Komatsu America Corp. announced plans to move company headquarters to Chicago in 2020. The new site at Triangle Plaza, 8770 W. Bryn Mawr Ave., will feature a new, open floor plan designed to reinforce the company’s focus on cross-discipline collaboration that drives customer-first solutions and services.

General Moly Inc. reported March 1 that it has identified a potential high-grade, copper-silver exploration target along with a significant zinc mineralized area at the Mt. Hope Project site, southeast of the Mt. Hope’s molybdenum deposit in central Nevada. Because of the copper-silver target and zinc mineralization, General Moly undertook a high-intensity, ground-based induced polarization survey to determine if potential continuity and the size of the mineralization would justify additional exploration and evaluation. The IP survey was completed in February 2018 by Quantec Geoscience and indicates a fairly continuous group of high chargeability anomalies that appear aligned with the recently identified copper-silver target. Recent mine development milestones marked by Nevada Copper Corp. position the company to restart construction of the Pumpkin Hollow underground copper project. Nevada Copper Corp. announced May 10 that it signed a preworks contract with Cementation USA Inc. The mining contractor, which worked on the project in 2013, will prepare an existing shaft and hoist for the restart of underground construction. The shaft is approximately 1,900 feet and is 250 feet from completion. The company also has secured long-lead items — including components for a process plant and mobile and underground mining equipment — and is transitioning from care and maintenance to active status.

Torq Resources Inc. acquired the Speedway Gold Project in western Utah, near the Nevada border. The Speedway property is approximately 2,668 acres of prospective terrain that hosts a large gold-in-bedrock anomaly. This leads Torq’s technical team to believe that the underexplored area represents an early-stage, Carlin-style gold target. The company paid $25,000 upon signing and will be required to pay steadily escalating annual lease payments as well as the underlying claim fees. There is no required work commitment and the lease agreement can be terminated at any time after one year. The lease agreement may be bought out at any time for $1 million, subject to a buyable 2 percent royalty to the underlying owner.

Trifecta Gold Ltd. optioned the Yuge Property, a high-grade gold prospect in northern Nevada, from Silver Range Resources Ltd., the company announced Feb. 28. The Humboldt County property covers the Columbia and Juanita mines, which produced on a small scale between 1870 and 1937. The most recent reported production was 2,350 tons of oxide ore in 1936-37 from the Columbia Mine. Trifecta Gold and Silver Range Resources commenced exploration work in April.

American Pacific Mining Corp. expanded Tuscarora Gold by staking an additional 67 claims in Elko County, the company announced March 19. The 24-claim, 447-acre project, about 13 miles from the Jerritt Canyon deposit, increased in size to 91 claims and 1,818 acres. Tuscarora consists of two previously tested, high-grade gold drill targets, the South Navajo and the East Pediment zones. The company launched a drill program that includes an initial 7,500 feet of drilling, or approximately 10-12 holes. Results will be evaluated and then a second stage of drilling will complete the approximate 19-hole program.

Haver & Boecker, an equipment manufacturer and solutions provider for aggregates and mining applications, announced that it offers the Tyler L-Class vibrating screen for classifying wet or dry material and dewatering method. Producers can customize the 6-foot-wide machine in two lengths, 16 and 20 feet length. Primarily mounted horizontally, the L-Class can also be inclined or declined as much as 3 degrees. The linear L-Class handles up to 400 tons per hour and features a 45-degree mounted double-shaft overhead drive system with direct-mounted motors.

Epiroc introduced specialized tunneling tools, the SB 302 and SB 452 Tunnel versions of the Solid Body breaker range. The modifications aim to extend equipment life and reduce operating costs in underground applications. The special tunneling tool with a collar supporting a robust front shield and dust cover minimizes the dust intake when working on overhead areas. Two restrictors are available which enable the performance of the hydraulic breaker to be adjusted for either traditional scaling operations or for more challenging rock breaking jobs.

Epiroc released automation features for the Scooptram underground loader in May. The Scooptram Automation Regular package allows the Scooptram to be controlled through an operator station from a remote location. An operator can control the loader while out of sight or transition from manual to automatic mode. The company states that the package, which includes cameras, sensors, safety modules and a safety system, allows customers to automate a single loader without much expense or extensive infrastructure alternations.

Aiming to kick off the first primary vanadium mine in North America, Prophecy Development Corp. submitted a plan of operations for the Gibellini vanadium project in Eureka County to the Bureau of Land Management. The submitted plan, announced May 9, was prepared by SRK Consulting (U.S.) Inc. with more than 1,100 pages of detailed development plans for an open pit mine and processing facilities. The Gibellini Project is expected to produce an average of 15.7 million tons of ore containing 120.5 million pounds of vanadium over a seven-year mine life. The company hopes to acquire permitting by 2020.
