Idaho Champion Gold Mines Canada Inc. Reports the Results from Its 2020 Diamond Core Drilling Campaign At Its 100% Controlled Champagne Gold Project Near the City of Arco, Butte County, Idaho
Idaho Champion Gold Mines Canada Inc. reported the results from its 2020 diamond core ("Core") drilling campaign at its 100% controlled Champagne Gold Project ("Champagne") near the city of Arco, Butte County, Idaho. 2020 Champagne Drilling Highlights: Drill hole DDH-CC-20-02 intersected 1.04 g/t gold equivalent ("AuEq") for the interval 123.14-166.12 m (42.98 m core length), including 1.22 g/t AuEq for the interval 123.14-157.06 m (31.93 m core length). Drill hole DDH-CC-20-02 was collared at Mine Hill in the approximate center of the unmined 300 m interval between the North and South Pits (Bema Gold c. 1989-90). This mineralized interval is associated with shallow induced polarization anomalies in chargeability and resistivity as reported in the Idaho Champion press release dated Feb. 2, 2021. Champagne Drilling Technical Summary: The 2020 core drilling program consisted of seven (7) diamond drill holes totaling 2,818 Metres (Fig. 1). Five core holes (DDH-CC-20-01 through DDH-CC-20-05) were positioned on Mine Hill in the vicinity of the North and South Pits and two core holes (DDH-CC-20-06 and DDH-CC-20-07) were located further north near the Ella Mine breccia vein. Three holes (DDH-CC-20-01, -02, -07) intersected promising precious metals mineralization, with the strongest presence of gold and silver intersected in DDH-CC-20-02. The spatial relationships of these three holes to results of the recently completed induced polarization (IP) survey are represented in Figs. 2-3. An inferred low-angle detachment fault represented in Fig. 2 is interpreted to have displaced the shallow IP anomaly at Mine Hill from a larger and deeper anomaly 800 m west of Mine Hill. DDH-CC-20-01 (Fig. 4) was inclined westward beneath the central part of the North Pit across a series of mineralized and altered breccia and fractured intervals. The intervals represent a sheeted pyritiferous breccia zone, the upper oxidized portion of which was mined for gold and silver in the North Pit. Below the pit floor, the breccia intervals in the intercept were found to be separated by intervals of less-altered andesite. DDH-CC-20-01 is interpreted to have progressed from the very top of the hydrothermal mineralizing system down into increasingly gold-bearing parts of the system. This gradient of increasing gold with depth also correlates to intervals of increased levels of anomalous pathfinder metals (principally As, Hg, Sb, and Bi).
DDH-CC-20-02 (Fig. 5) was sited to test the projected trace of the Last Chance Zone, which had historically been exploited for oxide-silver (Horn Silver Mine) and deeper lead-zinc-silver sulfide mineralization. The reported common occurrence of accessory famatinite (copper-antimony sulfosalt) and aikinite (copper-bismuth sulfosalt) with the sulfide ore is also of exploration interest. The Last Chance Zone was intersected between drilling depths of 123.14 to 166.12 Metres and is comprised of strongly pyritized breccia and brecciated andesite with sulfide intervals approaching semi-massive character. The results show that the zinc and lead values appear to be tapering off down hole, but anomalous gold content continues to depth, as does silver and copper. The pathfinder metal mercury reaches very high levels with scattered intervals of strong arsenic and scattered intervals of anomalous antimony and bismuth. A fault that is interpreted as a low-angle detachment structure was encountered below the intersection of the Last Chance Zone. DH-CC-20-07 (Fig. 6) was designed to test the Ella Mine breccia vein but is interpreted to have instead pierced the detachment fault at shallow depth. The hole was advanced through propylitically altered footwall ash-fall and crystal tuff units in an effort to penetrate the eastern edge of the IP anomaly on Lines 4 and 5. Strong sericite-silica alteration and well-developed mosaic brecciation was intersected beginning at a depth of 340 m. The pyrite content increased to 3 - 8% with the sericite and silica alteration and is accompanied by anomalous silver, zinc, lead and arsenic (as well as weakly anomalous gold values). At depths of 441.96 to 452.63 Metres, anomalous silver (up to 42.3 g/t), copper (up to 0.22%), and anomalous gold (up to 0.107 g/t) occur within a brecciated interval. Zinc, lead, and arsenic are also anomalous within this interval. At a depth of 475 m, the hole returned to dominantly propylitic alteration with diminished pyrite content. The direction and angle of the hole suggests that only the outer-most edge of the IP anomaly was intersected. Quality Assurance/Quality Control Procedure Idaho Champion Gold adheres strictly to a regimented drill core handling and processing procedure. Core from the drill rig(s) is logged for lithology, mineralization, structure, alteration, and veining. During the logging process 1 to 2 meter samples are delineated by company geologists. Core is then photographed and sawn in half. Following sawing, individual samples are extracted from core boxes and inserted into individual sacks with a unique waterproof sample number tag and sealed. The remaining half-core is left in core boxes for Quality control (QC) samples are inserted into the sample stream such that there is one QC sample for every ten drill core samples. These QC samples consist of certified standards (known metallic content) and blanks (known barren of metals). Two styles of blank material were used: a coarse blank and a pulverized blank. QC sample insertions alternate between standard and blank. The first sample shipment was delivered to ALS Geochemistry's facility in Elko, NV. All subsequent sample shipments were delivered to American Assay Labs (AAL) in Sparks, NV. ALS and AAL conform to ISO 17025 requirements. All drill samples and coarse blanks arecrushed to 70% passing 2mm at the assay lab, and 1 kg material is split and pulverized to 85% passing 75 micron. All samples are processed by 30 gram fire assay- Inductively coupled plasma optical emission spectrometry (ICP-OES). Samples are additionally analyzed for 35, 36, or 61 multi-element analysis by ICP-OES and/or inductively coupled plasma mass spectrometry (ICP-MS). Samples containing Au or Ag above detection limits by ICP-OES analysis are automatically re-analyzed by fire assay with a gravimetric finish. All drill intervals reported in this release are calculated using a 0.10 g/t gold cut off grade and a maximum of 3 Metres consecutive waste.
