Primero Mining Corp. Reports Year-End 2017 Mineral Reserves and Resources

20.03.2018 | 12:05 Uhr | GlobeNewswire
TORONTO, March 20, 2018 - Primero Mining Corp.(“Primero” or the “Company”) (TSX:P) today announced its updated year-end 2017 Mineral Reserves and Mineral Resources.

Primero commenced a strategic review process in early 2017 that resulted in the sale of the Black Fox Complex in October 2017 and the sale of the Cerro del Gallo development project in November 2017. In January 2018 the Company also announced that it had entered into the Arrangement Agreement whereby First Majestic will acquire all of the issued and outstanding common shares of Primero. The transaction is expected to close in or around April 2018, subject to applicable regulatory approvals and the satisfaction of other customary conditions.

Primero’s Mineral Reserves and Mineral Resources as at December 31, 2017 include the San Dimas mine and adjacent Ventanas exploration property in Durango, Mexico.

Total Proven and Probable Mineral Reserves at December 31, 2017 were 495,000 ounces of contained gold and 39.7 million ounces of contained silver. Total Measured and Indicated Mineral Resources at year-end 2017 were 823,000 ounces of contained gold and 62.2 million ounces of contained silver. Total Inferred Mineral Resources at December 31, 2017 were 799,000 ounces of contained gold and 73.9 million ounces of contained silver.

The year-end 2017 Mineral Resource and Mineral Reserve estimates were completed internally with applied metal prices of $1,200 per ounce of gold and $17.00 per ounce of silver, and foreign exchange rates of 18.00 Mexican pesos per US dollar. The San Dimas Mineral Resources are calculated inclusive of Mineral Reserves.

San Dimas

San Dimas Proven and Probable Mineral Reserves at December 31, 2017 totalled 4.1 million tonnes grading 3.8 grams per tonne (“g/t”) gold and 304 g/t silver with 495,000 ounces of contained gold and 39.7 million ounces of contained silver. This represents a decrease of 22,000 ounces of gold and 1.5 million ounces of silver from year-end 2016. The decrease is primarily attributable to 2017 mining depletion, materially offset by successful drilling results.

The Company has applied a two-pass cut-off grade at San Dimas. Firstly, an all-in sustaining cost cut-off grade was applied to highlight areas for inclusion in the Mineral Reserve, followed by the application of an operating cost cut-off grade to highlight additional incremental material for potential inclusion. The all-in sustaining cost cut-off grade applied was unchanged from 2016, at 3.22 g/t gold equivalent (“AuEq”) and considers direct operating costs and sustaining capital costs. The operating cut-off grade next applied was also unchanged from 2016, at 2.22 g/t AuEq and considers direct operating costs only.

San Dimas Measured and Indicated Mineral Resources at December 31, 2017 totalled 4.9 million tonnes grading 5.1 g/t gold and 385 g/t silver with 811,000 ounces of gold and 60.9 million ounces of silver contained, inclusive of Mineral Reserves. Inferred Resources totalled 6.9 million tonnes grading 3.5 g/t gold and 319 g/t silver with 782,000 ounces of gold and 70.9 million ounces of silver contained.

Quality Control

San Dimas drilling and sampling was conducted by Primero's exploration team. All drill-hole samples at San Dimas and Lechuguilla are 1/2 core and analyses reported herein were performed in the ISO certified independent laboratory SGS Servicios Minerales in Durango Mexico, using fire assay with atomic absorption finish or gravimetric finish for values over 10 g/t gold. Intercepts cited represent true widths and drilling is generally intersecting interpreted mineralized zones at a high angle. Primero's quality control program includes systematic insertion of blanks, standard reference material and 5% of rejects are re-assayed to ensure laboratory accuracy. Generally, in a block of twenty samples one will be a standard and one will be a blank.

The mineral reserve estimates in this news release have been prepared in accordance with NI 43-101 and the Canadian Institute of Mining, Metallurgy and Petroleum classification systems, as required by Canadian securities regulatory authorities. These standards differ significantly from the requirements of the United States Securities and Exchange Commission (the “SEC”), and reserve and resource estimates disclosed in this news release may not be comparable to similar information disclosed by U.S. companies. For United States reporting purposes, SEC Industry Guide 7 under the United States Securities Exchange Act of 1934, as amended, as interpreted by Staff of the SEC, applies different standards in order to classify mineralization as a reserve. As a result, the definition of “proven and probable reserves” used in NI 43-101 differs from the definition in the SEC Industry Guide 7. Under SEC standards, mineralization may not be classified as a “reserve” unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made. Among other things, all necessary permits would be required to be in hand or issuance imminent in order to classify mineralized material as reserves under the SEC standards. Accordingly, mineral reserve estimates contained in this news release may not qualify as “reserves” under SEC standards.

In addition, this news release uses the terms “measured and indicated resources” and “inferred resources” to comply with the reporting standards in Canada. The Company advises United States investors that while those terms are recognized and required by Canadian regulations, the SEC does not recognize them. United States investors are cautioned not to assume that any part or all of the mineral deposits in these categories will ever be converted into mineral reserves. Further, “inferred resources” have a great amount of uncertainty as to their existence and as to whether they can be mined legally or economically. Therefore, United States investors are also cautioned not to assume that all or any part of the “inferred resources” exist. In accordance with Canadian securities laws, estimates of “inferred resources” cannot form the basis of feasibility or other economic studies. It cannot be assumed that all or any part of “measured and indicated resources” or “inferred resources” will ever be upgraded to a higher category or are economically or legally mineable. In addition, disclosure of “contained ounces” is permitted disclosure under Canadian securities laws; however, the SEC only permits issuers to report mineralization as in place tonnage and grade without reference to unit measures.

NI 43-101 also permits the inclusion of disclosure regarding the potential quantity and grade, expressed as ranges, of a target for further exploration provided that the disclosure (i) states with equal prominence that the potential quantity and grade is conceptual in nature, that there has been insufficient exploration to define a mineral resource and that it is uncertain if further exploration will result in the target being delineated as a mineral resources, and (ii) states the basis on which the disclosed potential quantity and grade has been determined. Disclosure regarding exploration potential has been included in this news release. United States investors are cautioned that disclosure of such exploration potential is conceptual in nature by definition and there is no assurance that exploration will result in any category of NI 43-101 mineral resources being identified.
