Altiplano Discovers New Zone at Maria Luisa;

Drills 10.50 Metres of 3.76 g/t Gold and 3.83%

Copper

Edmonton, Alberta--(Newsfile Corp. - August 9, 2022) -

Altiplano Metals Inc

. (TSXV: APN) (WKN:

A2JNFG) ("

Altiplano

" or the "

Company

") is pleased to announce a new discovery at the Maria Luisa

Project (the

"Project"

), located 100 km north of La Serena within the Atacama region in Incahuasi,

Chile. Drill hole 22MLDDH012 intersected

10.50 metres (m) of 3.76 grams per tonne (g/t) gold (Au)

and 3.83% copper (Cu), including 3.00 m of 2.30 g/t Au and 8.26% Cu, and 4.50 m of 6.03 g/t Au

and 2.19% Cu

; results are in Table 1.

This drill hole was collared at the 867 m level of the current

underground workings at Maria Luisa.

Program Highlights

Drill hole 22MLDDH012 is a new discovery north and west of historical underground workings. The

area has never been historically drilled or mined, follow-up work is underway to delineate the

scope and scale of this new discovery.

Rocks hosting high copper and high gold grades in 22MLDDH012 vary with depth (Table 1).

1.00 m of 0.88 g/t Au and 2.36% Cu

is from copper and iron oxide that is spatially

associated with a fault gouge zone.

10.50 m of 3.76 g/t Au and 3.83% Cu

is associated with a silicified

breccia zone

characterized by blebby to massive

copper sulphide (chalcopyrite)

and disseminated

pyrite.

At depth,

0.50 m

of

chalcopyrite-bearing intrusive

returned

6.46% Cu

.

Assay results are pending for four drill holes

that intersected intervals similar in appearance

to the high-grade breccia zone of 22MLDDH012 (Figures 1 and 2).

The Company has

developed 410 metres

of the NW-SE trending Maria Luisa Decline and is now

approximately 23 metres from the projected initial target length. Cross cuts to the SW will intersect

the vein system to support the proposed mining plan.

The decline advance also allows the Company to continue testing exploration targets from

underground drilling (Figure 3).

Alastair McIntyre, President and CEO, commented, "We are very encouraged with the discovery of this

new zone and the corresponding high-grade gold and copper assay results. The recent work at Maria

Luisa has focused on developing our underground decline system while establishing strategic

underground drill locations. This provides the opportunity to drill new targets efficiently to support

exploration and potential mine development with the added advantage of expanding our understanding

of the multi-vein system at Maria Luisa

."

The copper-sulphide-rich breccia intersected in 22MLDDH012 differs from the well-known near surface

oxide veins that have been historically mined at the Maria Luisa Project. Intensely silicified fragments

within this breccia also indicate fracturing of an existing hydrothermal system (Figure 2). While the

Company is still delineating the extent of the sulphide zone, there is indication that oxide and sulphide

mineralization are influenced by a larger fault system. The decline advance enables access to and

exploration of deeper, historically mined levels (Figure 1); the full extent of the gold -copper mineralized

material mined in level 841 is unknown to the Company to-date. Underground drilling from the decline is

planned to test the vertical continuity of structures and mineralization between the historically mined

levels 858 and 841, and lateral continuity between historical mining and the new discovery in

22MLDDH012.

* The decision to commence underground exploration and development at the Maria Luisa site 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 this decision.

Altiplano has generated over US$9.86 million from the recovery and sale (after processing costs) of 4.47

million pounds of copper with an average grade of 1.78% Cu (2018 Q1-2022 Q2). 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 at Maria Luisa, and the commissioning of the El Peñón fit-for-purpose mill and flotation plant

located 15 km from the Farellon site.

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 is no current mineral resource at Maria Luisa and

further exploration may or may not define a resource estimate (M. Dufresne, NI 43-101 Technical

Report, February 10, 2017). In addition, a decision to commence underground exploration and

development at the Maria Luisa site 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 this 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
