President and CEO, Alastair McIntyre, comments, "We are very excited and encouraged with the progress at Santa Beatriz. The geological information and sample results suggest the vein structures are identical to Farellon with the added benefit of higher gold grades and a larger land package containing several vein sets. The location of Santa Beatriz is ideal to supplement our processing capacity at El Peñón with the potential to generate a higher return based on significant gold credits. Our next steps involve moving the project forward at an advanced pace to support a development decision."
Surface and underground mapping and sampling along NE-trending veins was conducted by the technical team as part of the 2024 ongoing exploration program at Santa Beatriz. A total of 5 veins/splays were identified either outcropping on surface, with old mine workings, or with excavator trenching (Figure 2). The total strike of these veins adds up to 1,050 m and range in width from 0.30 to 3.13 m. Inferred projections are not being considered and only actual outcrops were measured and sampled. The main vein, Santa Beatriz, was explored previously with underground workings along a strike length of 275 m.
A total of 98 samples were taken along these veins to complete 37 sampling channels. The channels are perpendicular to the vein and consists of 1 - 4 contiguous samples. In underground workings, the channels include samples taken from the vein and its host-rock (footwall and hanging wall), and were taken systematically every 10 to 15 metres. The best channel sample result belongs to the Santa Beatriz vein and yields 2.45 m with 3.65 %Cu; 0.29 g/t Au; and 26.97 %Fe which includes a 1.08 m sample that yields 8.08 %Cu, 0.63 g/t Au, and 39.49 %Fe. The weighted average grades, true width, and measured strike length of all the veins are summarized in Table 1; and the composite grade of the 37 sampling channels is shown in Table 2.
The Santa Beatriz vein is the best explored to date, strikes N70E, dips steeply to the south, and is hosted by fine grained diorite. The vein consists of massive magnetite that contains discrete bands of chalcopyrite and lesser bornite in patches with halos of coarse grained (up to 3 cm long) crystals of euhedral apatite intergrown with actinolite partially altered to chlorite. These characteristics resemble both the Farellon and Rosario veins, which also share the same structural control. This confirms that these veins belong to the same ore forming hydrothermal system and precipitated under similar physical (depth and temperature) and chemical (ore fluids chemistry) conditions. The other veins mapped on surface to the north from the Santa Beatriz vein footwall (SBFW 01-04), albeit narrower, display similar characteristics suggesting that a larger and deeper hydrothermal system could be feeding these veins.
The positive geological mapping and sample results warrant further exploration and development at Santa Beatriz. The Company is planning to continue with a bulk sample from the underground workings, geophysics, and diamond drilling program to confirm continuity of the vein and grades at depth and along strike. This information will form the basis of a potential mining decision. Existing underground infrastructure at Santa Beatriz can be used to assist in the development and access to the mineralized vein structure at depth.

Altiplano has generated over US$14.9 million from the recovery and sale (after processing costs) of more than 6.55 million pounds of copper with an average grade of 1.8% Cu (2018 Q1-2024 Q1). Cash flow has been re-invested into equipment, underground drilling, expanding underground development at Farellon, enhancing ventilation to increase productivity and capacity, new underground development and exploration, and the start-up of the El Peñón fit-for-purpose mill and flotation plant located 15 km from the Farellon site.

Neither the TSX Venture Exchange nor its Regulation Services Provider (as that term is defined in the policies of the (TSX Venture Exchange) accepts responsibility for the adequacy or accuracy of this release.
This release includes certain statements that may be deemed "forward-looking statements". All statements in this release, other than statements of historical facts, that address exploration drilling, exploitation activities and events or developments that the Company expects are forward-looking statements. A qualified person has not done sufficient work to classify any historical estimates as current mineral resources or mineral reserves and the issuer is not treating the historical estimates as current mineral resources or mineral reserves. The Farellon mine was previously in production dating back to the 1970's with a reported historical production (to a depth of 70 m) yielding approximately 300,000 tonnes at an average grade of 2.5% copper and 0.5g/t gold. This material was processed locally and sold to ENAMI. Altiplano is relying upon past production records, underground sampling and related activities and current diamond drilling to estimate grade and widths of the mineralization to reactivate production. The decision to commence production on the Farellon deposit is not based on a feasibility study of mineral reserves demonstrating economic and technical viability and there is increased uncertainty and economic and technical risks of failure associated with any production decision. Although the Company believes the expectations expressed in such forward-looking statements are based on reasonable assumptions, such statements are not guarantees of future performance and actual results or developments may differ materially from those in the forward-looking statements. Factors that could cause actual results to differ materially from those in forward-looking statements include market prices, exploitation and exploration successes, continuity of mineralization, uncertainties related to the ability to obtain necessary permits, licenses and title and delays due to third party opposition, changes in government policies regarding mining and natural resource exploration and exploitation, and continued availability of capital and financing, and general economic, market or business conditions. Investors are cautioned that any such statements are not guarantees of future performance and actual results or developments may differ materially from those projected in the forward-looking statements.
