Contact: Web: www.miningamerica.org. has committed to spending a minimum of $4 million and to completing a mini- mum of 3,000 m of drilling over an initial 18-month period. Newcrest will operate the exploration program. Newcrest and Mirasol are working to advance the Gorbea drill permitting pro- cess and to upgrade the exploration camp ahead of a planned first-quarter 2019 restart of the exploration program, which will initially focus on the Atlas project. The scale of the Atlas gold-silver sys- tem, combined with the relatively modest amount of exploration drilling to date and the range of priority targets, highlights the project as a large, under-explored system, requiring further drill testing to identify potential large-tonnage, bulk-minable, gold-silver mineralization. Reunion and Barrick have formed a 50:50 alliance to jointly explore, develop, and mine certain mineral projects in the Guiana Shield, including in Guyana, Suri- name, French Guiana, and the north and northeast regions of Brazil. Concurrently, Barrick has increased its interest in Re- union to 19.9% through participation in Reunion's previously announced private placement offering. Reunion will initially contribute the Waiamu, Aremu, Arawini, and Oko pro- jects, all in Guyana. Barrick will initially fund $4.2 million for these projects as credit for historical exploration expendi- tures by Reunion, with subsequent fund- ing to be on a 50:50 basis between the companies. Barrick can at any time designate an included project as a "designated pro- ject." Following such designation, Barrick will sole fund the project until completion of a feasibility study. Upon completion of a feasibility study, Barrick's interest in the project will increase to 70%, and Re- union will retain a 30% interest. If Bar- rick does not deliver a feasibility study, the project returns to the alliance as an included project. Reunion will manage all exploration projects within the alliance until such pro- jects are defined as designated projects. Barrick will manage all designated projects. Limited Production Resumes at Cobre Las Cruses in Spain First Quantum Minerals reported that the hydrometallurgical plant at Cobre Las Cruces has resumed copper production, processing lower-grade stockpiled ore. The stockpiled ore is expected to provide feed for the next several months while the company obtains the necessary regulatory approvals to begin mining at Phase 6, an area unaffected by a recent landslide at the mine, the company said. A landslide at the mine, located in Gerena, Spain, forced the closure of the open-pit operation and management de- cided to shut down the hydrometallurgical complex. Prior to the incident, mine per- sonnel identified a risk and immediately implemented safety protocols. The pit was evacuated and no injuries occurred. The slide mainly affected the north slope of the mine pit and part of the mine waste storage area. Materials, mostly clay, slid into the pit and covered the majority of the pit floor, but did not impact the area containing Phase 6 or access to that area. An investigation into the causes of the slide and its impact continues, the company said, and it is working with government authorities and independent geotechnical experts. Meanwhile, work to restore the pit continues. While the investigation is being com- pleted, work to restore the pit continues. Normal mining activities will resume once regulatory approvals have been received. Phase 6 contains the majority of the re- source remaining in the current ore body.
