Update on Chile Project

CARSON CITY, Nev., Jan. 27, 2026 /PRNewswire/ -- American Lithium Minerals Inc. (OTC: AMLM) ("AMLM" or the "Company"), announced an update of its transaction with Aeramentum Resources Limited ("AEN") who has been actively progressing exploration plans and in summary:

Figure 1) Oxide copper/limonite/Malachite from Calabozo Prospect (sample no. 20011502) Returned 681 g/t Ag and 0.68% Cu, 0.43g/t Au (11/20/2025)

Ratification of Grande Plata Silver Project Deal: AEN is working to complete the contract with AMLM. The deal was originally negotiated and completed when the silver price was $33/oz compared to more than US$100/oz today.
Further high-grade silver from sampling at Grande Plata: The AEN geologists were on-site at Grande Plata in November 2025, conducting sampling and reconnaissance. In line with similar grades achieved across the >7.5km strike of exposed Ag-Cu-Au veins, recent sampling returned encouraging grades in a number of locations exceeding 680gt Ag and 3% Cu (see summary table below).
Ahead of planned diamond drilling in March, mapping and trenching is planned, along with upgrading the roads and drill pads to ensure the site is prepared for the drilling program.

Table 1: November 2025 reconnaissance sampling

Sample Number	Prospect Name	Sample Type	Au (g/t) AAS	Ag (g/t) GRAV	Cu (%)	Mo (g/t)	Comments
20011501	Calabozo	Copper oxides- dominated outcrop	0.02	39	0.42 %	2.9	Moderate grade Ag/Cu
20011502	Calabozo	Limonite with copper oxides	0.43	681	0.68 %	20	High grade silver
20011503	Cumbre	Copper oxides- dominated outcrop	0.36	341	3.30 %	20.6	High grade Cu, Ag
20011504	San Jose	Copper oxides- dominated in historic pits	0.01	2	2.02 %	2.0	High grade Cu, low silver
20011505	San Jose	Copper oxides- dominated in historic pits	0.42	421	0.18 %	217	Relatively high Mo grade, points to porphyry nearby?
20011506	San Jose	Limonites with copper oxides in historic pits	0.070	600	6.67 %	16.3	High grade silver

A review of geological reports continues to provide encouragement, with the potential for broad, moderate to high grade intersections based on surface mapping and past trenching results which show an altered dacitic tuff unit, which hosts the mineralised veins, up to 100m wide in some locations such as Calabozo. Mineralisation is from surface (refer to Figure 2) with previous trenching results including:

6m @ 407g/t Ag, 2.94% Cu, 0.72g/t Au (Calabozo, Figure 3a, b)
6m @ 199g/t Ag, 1.44% Cu, 0.36g/t Au (Calabozo, Figure 3a)

As part of the preparation for drilling at the Silverado Prospect, previous tenement rights holders (2020-2022) Rugby Mining conducted some channel sampling with results including:

Section 6657120N: 2.5 m @ 135 g/t Ag, 0.64 % Cu, 0.14 g/t Au and 5.80 % Pb
Section 6657120N: 1.5 m @ 591 g/t Ag, 2.47 % Cu, 0.10 g/t Au and 4.95 % Pb
Section 6657152N: 1 m @ 1,550 g/t Ag 2.91 % Cu, 0.51 g/t Au and 6.32 % Pb
