Steppe Gold Files Updated Preliminary Economic Assessment for the Tres Cruces Oxide Gold Project

Steppe Gold Ltd. (TSX: STGO) (OTCQX: STPGF) (FSE: 2J9) (‘ Steppe Gold ‘ or the ‘ Company ‘) is pleased to announce the filing of an updated preliminary economic assessment (the ‘ Technical Report ‘) regarding its 100% owned Tres Cruces Oxide Gold Project located in Peru (‘ Tres Cruces ‘).

Chairman and CEO of Steppe Gold, Bataa Tumur-Ochir commented, ‘We are delighted to announce this updated technical study for the Tres Cruces project. Tres Cruces is strategically located in a highly prospective geological belt that hosts the Lagunas Norte and La Arena mines, both with multi-million ounce gold production. The Tres Cruces deposit contains oxide plus sulphide indicated resources of 2,474,000 ounces with a grade of 1.65 g/t gold, inclusive of 630,000 ounces contained within leachable gold oxide mineralization with a grade of 1.28 g/t gold. Located in the La Libertad, Peru, surrounded by operating mines with the attendant infrastructure and talent pool, this asset shows great potential as a new production zone for Steppe Gold. We are excited with the strong economics confirmed by recent drilling and metallurgical testing, as well as the exploration potential across the license area.’


Infill drilling completed in 2022 confirmed continuity of mineralization. Metallurgical test work returned average recoveries of 82% Au, confirming design assumptions. Construction costs escalated 4.5% based on market data to reflect inflationary pressures. The initial capital expenditure estimate increased by $6 million to $131 million driven by equipment and labor costs. Operating costs rose 3.6% due to consumables, reagents, contract mining services. Life of mine operational expenditure estimate is now $297 million, up 3.6% from the Prelimary Economic Assessment dated effective March 14, 2022. Operational expenditure per tonne processed is now estimated at $19.93/t. At $1700/oz gold, the after-tax net present value is $158 million with 30.9% IRR. Despite the cost increases, the project economics remain robust with significant upside potential. Mine schedule unchanged with Phase 1 focused on maximizing value from the oxide gold cap. Experienced team continues to systematically advance the oxide project. Significant exploration potential remains with mineralization open at depth.

Mineral Resource Estimate

The current resource prepared by Jeffrey Rowe and James Gray (Advantage Geoservices), published in March 2021, was an update of the Technical Report by Lacroix and Associates (L&A) dated September 2012 for previous owner New Oroperu Resources (which is now a wholly-owned subsidiary of the Company). The estimate used the geologic models of lithology and alteration that were developed for the L&A resource, but divided the deposit by mineralization type (oxide, transition, or sulphide). Gold grade correlation based on geology was not readily apparent and the decision was made to use a 0.2 g/t grade shell as control for grade estimation. This shell was generated using an indicator estimation method. A total of 327 holes have been used for this estimate, of which 159 were RC holes and 168 were core holes. Sample grades were composited to a down-hole length of 3 m. Assays, subdivided by grade domain, were capped in a conventional manner prior to compositing.

Gold grades were estimated inside and outside the mineralized grade shell by ordinary kriging, into blocks with dimensions of 10m x 10m x 5m (X/Y/Z). Average density values were assigned by lithology based on 2,700 core density measurements.

The resource has been classified based on spatial parameters related to drill density and configuration, and the generation of an optimised pit. Blocks were initially classified as Inferred where the average distance to the closest three holes is within 80 m, and as Indicated where the average distance to the closest three holes is within 50 m. Pit optimization included variable cost and recovery values dependent on mineralization type. All material included in the Mineral Resource Estimate is contained within the optimized shell.

The Technical Report only considers mining and processing of leachable oxides and transition materials from the Indicated and Inferred resource categories. Sulfide mineralization is considered a future opportunity and does not currently factor into mine planning, processing or financial results as reported in this PEA.


The Technical Report results are summarized for purposes of this press release. Further details on the Technical Report are available under the Company’s profile on SEDAR+ at and on the Company’s website at

The Technical Report is preliminary in nature and it includes inferred mineral resources that are considered too speculative to be used in an economic analysis except as allowed for under National Instrument 43-101 – Standards of Disclosure for Mineral Projects (‘ NI 43-101 ‘). There is no guarantee that the inferred mineral resources can be converted to Indicated or Measured mineral resources, and as such, there is no guarantee the project economics described in this release will be achieved.

The following persons, all of whom are qualified persons under 43-101, have approved the disclosure contained within this release:

Name of Qualified Person Company Qualification John Woodson M3 Engineering & Technology Corporation P.E.

The Technical Report was prepared in accordance with NI 43-101. The study was prepared by M3 Engineering and Technology Corporation of Tucson, Arizona and Arequipa, Peru, in cooperation with Nilsson Mine Services of Pitt Meadows, BC, Transmin Ltd., of Lima, Peru, Advantage Geoservices Ltd. of Chilliwack, BC, and Jeffrey Rowe of Surrey, BC.
