Orla Mining Ltd. 100 % Indirect
Gold Standard Ventures Corp. owns 100% of the South Railroad project, located in Elko, Nevada.

On August 12, 2022, Orla Mining Ltd. completed the previously announced acquisition of Gold Standard by way of court-approved plan of arrangement (the "Transaction"). As a result of the completion of the Transaction, Orla acquired all of the issued and outstanding Gold Standard Shares and Gold Standard became a wholly-owned subsidiary of Orla.

Deposit Type

  • Carlin-type


Summary:

The Railroad-Pinion property includes demonstrated Carlin-type gold mineralization in at least four deposit areas: North Bullion, Pinion, Dark Star, and Jasperoid Wash. These deposits are similar in setting and style to that of other deposits in the region, including Rain and Emigrant (Koehler et al., 2014; Norby et al., 2015; Turner et al., 2015; Dufresne and Koehler, 2016). Mineralization occurs mainly as finely disseminated, submicroscopic gold in largely stratiform bodies in Devonian, Mississippian, and Pennsylvanian- Permian rocks. The following subsections describe the mineralization in the North Bullion, Pinion, Dark Star, and Jasperoid Wash deposits and are modified from Dufresne and Nicholls (2016; 2017a; 2017b; and 2018).

The Railroad-Pinion property has two adjacent parts, the North Railroad portion (“North Railroad”), which includes POD, Sweet Hollow, and North Bullion (collectively called the North Bullion deposits, or the North Bullion area), and the South Railroad portion (“South Railroad”), which includes Dark Star, Pinion, and Jasperoid Wash.

North Bullion Deposits
The North Bullion deposits, which includes North Bullion, POD, Sweet Hollow and South Lodes zones, contains Carlin-type disseminated-gold mineralization that is largely not exposed at the surface. The bulk of the geological understanding and interpretation of the North Bullion deposits has come from core drilling that was guided by interpretations of gravity and CSAMT ........


Mining Methods

  • Truck & Shovel / Loader


Summary:

The FS includes mining at both the Dark Star and Pinion deposits; both are planned as open-pit, truck and shovel operations. The truck and shovel method provides reasonable costs and selectivity for these deposits.

The production schedule considers the processing of material by ROM. All ROM material will be dumped in place directly on the ROM leach pad. Monthly periods were used to create the production schedule with pre-stripping starting in Dark Star at month -6. Start of ROM processing is assumed to be month 2.

The total Dark Star mining rate would ramp up from 20,000 tons per day to about 80,000 tons per day over a period of 6 months. A maximum of 109,000 tons per day is used in the production schedule during the peak mining of deeper Dark Star material. Pre-production mining is planned to start in Dark Star North and then progress to Pinion in Year 1. The maximum mining rate required in Pinion is 126,000 tons per day.

The FS has assumed owner mining to keep the cost lower than it would be with contract mining. The production schedule was used along with additional efficiency factors, cycle times, and productivity rates to develop the first principle hours required for primary mining equipment to achieve the production schedule. Primary mining equipment includes drills, loaders, hydraulic shovels, and 200-ton capacity haul trucks.

Waste storage facility designs were created for the FS to contain the material that is not process ........
