Tuvatu Gold Project

Overview

The Tuvatu Gold Project is located 17 km from the Nadi International Airport on the main island of Viti Levu in Fiji. Discovered in 1987, Tuvatu is a high grade, low sulphidation, epithermal gold deposit hosted inside a South Pacific style volcanic caldera. The deposit occurs along the Viti Levu lineament, Fiji’s own corridor of high grade gold deposits. Tuvatu is situated upon a 5 hectare footprint inside a larger 384 hectare mining lease. The project contains numerous high grade prospects proximal to Tuvatu, at depth, and up to 1.50 km along strike from the resource area, giving near-term production potential and further discovery upside inside of one of Fiji’s underexplored volcanic goldfields.

Tuvatu was advanced by previous owners through underground exploration and development from 1997 through to the completion of a feasibility study in 2000. Acquired by Lion One in 2011, the project has over 100,000 meters of drilling completed to date in addition to 1,600 meters of underground development.

In January 2016 the Hon. Prime Minister of Fiji, Mr. V. Bainimarama, formally presented the previously granted Tuvatu Mining Lease to Lion One. This concluded the permitting process for the development of an underground gold mine and processing plant at Tuvatu, demonstrating strong government support for Fiji’s 85 year-old gold mining industry.

As per its independent June 1, 2015 NI 43-101 PEA Technical Report on the Tuvatu Gold Project, the Company envisages a low cost underground gold mining operation producing 352,931 ounces of gold at head grades of 11.30 g/t Au over an initial 7 year mine life. This includes production of 262,000 ounces at 15.30 g/t through to the end of year three.  Estimated cash cost is US$567 per ounce with all-in sustaining cost of US$779 per ounce. Total capex of US$48.6 million includes a contingency of US$6.1 million with an 18 month preproduction schedule and 18 month payback on capital.  At a US$1,200 gold price, the project generates net cash flow of US$112.66 million and an IRR of 52% (after tax).  The Company is not basing its production decision on a feasibility study of mineral reserves demonstrating economic and technical viability; as a result there is increased uncertainty and economic and technical risks associated with its production decision.
