The Golden Chest deposit is recognized as an “intrusive related” orogenic gold-quartz vein system by IDR geologists. However, recently there has been the suggestion that the Golden Chest deposit type could be a Reduced Intrusion-Related Gold System (RIRGS). The RIRGS deposit classification is already mired in confusion over nomenclature. It should be remembered that each ore deposit has its own specific and unique characteristics and not all deposits exhibit all characteristics of any particular classification. Deposit models are sets of guidelines, not absolute parameters. No one model will describe multiple deposits, one model describes one deposit. That being said, there is considerable overlap between the two deposit model types and the Golden Chest deposit has characteristics of both orogenic and RIRGS model types. This report will continue to use the orogenic deposit classification for the Golden Chest. The primary geological control to mineralization at the Golden Chest is the Idaho Fault. The Idaho Fault separates the hanging wall (Prichard Formation-Member H) from its footwall (Prichard Formation- Member G). The Idaho Fault acted as the conduit for the mineralizing fluids that produced most of the veins at the Golden Chest Mine. The veins are generally stratiform and conformable to the Idaho Fault and are centered along the Idaho Fault to form a sub-parallel, stacked vein set. The alteration is generally weak and mostly occurs immediately adjacent to the veins. S ........

The Golden Chest Mine is comprised of an underground mine, an open pit mine, and an exploration property located about 1.5 miles east of Murray, Idaho. T

Open Pit Mining Operations
In 2022, IDR continued its open pit mining operation which commenced in August of 2016. Mining in the Klondike pit was completed in June. A small pit on the Jumbo vein was mined intermittently during 2022 also. A total of 8,400 tonnes of ore at average grade of 4.55 gpt gold and 80,200 tonnes of waste were mined during the year. Ore tonnes and grade in the Klondike Pit were lower than modeled because of unmapped, historic stopes in the Klondike where high-grade material had been mined out by the old- timers.

Mining Operations - Underground
The Golden Chest is a ramp access mine that was developed as a modern rubber-tire operation. All material is transported to the surface via two underground haul trucks and occasionally a 4.6 m3 load-haul-dump underground loader (LHD). Stope rounds are transported to bays using 1.5 m3 LHD’s. Drilling advance of stope rounds is accomplished with two Tamrock Quasar single boom jumbo drills. An electric over hydraulic twin boom jumbo drill and small section (2.7 m by 2.7 m) bolting machine have been procured to further increase operational efficiencies. The main ramp has a width and height of 4 m by 4.6 m respectively. All ventilation/secondary escape raises are mined 3 m by 3 m. Stope dimensions are 3 m by 3 m.
