American Pacific Mining Recaps 2019 and 2020 Drill Results from the Madison Copper Gold Project

VANCOUVER, British Columbia, July 20, 2021 (GLOBE NEWSWIRE) -- American Pacific Mining Corp (CSE: USGD / FWB: 1QC / OTCQB: USGDF) (“American Pacific” or the “Company”) is pleased to recap the recently compiled results from the 2019 and 2020 drilling programs conducted by Kennecott Exploration Company (“Kennecott”) on the Company’s Madison Copper Gold Project (the “Madison Project”), located in Montana, USA. The Madison Project encompasses a historical mining district and past producer in western Montana, USA.

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

“These drill results from the 2019 and 2020 campaigns encountered a variety of styles of mineralization including jasperoids, veins and skarns, all of which can contain strong copper and gold values,” states Eric Saderholm, President of American Pacific. “The 2021 drilling and exploration program is currently in progress at Madison with a diamond drill and crews on-site. Mineralization continues to be open down-plunge and lateral to modelled mineral bodies. Our joint venture partners, the Rio Tinto Group, have developed an innovative and unique structural interpretation at Madison and several planned holes will test these theories.”

The 2019 drill program consisted of fourteen diamond drill holes totaling 4,013.93 m. Drill holes MADN0001 to MADN0006 targeted Porphyry style mineralization and drill holes MADN0007 to MADN0014 targeted the down dip and easterly strike extension to the known Madison Skarn mineralization.

The 2020 drilling program consisted of nine diamond drill holes totaling 2012.44 m, which mainly targeted extensions of skarn and associated jasperoid mineralization. Significant intervals from both the 2019 and 2020 drill holes are listed in Table 1 below.

Sampling, Laboratory and Quality Assurance/Quality Control Program

All drill core was logged and photographed prior to sample selection. Selected sample intervals honor lithological and visible sulfide boundaries and split in half along the core axis with a diamond saw. Half-core samples were submitted to ALS Laboratories in Elko, Nevada, USA (17025 accredited), for preparation and analysis. Drill core samples were analyzed for 48 elements by four-acid digestion of a 0.25-gram sample followed by an ICP-MS (inductively coupled plasma mass spectroscopy) finish. Gold (Au) was also analyzed by fire assay of a 30-gram sample followed by an ICP-AES (inductively coupled plasma atomic emission spectroscopy) finish.

As part of the Rio Tinto Exploration quality assurance/quality control (QA/QC) program, independently certified control samples (standard and blank pulp samples), coarse blank samples and core duplicate samples were inserted into the sample stream in each analytical batch. The control sample results are monitored to ensure proper QA/QC.
