Diamond Drilling Results from the La Cobota Copper Project, Mexico

TORONTO, ONTARIO--(Marketwired - Feb. 10, 2016) -


Era Resources Inc. ("Era" or the "Company") (TSX:ERX) is pleased to announce the results of the recent initial diamond drilling program at the La Cobota Project ("La Cobota" or the "Project") located in Sonora, Mexico.

The Project comprises three contiguous mining concessions that together encompass approximately 1,800 hectares. The concessions are situated in the mining-friendly jurisdiction of Sonora State, Mexico, and are located on privately held land approximately 80 kilometres east-southeast of the town of Sonoyta and 10 kilometres south of the US border (Figure 1). The project area is easily accessible via existing roads and unsealed ranch tracks. Era is party to an option agreement for the mining concessions and has undertaken the drilling as part of a systematic exploration program to assess the prospectivity of the mining concessions.

During the period from mid-December 2015 to mid-January 2016, Era completed eight diamond drill holes totaling 955.60 metres at La Cobota (Table 1 and Figure 2). All drill holes were HQ size (63.5 milimetres diameter) and core recovery was excellent. The drill program was designed to test the continuity and grade of an outcropping mineralized structure that was the focus of historical underground mining operations. Assay results from the drilling (Table 2) confirm the presence of high grade copper-silver mineralization and suggest that the mineralization occurs within a north-east plunging shoot.

Mineralization at La Cobota is hosted within a complex iron-oxide vein system that transects an equigranular to porphyritic quartz monzonite intrusion. The principal vein (Vein #1, Figure 2) targeted by drilling is heavily oxidized and composed of massive to semi-massive magnetite and hematite. Copper mineralization principally occurs as fine-grained chalcocite, with some native copper and other copper oxides. Minor remnant chalcopyrite and pyrite is also observed. The vein is faulted and brecciated to a variable degree; and is locally intruded by mafic dykes that appear to stope-out the mineralization. Drilling intersected a major fault beneath the historical mine workings that juxtaposes the quartz monzonite against a polymictic meta-conglomerate unit. This fault is interpreted to be a thrust structure that may truncate the mineralized vein at depth.

Under the terms of the option agreement for the La Cobota mining concessions, Era has an exclusive right to conduct exploration and is responsible for all land taxes and annual concession or permit fees during the option period, which ends on July 1, 2016. The Company has the right to acquire 100% of the concessions for a fixed amount of US$275,000, subject to a 2.5% Net Smelter Return royalty interest granted to the vendor of the mineral concessions, once it elects to proceed with the acquisition.

"The assay results from the diamond drilling at La Cobota suggest that the mineralized iron oxide vein has significantly more structural complexity and grade variability than was originally anticipated from surface mapping and the available historical mining records. Work is continuing to assess the viability of the mineralized structure to host a resource and the Company will make a decision on the La Cobota option in due course," said Chief Executive Officer Pieter Britz.

Diamond Drilling Program

A total of eight diamond drill holes were completed at the Project (Figure 2), for a total of 955.60 metres of drilling (Table 1). Seven of these holes (15LC001-006 and 16LC007) were targeted at the main mineralized structure (Vein #1), which was the principal site of historical mining operations. An eighth and final hole was subsequently completed to test a number of mapped veins in the hanging wall to the northwest of Vein #1.

Assay Results

A total of 264 half-core samples were collected from the drill core using a diamond blade saw. Samples were transported to the Bureau Veritas ("BV") sample preparation laboratory in Caborca, Mexico. Gold fire assays were subsequently completed at the BV analytical laboratory in Hermosillo, Mexico. A multi-element assay suite was analyzed at the BV analytical laboratory in Vancouver, Canada.

A quality assurance/quality control ("QA/QC") procedure adopted by the Company confirms that assay results are reliable. This procedure included routine analysis of blank samples and certified standard reference materials. In addition, BV implemented an internal QA/QC procedure consisting of blanks, duplicates, repeats and standard reference materials.

Significant mineralized intersections from the diamond drilling are shown in Table 2. Intersections have been calculated using a 0.1% Cu cut-off, including a maximum of 1 metre of internal dilution. Higher grade zones have been calculated using a 0.5% Cu cut-off, including a maximum of 1 metre of internal dilution.

Full drill results will be available on the Company's website.
