(BVL: VOLCAACI / VOLCABC1; BCS: VCMAC1 / VCMBC1; LATIBEX: XVOLB) is pleased to announce results from its diamond drilling program at the Islay Mine, Chungar Unit, located in the Department of Pasco, 214 Km from the city of Lima. To date, 16,043 meters of diamond drilling were completed with the purpose of exploring and defining the size of the economic mineralization of Veta Sur and associated splits. The results are satisfactory, allowing for a considerable increase of inferred resources at the Islay Mine in silver tonnage and grade. Highlights of the Drilling Program: DDH-U-CH-15-031: 1.61 m @ 0.22% Cu, 0.92% Pb, 3.14% Zn & 15.77 oz/t Ag DDH-U-CH-15-038: 3.45 m @ 0.05% Cu, 1.08% Pb, 1.51% Zn & 13.94 oz/t Ag DDH-U-CH-15-039: 4.04 m @ 0.08% Cu, 1.55% Pb, 3.03% Zn & 16.37 oz/t Ag DDH-U-CH-15-056: 3.78 m @ 0.05% Cu, 0.50% Pb, 0.93% Zn & 15.46 oz/t Ag DDH-U-CH-15-057: 2.57 m @ 0.16% Cu, 2.58% Pb, 6.08% Zn & 30.29 oz/t Ag DDH-U-CH-15-085: 1.05 m @ 0.13% Cu, 0.58% Pb, 1.08% Zn & 28.15 oz/t Ag The assay results from the fifty nine diamond-drill holes are summarized in Exhibit No.1. A longitudinal section of Veta Sur, detailing the location and grades of the perforations executed is displayed below as Exhibit No.2. “The diamond drilling program developed at Veta Sur discovered a new mineralized structure at the Islay Mine with excellent grades and silver mineralization associated with polymetallic mineralization, recognizing to date one ore shoot 700 meters in length and 300 meters deep. Moreover, it should be noted that the mineralized system continues open in a northwest-southeast direction, principally at depth. This important discovery allowed for a 49% increase of silver grade content of inferred resources as of June 2015 compared to those of December 2014", said Jorge Chavez, Corporate Manager of Geology & Brownfields. Quality Assurance & Quality Control (QA-QC) Following detailed geological and geotechnical logging, drill-core samples are split at the site. Half of the core is submitted to the mine´s laboratory for the corresponding chemical analysis. The remaining half of the core is retained at site for verification and reference purposes. Following physical preparation, samples are assayed for base metals and silver by atomic absorption methods utilizing aqua regia digestion. The QA-QC program includes the blind insertion of certified reference standards, assay blanks, field duplicates (twin samples), duplicate rejections and duplicate pulps; at a frequency of approximately 1 per 20 normal samples. 1 CORPORATE OFFICE TICKER SYMBOLS Av.

Volcan Compañía Minera S.A.A. Volcan Compañia Minera is a polymetallic mining Company and one of the largest producers of zinc, lead and silver in the world. The Company is considered one of the lowest cost producers in the industry due to the quality of its ore deposits. Volcan began operations in 1943 at the heights of the Ticlio Pass. All operations are located in the central mountains of the Peruvian Andes and include the operating units, Yauli, Chungar, Alpamarca and Cerro de Pasco. These four operating units include a total of 12 mines, seven concentrator plants and one oxide leaching plant. The Company is growing organically through expansion of its plants and from exploration and development of its own portfolio of brownfield and greenfield projects. At the same time, the Company continuously searches for accretive opportunities in the region.
