Goldgroup talks exploration results at Cerro Prieto

GOLDGROUP UPDATES EXPLORATION EFFORST AT CERRO PRIETO GOLD MINE

Goldgroup Mining Inc. has provided an update to recently completed surface exploration at its 100-per-cent-owned Cerro Prieto open-pit, heap leach gold mine located in Sonora, Mexico.

Cerro Prieto mine

The Cerro Prieto mine is an open pit heap leach gold mine located in Sonora, Mexico. From the start of mining operations in 2013 to date, Cerro Prieto has produced 117,033 ounces of gold. Continuing mining operations continue to produce approximately 1,000 to 1,200 ounces of gold monthly.

Mined zones and more recently discovered mineralization are located within or near the Cerro Prieto shear, a major north-trending, near-vertical shear zone up to 65 metres in width. The shear zone contains a series of major veins near its margins, along with secondary veins and zones of stringers, breccias and silicification which, with the veins, forms a mineralized system from 15 to 65 metres thick. Recent exploration has resulted in the discovery of significant mineralization in several new zones along the trend of the Cerro Prieto shear, both north and south of the existing mine.

Cerro Prieto exploration

Nueva Esperanza zone drilling

The company has drill tested the Nueva Esperanza zone immediately north and contiguous to the Esperanza zone currently being mined. Seventeen preliminary drill holes tested this zone at a 25-metre line spacing. Significant mineralization was encountered across appreciable widths in nine of the drill holes with assay result as shown in the first attached table.

Reyna zone -- surface trench sampling

The Reyna zone is contiguous to and immediately north of the Nueva Esperanza zone referred to herein. Surface trenching has exposed this zone over 90 metres, and chip sampling assay results returned significant gold values. This zone along with Nueva Esperanza requires additional exploration drilling to determine if contained mineralization will be able to meet minimum tonnage and cut-off grades to allow future mining; however, based upon geology, initial drilling and trenching results achieved to date, along with their location immediately along strike to the north of the Esperanza zone, management is confident these two zones will provide future mine feed.

Recent surface exploration identifies new mineralized zones

Cata, Coati and Cascabel zones

Recent surface exploration up to 1.7 kilometres south of the mine's heap leach pads has identified the potential extension of the Cerro Prieto shear at the Cata and Coati zones, along with the Cascabel zone, a parallel mineralized structure. Chip and grab sample analytical results for these surface samples assayed at the Cerro Prieto mine lab. Note that exploration surface samples from these three zones as well as the Reyna zone referred to, have not been verified by an independent laboratory and the reader is cautioned that company's mine lab has not been certified, and therefore results could be different for assays obtained at an independent certified lab. The company however notes that drill hole assay results obtained and reported on its most recent press release were assayed at both the mine lab and independent ALS Chemex, located in Hermosillo, Mexico, and results obtained were similar, within expected tolerance. The company intends to send future samples taken during planned trenching and drilling for independent lab analysis and at that time will implement an industry standard quality assurance quality control program for these targeted exploration zones.

Quality assurance/quality control (QA/QC)

An industry standard quality assurance/quality control (QA/QC) program was followed by the company for all 17 Nueva Esperanza drill hole samples with sample duplicates, standards and blanks inserted into the sample stream of all drill hole samples, all of which were analyzed by ALS Chemex, located in Hermosillo, Mexico, a certified independent laboratory.

Control samples were also included for samples analyzed at the Cerro Prieto analytical laboratory, but the facility is not certified, and results are used as a guide for exploration and should not be relied upon. Samples will be sent to an independent certified laboratory to confirm the results.
