EXPLORATION – Juanicipio Project
The Valdecañas Vein System is a multi-stage, high-grade vein swarm comprising the Valdecañas vein, characterized by large dilatant zones (bulges) in its east and western reaches, the hangingwall Anticipada Vein, the Pre-Anticipada Vein, several en echelon splays and a series of subparallel northeast-trending cross veins that comprise the Venadas-Valentina Vein family. The recent discovery of these northeast-trending veins close to the planned production areas, coupled with the expanding high-grade Anticipada and Pre-Anticipada veins, should add significantly to the growing mineral endowment of the project and, importantly, provide considerable mining flexibility throughout an extended mine life. Deep mineralization on the Valdecañas Veins remains open laterally for several hundred metres to the claim boundaries on both ends; to the east claim boundary for Anticipada; and Pre-Anticipada and to depth across all veins.
Exploration drilling at Juanicipio resumed in May of 2020 after a temporary COVID-19 halt imposed by the Mexican Government (see COVID-19 Juanicipio Project above). Since then, full drilling has resumed with five rigs, including three dedicated to Devico directional drilling. Drilling is currently focused on continued step-out and infill drilling of the Valdecañas Deep Zone. Holes are also being directed at the Anticipada Vein and NE-trending Venadas Vein family targeting them independently from the Valdecañas Vein. Despite the temporary COVID-19 restrictions noted above, the full Juanicipio 2020 drilling program is expected to be completed as planned in 2020.
MAG’s principal focus is the successful development of the Juanicipio Project and to further explore the Juanicipio property. The Company continually looks to enhance its project portfolio by evaluating new projects and through successful exploration of its current property holdings. However, MAG continues to execute its business plan prudently, with on-going project evaluations focusing primarily on potential high-grade, high-margin, district-scale opportunities.
Under the terms of an EPCM agreement, Fresnillo and its affiliates are overseeing the construction of the 4,000 tpd process plant and associated surface and underground infrastructure. In the previous quarter, surface construction progress at Juanicipio was limited due to COVID-19 restrictions as noted above. Construction ramped up again starting June 1, 2020 and into the quarter ended September 30, 2020, and according to Fresnillo, the overall development timetable currently remains unchanged with the Juanicipio processing plant expected to be commissioned in mid-2021.
In the nine months ended September 30, 2020, further development progress was made on construction of the flotation plant and other infrastructure. The mill foundations are completed and curing. Underground development to date at Juanicipio is now at 32 km (20 miles) with access to the upper portion of the resource now achieved. Initial development indicates that the grade and width of the vein are in line with previous drilling-derived estimates, and preparation of the first production stope was concluded during the three months ended September 30, 2020.
Initial production from the mine commenced during the third quarter ahead of the original schedule, with 42,476 tonnes of mineralized development material successfully processed through the Fresnillo plant in August and September of 2020 (see Initial Mine Production above). The Joint Venture produced and sold 394 thousand silver ounces, 610 gold ounces, 138 tonnes of lead and 174 tonnes of zinc in the third quarter. Provisional sales net of related costs, totaling $7,995 on a 100% basis, was credited against the Juanicipio capitalized costs, in accordance with the Company’s pre-commercial production accounting policy.
Mineralized material from the mine is expected to be processed at a rate of 16,000 tonnes per month at the Fresnillo plant facility (100% owned by Fresnillo) until the Juanicipio plant is commissioned in mid-2021. Subsequent to the quarter end, a further 15,400 tonnes were processed in October 2020. The Juanicipio plant is expected to reach 85% of its 4,000 tpd nameplate capacity by Q4-2021. An Operator Services agreement has been finalized which will become effective upon initiation of commercial production. As well, both lead and zinc concentrate off-take agreements have been executed by Minera Juanicipio with Met-Mex Peñoles, S.A. De C.V., under which both concentrates will be treated at benchmark market terms in Torreón, Mexico.
Although all activities have resumed at Juanicipio, the COVID-19 impacts could result in additional medical and other costs, project delays, cost overruns, and operational restart costs. The total amount that the Company is required to finance in order to maintain its proportionate ownership in the project may increase from these and other consequences of the COVID-19 outbreak. See “Virus outbreaks may create instability in work markets and may affect the Company’s Business” in “Risk and Uncertainties” below.
According to Fresnillo, the Juanicipio development is expected to create approximately 2,750 jobs during construction and 1,720 jobs once at full production, with potential to scale-up operations in the future beyond 4,000 tpd.
On the exploration front, most of the Juanicipio property remains unexplored with many untested exploration targets still to be pursued by the joint venture partners. Exploration drilling in recent years has been primarily designed to both convert the Inferred Mineral Resources included in the Deep Zone into Indicated Mineral Resources, and to further trace the Deep Zone laterally and to depth.
After a temporary halt in exploration activity in the prior quarter due to COVID-19 restrictions, (see COVID-19 Juanicipio Project above), drilling on the property resumed in the third quarter with five rigs currently on site. Drilling is presently focused on continued step-out and infill drilling of the Valdecañas Deep Zone. Holes are also being directed at the Anticipada Vein and NE-trending Venadas Vein family targeting them independently from the Valdecañas Vein. With the temporary COVID-19 restrictions noted above lifted, the full Juanicipio 2020 drilling program is expected to be completed as planned in 2020.
With drill roads completed and drill pads fully permitted, a 6,500-metre Phase I surface drilling program commenced subsequent to the quarter end in November 2020. MAG’s Phase I drilling priorities include: determining the depth to the thick section of high-potential limestone host formations known regionally to lie just below the comparatively unfavorable host rocks of the Deer Trail mine; tracing the identified steeply-dipping feeder structures to depth into these limestones; and, locating massive sulfide mineralization controlled by the above.
EXPLORATION – Deer Trail Project
In late 2018, the Company entered into an option agreement with another private group whereby MAG has the right to earn 100% ownership interest in a company which owns the Deer Trail project in Utah. MAG paid $150 upon signing the agreement and another $150 subsequent to September 30, 2020. To earn 100% interest in the property, MAG must make remaining cash payments of $1,700 over the next 8 years and fund a cumulative of $30,000 of eligible exploration expenditures ($3,495 incurred to September 30, 2020) by 2028. Upon MAG’s 100% earn-in, the vendors would retain a 2% NSR.
