Monument Peak Copper-Silver-Gold Project, Idaho, USA
The Monument Peak Project consists of 69 claims covering approximately 1,380 acres (~558.5 hectares). It is an exploration-staged, high-grade, copper-silver-gold project, which covers two small past producing copper mines: Jackson and Hungry Hill. Sporadic development and production in the area occurred primarily during the early 1900’s, with some additional development in the 1950’s. The most recent exploration occurred during the 1970’s and 1980’s.
Mitchel (1972) described the Cu-Ag-Au mineralization at Monument as having “unusual continuity” in association with structural zones within sericitic quartzites, which can be traced along 3,200 m strike that vary from 3 to 6 m width.
The mineralization is described (Lavery, 1988) as “syngenetic and fits a volcanic-hosted (massive) sulfide model … where … the copper-mineralized section might be as much as 175 feet thick”.
Project highlights follow (from North to South):
- North Showing: grab samples to 0.57% Cu, 248 g/t Ag, 57.5 g/t Au;
- Jackson Adit: grab samples to 13.6% Cu, 2,589 g/t Ag, 17.1 g/t Au;
- Chip Sample: 3.0 m of 7.03% Cu, 109 g/t Ag
- Chip Sample: 1.8 m of 3.11% Cu, 101 g/t Ag
- Chip Sample: 6.1 m of 4.32% Cu, 99 g/t Ag
- Anderson Occurrence: grab samples to 3.9% Cu, 89 g/t Ag, 2.5 g/t Au.
- Hungry Hill Mine (2 km east of main trend): 2.4 m of 17% Cu.
The company intends to complete a brief field program during the spring of 2021 and thence prepare a NI 43-101 Technical Report documenting all historical and recent exploration on the property.
The fall 2020 program, undertaken by DG Resource Management Ltd., included the collection of 56 rock samples to confirm historic results. The field work confirmed both the presence of significant Cu, Ag mineralization, but also the presence of gold mineralization.
Highlights are as follows:
- A total of 56 rock samples from three main areas over 3,200 m strike and from the separate Hungry Hill Mine, and
- Arithmetic average of all grab samples 2.34% Cu, 57.6 g/t Ag, 0.68 g/t Au.
Field crews visited four known mineral occurrences (Jackson/Baker, Hungry Hill Mine, Anderson and North Showing) and confirmed the high-grade Cu-Ag (+/- Au) mineralization at all locations. Outcrop is sparse throughout the property and commonly only exposed by historic workings. Observed mineralization style and grade is similar across all showings, with notably higher copper grades (up to 20.9% Cu) at Hungry Hill, while the North Showing had the highest gold values (up to 11.4 g/t Au). High grades of silver (greater than 80 g/t Ag) were associated with all mineral occurrences.
Sample results are highlighted below:
- North Showing: caved adit with abundant copper oxide staining around adit portal;
- Baker/Jackson: several large trenches (to 50 m length); open adit of unknown length within folded schists and quartzites, abundant copper oxide staining, hematite and quartz veins;
- Anderson Showing: numerous trenches and pits; and
- Hungry Hill Mine: Two adits with road to base, historical mine cart system. Abundant bornite/quartz veins occur within sheared chloritic schists at adit portal.
Mineralization is primarily hosted by quartzites, phyllites and schists of the Precambrian Belt Series and is associated with copper oxide stain, hematite and quartz veins.

Quality assurance/quality control
All rock samples collected (grab) as well as quartz blanks and certified reference materials were shipped by ground to Activation Laboratories Ltd. in Kamloops, B.C., for multi-element analysis (including silver) by aqua regia digestion with ICP-OES finish (code 1E3) and gold analysis by fire assay with AA finish (package 1A2B-50). Over-limit results for gold, silver, copper, lead and zinc were determined by the relevant analytical package.
Management cautions that prospecting surface rock sample assays, as presented herein, are selective by nature and represent a point location and therefore may not necessarily be fully representative of the mineralized horizon sampled.
