Condor selects Hanlon Engineering as the Lead Engineer for a Feasibility Study Design for a New Processing Plant Utilizing the Recently Acquired New SAG Mill
Condor Gold (AIM: CNR; TSX: COG) is pleased to announce it has selected Hanlon Engineering & Associates of Tucson, Arizona (“Hanlon”), a wholly owned subsidiary company of GR Engineering Services Limited (GRES) https://www.gres.com.au (ASX:GNG) as the Lead Engineer to develop a Feasibility Study (FS) level of design for a new processing plant around Condor’s recently acquired new SAG Mill at La India Project, Nicaragua. Hanlon will be responsible for the engineering designs, the capital cost and operating costs of the processing plant to a FS level of design.
· Hanlon and GRES are respected and experienced independent Engineering Consultancy Groups, with a recognised capability in the design and construction of Gold Plants within Australasia and South American context.
· The Feasibility Study design will develop costs to a + / – 15% level of accuracy for the design, capex and opex of a fully engineered Processing Plant package, which is normally a mandatory requirement of debt financing.
· The processing plant design will incorporate the SAG mill recently acquired by Condor.
· The processing plant will be designed to a nominal capacity of 2300 tpd, but have the built- in capacity in several key areas to potentially upgrade throughput to 2,850 tpd.
· Hanlon is due to deliver the FS level engineering designs for a new processing plant within 12 weeks.
· Initial production is expected to range from 80,000 to 100,000 oz gold per annum based on the nominal capacity of 2300 tpd.
· Hanlon will be working in conjunction with its parent company GRES utilising their extensive global experience with the design, construction and expansion of gold processing plants
Mark Child, Chairman and CEO commented:
“I am delighted to appoint Hanlon Engineering & Associates to complete the Feasibility Study level design for a new processing plant at La India Project . It’s important to note that Hanlon Engineering was engaged by First Majestic Silver, the vendor of the SAG Mill, to help design the new SAG Mill recently purchased by Condor. Their knowledge of the SAG Mill and involvement with many similar process plant designs completed to date will help fast track the delivery of the Feasibility Study design. A senior engineer from Hanlon is due on site this week. The Feasibility Level designs for the processing plant are due to be delivered to Condor within 12 weeks.”
In recent years, Condor adopted a strategy of de-risking the La India Project focusing on the grant of the master permit to construct and operate a mine by the Ministry of the Environment and Natural Resources, the acquisition of the land needed for the operation of the La India mine, along with continued exploration and permitting of the satellite deposits adjacent to the permitted mine.
With the acquisition of the new Semi-Autogenous Grinding ( SAG) mill package from First Majestic Silver in March 2021, and a series of internal and external strategic analysis, Condor sized the plant by committing to a nominal plant capacity of 2,300 tonnes per day with the potential of expansion to 2,850 tonnes per day or more. This has triggered a requirement for a more robust assessment of the capital and operating costs consistent with that capacity to a FS level of accuracy.
An FS level of accuracy, generally plus-or-minus 15%, requires a more detailed design conducted by an experienced processing plant engineering firm, in conjunction with the development of similar levels of accuracy for all of the constituent inputs needed for a comprehensive financial assessment of the project.
Following extensive internal discussion, Condor selected Hanlon to be the FS design engineer for the processing plant. Hanlons’ team demonstrated an extensive catalog of gold plants in South America and Australasia through its parent company GRES. Together, the Hanlon/GRES group can demonstrate over fifteen gold plants designed and built over the last 20 years. Furthermore, GRES was the design engineer for First Majestic Silver’s San Dimas silver/gold plant expansion, was awarded an Engineering Procurement Construction and Management contract at San Dimas and is therefore familiar with the details of the Metso/Outotec SAG mill Condor recently acquired. Lastly, Hanlon was able to demonstrate existing contacts within the region for construction contractors with current experience with the costs of construction for the area.
About Condor Gold plc:
Condor Gold plc was admitted to AIM in May 2006 and dual listed on the TSX in January 2018. The Company is a gold exploration and development company with a focus on Nicaragua.
In August 2018, the Company announced that the Ministry of the Environment in Nicaragua had granted the Environmental Permit (“EP”) for the development, construction and operation of a processing plant with capacity to process up to 2,800 tonnes per day at its wholly-owned La India gold project (“La India Project”). The EP is considered the master permit for mining operations in Nicaragua. Condor Gold published a Pre-Feasibility Study (“PFS”) on the project in December 2014, summarised in the Technical Report, as defined below. The PFS details an open pit gold Mineral Reserve in the Probable category of 6.9 Mt at 3.0 g/t gold for 675,000 oz gold, producing 80,000 oz gold per annum for 7 years. La India Project contains a Mineral Resource of 9,850 Kt at 3.6 g/t gold for 1.14 Moz gold in the Indicated category and 8,479 Kt at 4.3 g/t gold for 1.18 Moz gold in the Inferred category. The Indicated Mineral Resource is inclusive of the Mineral Reserve. A gold price of $1,500/oz and a cut-off grade of 0.5 g/t and 2.0 g/t gold were assumed for open pit and underground resources, respectively. A cut-off grade of 1.5 g/t gold was furthermore applied within a part of the Inferred Resource. Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. There is no certainty that any part of the Mineral Resources will be converted to Mineral Reserves.
Environmental Permits were granted in April and May 2020 for the Mestiza and America open pits respectively, both located close to La India. The Mestiza open pit hosts 92 Kt at a grade of 12.1 g/t gold (36,000 oz contained gold) in the Indicated Mineral Resource category and 341 Kt at a grade of 7.7 g/t gold (85,000 oz contained gold) in the Inferred Mineral Resource category. The America open pit hosts 114 Kt at a grade of 8.1 g/t gold (30,000 oz) in the Indicated Mineral Resource category and 677 Kt at a grade of 3.1 g/t gold (67,000 oz) in the Inferred Mineral Resource category. Following the permitting of the Mestiza and America open pits, together with the La India open pit Condor has 1.12 Moz gold open pit Mineral Resources permitted for extraction, inclusive of a Mineral Reserve of 6.9 Mt at 3.0 g/t gold for 675,000 oz gold.
