Bluestone Advances Basic Engineering at Cerro Blanco, Provides Project Update and Plans for 2021
January 26, 2021 – VANCOUVER, BRITISH COLUMBIA – Bluestone Resources Inc. (TSXV:BSR | OTCQB:BBSRF) ("Bluestone" or the "Company") is pleased to provide an update on the Company’s activities during 2020 at its 100% owned Cerro Blanco gold project located in southern Guatemala (“Project”), and provide an outlook on plans for 2021. During 2020, a Project Readiness Update (“PRU”) was undertaken which involved a thorough and extensive review of the current mine plan, engineering, process flow sheet, capital and operating cost estimates, along with the execution strategy. The PRU will be further optimized in H1 2021 following the completion of an updated mineral resource estimate and mine plan to incorporate the recently completed 2020 drill program.
- $30 million credit facility with Natixis secured (a lending bank in connection with Project finance).
- Jack Lundin appointed as CEO and to the Board of Directors.
- Several important optimization and trade-off studies completed.
- Completed a successful C$92 million equity financing to fund advancement of the Project.
- Technical, environmental, and social due diligence for the Project Finance banks completed.
- Completed basic engineering.
- Completed over 15,000 meters of infill drilling that returned the highest-grade intercept (1,380 g/t gold & 2,194 g/t silver) ever drilled at the Project.
Jack Lundin, CEO, commented, “2020 was no doubt a challenging year but from the onset of the pandemic we were able to adapt quickly to this new environment and are feeling motivated entering into 2021. Despite the COVID-19 pandemic and the travel restrictions in place in Guatemala for the last eight months of the year, the commitment and hard work of our Guatemalan team, together with the firm support of both the Guatemalan government and local stakeholders, allowed us to advance the Project in several key disciplines which included completion of basic engineering, validation of the underground mine plan, as well as the 2019 Feasibility Study (“FS”) production profile over the life-of-mine. Additionally, we were able to successfully complete a 15,000 meters infill drill program in the South Zone in December. We have been supported with a steady flow of great results, including 15 meters grading 21.6 g/t gold and 52 g/t silver plus truly bonanza grades of up to 1,380 g/t gold and 2,194 g/t silver over 1.2 meters (see press releases June 9, 2020 and November 19, 2020).”
Regarding outlook for 2021, Mr. Lundin added, “The Project execution team will continue to work to optimize the Project as the Company waits for the lagging assay results. We have seen the upside potential in the near surface high grade intercepts and are confident we will be able to increase the mine life at Cerro Blanco with the rest of the results. As we wait, additional studies are currently being undertaken that look at a variety of development options. Our focus remains on maximizing the potential benefits at Cerro Blanco for all of our stakeholders.”
Project Readiness Update
The FS envisioned a 1,250 tonne per day (“tpd”) mine producing approximately 113,000 ounces of gold a year over an eight-year mine life at an AISC of $579/oz (see NI 43-101 technical report titled “Feasibility Study NI-43-101 Technical Report Cerro Blanco Project Guatemala”, prepared by Maz Mohaseb, P.Eng., Michael Makarenko, P.Eng., Kelly McLeod, P.Eng., Richard Boehnke, P.Eng., Mike Levy, P.E., Garth Kirkham, P.Geo., Hhan Olsen, P.G., CPG and Bryan Ulrich, P.E., dated January 29, 2019 and filed on www.sedar.com under Bluestone’s SEDAR profile). Since that time, Bluestone has completed an infill drill
program in the North Zone of the deposit and an updated resource estimate which added over 200,000 ounces of gold in Measured and Indicated categories (see Company press release November 6, 2019). Additionally, with the onboarding of key Project development personnel, the Company has conducted an in-depth technical analysis of the entire Project and completed basic engineering and trade-off studies to optimize future operations.
The PRU is intended as an interim study to build off the compilation of geological, engineering, and hydrological studies performed during the FS. Further optimizations to the mine plan are expected following an updated resource estimate in H1 2021. The mine plan review to date, along with the decision to purchase the mining mobile fleet during the construction period, combined with the additional detail of basic engineering, is expected to result in moderate increases to capital and operating costs compared to the FS; however, the impact of an increased gold price, additional ounces recoverable, and other optimizations are expected to offset this, resulting in robust Project economics in line with the FS.
