Araguaia Nickel North hosts the Vale do Sonhos deposit. The deposits will be mined by conven- tional open-pit truck-and-shovel techniques using contractors. No blasting will be nec- essary. Reverse circulation grade-control drilling will be completed at a 10-m x 10-m spacing well ahead of mining. This combined with the use of visual control of the limonite and transition boundary, face sampling, stockpile sampling, and ore feed sampling, supports a comprehensive mine- to-mill strategy that is designed to maintain consistent feed to the process plant. The annual mining rate peaks at 3.5 million mt/y between production years two and seven before dropping down to 3 million mt/y for the remainder of the proj- ect life. The mine supplies high nickel grades in the early mine life, reaching 2% in production year two. The nickel grade is above 1.8% for the majority of the first 10 years of production and reduces to av- erage approximately 1.6% nickel for the remaining mine life. Waste will be stored in external dumps near the pits. Ore will be transported to stockpile hubs near each deposit. Depend- ing on plant demand, ore will be hauled from hub stockpiles or directly from the pits to run-of-mine stockpiles at the plant.

Initial capital ex- penditures to develop the project are esti- mated at $254 million. Life-of-mine cash costs are estimated at $714/oz, and all-in sustaining costs are estimated at $753/oz. Proven and probable reserves total 1.93 million oz. The feasibility study confirmed the preferred development approach to be a conventional truck-and-shovel, open- pit mining operation, with a mineral processing circuit incorporating pri- mary crushing, grinding, and cyanide leaching, followed by gold recovery using carbon-in-pulp, stripping and electrowinning. The Boto project team is continuing to optimize aspects of project design and complete an infrastructure condemnation drilling program. The exploration team has worked to consolidate additional ex- ploration concessions near the project and is conducting ongoing exploration to expand resources in proximity to the resource pits and identify and evaluate high-priority exploration targets for addi- tional mineral resources. (Regional News-Africa - from p. 27) Premier's 40% owned South Arturo prop- erty in the Carlin Trend, and approximate- ly 10 kilometers northwest from Barrick Gold's Goldstrike operations. Premier will have the option to acquire a 100% interest in the project by making $500,000 payments to Ely Gold over a five-year period and Ely Gold will retain a 2% net smelter royalty. Premier is currently participating in the construction of two new mining op- erations at its South Arturo joint venture that are located within 3 kilometers of Rodeo Creek. Production at South Arturo is anticipated to ramp-up in 2019 and the partnership is drilling multiple tar- gets in an effort to increase reserves and resources. "This acquisition is consistent with Pre- mier's strategy of growing land positions in the heart of prolific gold districts," stated Ewan Downie, president and CEO. "The Ro- deo Creek property has seen little exploration compared to the rest of the Carlin Trend and we are excited to get to work on this project." (News-Leading Developments - from p. 8)
