarity, roughness, hardness, and angle to core axis), Lithologic qualifiers (lithofacies, mineralogical composition, and cementation), and acid reactivity for calcium carbonate.
• On-site core-slab sampling program was performed by the RESPEC geologists with a 5% Quality Control insertion rate using Certified Reference Materials (2 pulp types of known Lithium content and 2 separate pulp blanks). Sample selection was completed on every 5-foot depth increments and accounts for notable lithological variations. The program also includes random core-slab sample duplicates from every drill hole in the study area. Once coarse and pulp rejects are returned from ALS Geochemistry, located in Reno, NV, a small percentage will be sent to a check lab.
• Core photography and database management of all sampled intervals and core boxes was performed by RESPEC's field personnel.
• Samples were transported to ALS Geochemistry located in Reno, NV, by RESPEC field personnel.
• Chain of custody and sample assaying tracking/controls were kept throughout the entire program. ALS Geochemistry is independent of the Company.
• ALS Geochemistry performed ME-MS61 multi-element analyses by four acid digestion and ICP-MS on all of our Lithium-Bearing claystone samples.
