In June 2017 Revival Gold assembled a 100% interest in the original Arnett Gold Project through earn-in and purchase agreements. In September 2017 Revival Gold announced the execution of an earn-in and related stock purchase agreement with Meridian Gold Company, a subsidiary of Yamana Gold Inc., by which Revival may acquire a 100% interest in Meridian Beartrack Co., owner of the past-producing, open pit heap leach Beartrack Gold Mine.

Summary:
Beartrack
Gold mineralization at Beartrack exhibits many of the characteristics of the class of gold deposits known as mesothermal, orogenic, or shear zone-hosted deposits. In these deposits, gold is deposited at crustal levels at depths of 3 km to 20 km (1.9 mi to 12.4 mi) and at temperatures from 200°C to 400°C. Deposits may have a vertical extent of up to 2 km and lack pronounced zoning. Gold-bearing quartz veins and veinlets with minor sulphides crosscut a wide variety of host rocks and are localized along major regional faults and related splays (Robert, 2004; Goldfarb and Groves, 2015). The wall rock is typically altered to silica, pyrite, and muscovite within a broader carbonate alteration halo (Ash and Alldrick, 1996).
Mineralization at Beartrack consists of quartz-pyrite-arsenopyrite (gold-iron-arsenic-sulphur) veins and veinlets occurring in a broad halo of sericitic alteration related to the PCSZ. The PCSZ exhibits both brittle and ductile deformation and is interpreted to be a deep-seated regional structure that has been active for a protracted period of time. Mineralization does not exhibit any zonation over 750 m (2,460 ft) vertically. All these characteristics are typical of mesothermal gold deposits.
In the case of gold mineralization at Beartrack, the characteristics and controls of mineralization are reasonably well known. The primary control on mineralization is the regional, north-northeast trending PCSZ and an important secondar ........
Summary:
The Beartrack Arnett PEA considers mining two deposits: Beartrack and Arnett. Beartrack is a brownfield operation with two open pits: Beartrack North Pit and Beartrack South Pit. Arnett is a greenfield operation located approximately 8 km (5 mi) from Beartrack. Beartrack will be mined first followed by Arnett.
The PEA assumes conventional open pit mining using a owner-operated equipment fleet, with mineralized material from both deposits treated at the Beartrack site. The mining operations will have a seven-year life, with half a year of pre-production (PP1).
The Project has been designed as a conventional truck-shovel operation with 62 t (68 ton) trucks and 10 m3 (13 yd3) shovels. To balance stripping requirements while satisfying the process plant requirements, the pit design includes five phases for Beartrack: two phases in the North Pit and three in the South Pit. For Arnett, the pit design includes two nested phases.
The smoothed final pit designs contain approximately 15.9 Mt (17.5 Mton), 6.2 Mt (6.8 Mton) and 8.1 Mt (9.0 Mton) of mineralized material for Beartrack North Pit, Beartrack South Pit and Arnett, respectively. The Project contains a combined total of 30.2 Mt (33.3 Mton) of mineralized material and 85.6 Mt (94.3 Mton) of waste for a resulting stripping ratio of 2.8:1. Within the 30.2 Mt (33.3 Mton) of mineralized material the average grade is 0.873 g/t (0.025 oz/ton) AuFA.
The Beartrack deposit is mined in five pha ........

Reserves at May 12, 2022:
Base case cut-off grades at $1,800/oz Au are approximately 0.48 g/t Au and 0.18 g/t AuCN for mill and heap leach, respectively for Beartrack and approximately 0.24 g/t Au for heap leach for Arnett. Heap leach cut-off grade and mill cut- off grade varies based on gold price.
