American Pacific Mining Reports Unreleased 2019 Drill Results from the Madison Project Highlighted by 74m at 1.16 g/t Au, Including 3.46m at 17.71 g/t Au

 

 

 

 

 

American Pacific Mining Corp (CSE: USGD) (FWB: 1QC) (OTCPK: USGDF) is pleased to announce results from the 2019 drilling program conducted by Kennecott Exploration Company on the recently acquired 100%-owned Madison copper-gold project, USA The Madison Project encompasses a historical mining district and past producer in western Montana. The Madison Project is currently under an earn-in, joint venture agreement, whereby Kennecott Exploration Company, part of the Rio Tinto Group may spend $30 million USD to earn up to 70% (see news release dated June 6, 2020).

 

“High-grade, skarn-related massive sulfide mineralization at Madison has been extended 112 meters down-plunge in Hole MADN0012, 108 meters laterally in Hole MADN0010 and 43 meters down-dip in Hole MADN0011 as a direct result of the 2019 drilling results” states Eric Saderholm, Company President. “Historical drilling has produced some very high-grade skarn intercepts in the past, including 30.18 meters at 24.50 g/t Au in Hole UG17-05 and 61.63 meters at 6.97% Cu in Hole C05-06 and strong mineralization potential is open both down-dip and lateral to the existing drilling and modeled mineralization. All new drill sites are now completed for the 2020 Madison drilling campaign. Our new joint venture partners, Rio Tinto, have developed an exploration program to test extensions and offsets to the skarn-related mineralization. American Pacific is pleased to be a part of these endeavors.”

 

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.

 

2019 Highlighted drill results include (see Table 1 below for full results):

 

  • MADN0010: cut 1.16 g/t Au over 74m (including 0.18% Cu and 17.71 g/t Au over 3.46m)
  • MADN0011: cut 1.42 g/t Au, 2.41% Cu and 44.50 g/t Ag over 2.54m
  • MADN0013: cut 2.60 g/t Au and 0.20% Cu over 9.22m

 

MADN0010 and MADN0011 both intersected high-grade mineralization associated with alteration associated with skarn related sulfides dominated by pyrrhotite and pyrite in the limestone and dolomite host rocks within the upper Devonian Jefferson Formation, a noted ore host time-horizon throughout the western USA.

Previous Drilling by Broadway Gold Mining Ltd.

 

Notable drill intercepts from MADN0010 are considered a significant step-out from high grade underground drilling reported in Press Release dated June 15, 2017 by Broadway Gold Mining Ltd. The results from this program include:

 

  • 1.098% Cu and 1.651 grams per tonne Au (g/t) over 24.30 meters in hole UG17-04
  • 2.717% Cu and 2.466 grams per tonne Au (g/t) over 7.32 meters in hole UG17-04
  • 0.391% Cu and 24.497 grams per tonne Au (g/t) over 30.18 meters in hole UG17-05
  • 0.276% Cu and 68.608 grams per tonne Au (g/t) over 4.57 meters in hole UG17-05
  • 0.384% Cu and 41.648 grams per tonne Au (g/t) over 10.97 meters in hole UG17-06

 

Interval length reported by Broadway Gold are reported as drilling length. True width of mineralization has not been determined.

 

Underground drilling defined a 30.00 m by 16.50 m ovoid sulfide body immediately beneath the 600 level. Drill hole results suggest that gold and copper mineralization continues to depth below the 600 level as shown in the accompanying drill plan (see also 

http://broadwaymining.com/projects/current-exploration/).  

 

Since the existing underground infrastructure does not allow for deeper drilling from within the mine workings, surface hole C17-20 was drilled to test the down dip extension of the mineralized ovoid body a further 40 meters below the 600 level. This hole intersected massive sulfides parallel to the short axis of the sulfide body, which indicates that the body remains open to depth. Drill hole C17-20 intercepted 23.8 meters of 1.247 g/t Au and 1.843% Cu from a depth of 130.8 to 154.6 meters, including 3.7 meters of 2.156 g/t Au and 3.214% Cu from a depth 146.3 to 150.0 meters.

 

The results from these three underground holes and two previously released holes suggest a zoning within the sulfide body. The southern section appears to contain a more gold-rich zone while the northern section appears to contain a more copper-rich zone. The last sample in Hole U17-04 ran 8.27 g/t Au suggesting mineralization extends past the end of the hole. Gold and copper mineralization extended above and below the massive sulfide into the epidote-garnet-diopside skarn and intrusive.

 

Mineralization within the massive sulfide is described as 1% to 80% pyrite, 0% to 20% pyrrhotite, 0% to 5% chalcocite, 0% to 5% chalcopyrite and 0% to 5% bornite. Mineralization within the epidote-diopside-garnet skarn and Radar Creek intrusive is described as local chalcocite, native copper and copper oxides.

 

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 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.