Highlights below are provided as an interim update and are therefore preliminary in nature, incorporating results of recent basic engineering and various optimization and trade-off studies. The reader is cautioned that the following highlights are considered Forward Looking Statements and subject to risks and uncertainties that may cause the actual results to differ materially from those discussed (see Forward Looking Statements at the end of this press release).
Unless otherwise indicated, all dollar amounts are stated in U.S dollars (“$”). Base case was completed at
a gold price of $1,500/oz and a silver price of $20/oz.
Highlights of the PRU Study
- Average annual gold production in line with the 2019 Feasibility Study.
- Project within the bottom end of the lowest quartile of the global cost curve, with an average life of mine (“LOM”) all-in sustaining costs (“AISC”) sub $675/oz (net of credits).
- Average annual free cash flow of approximately $85 million per year over the LOM.
- After-tax internal rate of return (“IRR”) of approximately 30%.
- Net present value using a discount rate of 5% (“NPV”) expected to exceed $300 million after-tax.
- Initial capital of approximately $225 million* (including preproduction revenue) with an after-tax payback period of under 3 years.
- Approximately 1Moz of gold and 3Moz of silver recovered.
*Capital cost is inclusive of contingency and pre-production revenue net of taxes but exclusive of early works activities. Value added tax was excluded as it is refundable.
Darren Klinck, President, commented, “The additional engineering work confirms that Cerro Blanco would be a low-cost producer with first quartile AISC as demonstrated in the FS. The gold environment has since improved significantly, and offsets increases to capex due to advancing engineering and de-risking of the Project. Looking forward into 2021, we intend to update the Cerro Blanco resource estimate and mine plan in the first half of the year.”
Significant advancements were made during 2020 with the Project Finance negotiations which included the completion of independent technical engineering, environmental, and social reports along with advancements to long-form term sheets. Further corporate and project finance updates will be provided in Q1. As of January 1, 2021, Bluestone had a cash balance of approximately $50 million.
Further to the resource update in 2019, an additional 15,171 meters of infill drilling were completed in 2020 which focused on the South Zone with the goal to improve the definition of key veins in parallel to expanding the mineralization of known veins outside of the current resource envelope. Recently reported
results included the highest-grade intercept ever drilled at the Project, grading 1,380 g/t gold and 2,194 g/t silver over 1.2 meters (see press Release November 19, 2020). The 2020 infill drill program was successfully completed; however, assay results have been delayed due to slower processing times because of the COVID-19 pandemic. Results from approximately half of the program are still outstanding but once received, the resource estimate and mine plan will be updated.
A draft LOM plan was updated at the end of 2020 and it is anticipated that further optimizations will be captured following the updated resource estimate over the next few months. The average annual production is expected to be in line with the FS over the LOM. A self-perform vs contractor mining trade- off study was undertaken and the self-perform mine development option was deemed to be the best option. This is a change in the execution strategy compared to the FS in addition to the purchase of the mobile mining fleet now being capitalized.
Since the FS, Bluestone has undertaken additional metallurgical test work which has confirmed the flow sheet and resulted in some simplifications of the process plant design. These optimizations include changing the comminution circuit from three-stage crushing, two ball mill configurations to single stage crushing followed by SAG and ball mill configuration.

Non-IFRS Financial Performance Measures
The Company has included certain non-International Financial Reporting Standards (“IFRS”) measures in this news release. The Company believes that these measures, in addition to measures prepared in accordance with IFRS, provide investors an improved ability to evaluate the underlying performance of the Company and to compare it to information reported by other companies. The non-IFRS measures are intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. These measures do not have any standardized meaning prescribed under IFRS, and therefore may not be comparable to similar measures presented by other issuers.
All-in sustaining costs
The Company believes that all-in sustaining costs (“AISC”) more fully defines the total costs associated with producing gold.
The Company calculates AISC as the sum of refining costs, third party royalties, site operating costs, sustaining capital costs, and closure capital costs all divided by the gold ounces sold to arrive at a per ounce amount. Other companies may calculate this measure differently as a result of differences in underlying principles and policies applied. Differences may also arise due to a different definition of sustaining versus non-sustaining capital.
AISC and costs are calculated based on the definitions published by the World Gold Council (“WGC”) (a market development organization for the gold industry comprised of and funded by 18 gold mining companies from around the world). The WGC is not a regulatory organization.
