Pulacayo 1 000 t/d Phase I Feasibility Study - NI 43-101 Technical Report 090644-3-0000-20-IFI-100 The Run-of-Mine (ROM) will be trucked out of the mine and tipped at the stockpile at the process plant. The average grades of the RoM product delivered to the plant have been estimated to be 240 g/t for silver, 1.10% for lead and 1.92% for zinc over the life of mine. From the stockpile, the ROM material will pass through a beneficiation plant comprising a crushing circuit, a milling and cycloning circuit, two sequential floatation stages (the first for lead and the second for zinc) and a filtration plant, producing a lead concentrate and a zinc concentrate. The contents and grade of each concentrate are tabulated below: Table 22.2: Products of the Process Plant Lead Concentrate Zinc Concentrate Pb (%) 48 1.12 Zn (%) 6.53 51 Ag (g/t) 7.438 411 Fe (%) - 2.19 Si (%) - 1.93 As (%) 1.48 0.03 Sb (%) 1.25 0.04 Bi (%) 0.03 - The two concentrates will then pass through the sales process. The quantities of concentrate and the cost per equivalent silver ounce over the mine life are shown in the table below: TWP Sudamérica S.A. Av.

Economic calculations used the following factors: lead equivalent ounces is Lead AgEq. = (Lead Tonnes x 2204lbs/t x $0.86/lb) / $28/oz and for zinc equivalent ounces is Zinc AgEq.= (Zinc Tonnes x 2204lbs/t x $1.00/lb) / $28/oz TWP Sudamérica S.A.
