The study was completed by Kilborn Limited and contemplated production of 325 koz Ag per annum for 7 years. The historic Gowanda tailings contain historic mineral resources of 2.96 Moz Ag, which together with the company’s flagship high-grade Castle East 43-101 compliant resource (of 7.56 Moz Ag @ 8,582 g/t Ag + Cu-Ni-Zn-Co-Pb credits) grows company mineral resources by +42% to 10.6 Moz AgEq (0.17 Moz AuEq) - 99% from silver. The historic feasibility study reported an NPV15% of C$0.767m at silver price US$8/oz from capex of C$4.7m - which increases to an NPV15% of US$20m at our estimated 3-month trailing average silver price of US$79/oz according to the NPV sensitivity provided in the study. NTH stock gained by 1c/sh on this news to 24c/sh, before closing the week (ending 15 May) down -4.3% (just underperforming silver developer median weekly drop of -2.2%) to 22c/sh, market cap C$29m, market cap/oz resource US$1.97/oz AgEq ($121/oz AuEq) - in-line with silver developer group median US$1.97/oz AgEq and a 56% discount to group mean US$4.48/oz AgEq ($275/oz AuEq).
