American Pacific Mining Presents the First Historical Compilation of Rock Geochemistry at the Madison Copper Gold Project

VANCOUVER, June 09, 2021 - American Pacific Mining Corp. (CSE: USGD / FWB: 1QC / OTCQB: USGDF) ("American Pacific" or the "Company") is pleased to announce the results of recently compiled rock sample geochemistry for gold and copper at the Company's Madison Copper Gold Project (the "Madison Project"), located in Montana, USA. This comprehensive dataset has been compiled from all the available current and historical Kennecott Exploration and Broadway Gold data for the first time. All sample locations and data are located on land controlled by American Pacific.

The Company's wholly-owned Madison Project is currently under an earn-in with an option to joint venture agreement, whereby Kennecott Exploration Company ("Kennecott"), part of the Rio Tinto Group ("Rio Tinto"), may spend $30 million USD to earn up to 70% (see news release dated June 26, 2020).

Rock Geochemistry Compilation

American Pacific has compiled the historic surface rock samples and they are shown on the maps in Figures 1 and 2 below. This is the first time all of the historic data has been compiled and put into a visual format.

Eric Saderholm, President of American Pacific stated: "This newly compiled dataset shows the broad occurrences of mineralization found at the Madison Project. It is impressive and clearly shows high-grade gold and copper numbers distributed throughout the property. The higher-grade mineralization is hosted in a large array of different styles and textures including high-level quartz veins, iron-rich skarns, copper and gold bearing jasperoids and massive sulfides. The presence of these grades and values furthers the interest in the Madison Project and is a main driving component for accelerated exploration on rapidly evolving targets. Kennecott Exploration has mobilized equipment to Madison and are currently drilling. We anticipate a productive exploration year in 2021."

Sample security

The measures taken to ensure sample security Samples were submitted to the ALS Global lab by the company personnel following the guidelines and procedures of the Rio Tinto Exploration (Kennecott). Only authorised personnel have attended the samples.

Analysis Suite for QA/QC

ALS Global ran ALS_RIODISPXAU_SPEC; ALSRIODISPXAU+RIOSPEC Supertrace multielement (ME-MS61L); Au by fire assay (Au-ICP21); RTX pXRF Cr, Nb, Si, Ta, Ti, Y, Zr(p-XRF-30 RT/p-XRF-30NDL); an RIOSPEC VNIR/SWIR spectra (TRSPEC-20/INTERP-11).

Audits or reviews

The results of any audits or reviews of sampling techniques and data were reviewed by Kennecott Exploration personnel. Internal review of the drilling results by the company management is routinely used through the course of the project.

Standards

Two certified reference materials were use as standards for QA/QC and were provided by ALS Global and obtained from OREAS based in Australia. These standards were OREAS 504c and OREAS 524. These standards as well as blanks were inserted into the assay stream by Kennecott Exploration personnel with no input from American Pacific Mining.
