Vancouver, British Columbia--(Newsfile Corp. - December 14, 2016) - Minaurum Gold, Inc. (TSXV: MGG) ("Minaurum") is pleased to announce it has identified three new targets along a 2.5km section of the 7.5-km long epithermal vein system located at the La Quintera Silver Project in southern Sonora State. This area contains the La Quintera and Promontorio mines, which are estimated to have produced more than 140 million ounces of silver from 1680 to 1910. Geological mapping and sampling continue in the three target areas, as well as in additional potential targets on parallel zones.
La Quintera Mine Target:
The La Quintera vein was mined along approximately 800m of strike length and to depths of 500m. Minaurum's research of historical records indicates that labor disputes on the eve of the Mexican Revolution led to the ceasing of mining activities while still in silver mineralization averaging 40 oz/t Ag and 8% Cu. In addition, one of the four major ore shoots defined at the mine was not developed. Minaurum's mapping and sampling has discovered a new vein running parallel to the principal vein. This parallel vein along with the down-dip extension of known mineralization in the La Quintera vein form the primary targets. Highlights of Minaurum's sampling along with historical results dating back to 2013 are presented in Table 1.

Gap Target:
The Gap is a 500-metre long zone between the southernmost workings of the La Quintera mine and the northernmost workings of the Promontorio mine. The Gap, for various historical reasons, was not developed even though the same surface geological elements as at the La Quintera and Promontorio mines are present. Minaurum has mapped multiple semi-continuous quartz veins over more than 300 metres of strike length in the Gap. Additional sampling and mapping is underway in the Gap area. The Gap has the potential to host an unexploited silver shoot. See Table 2 for the sampling highlights.

Promontorio Mine Target:
At the Promontorio target, the La Quintera vein was developed over a strike length of 800m and locally to depths of 200m below the level of the Promontorio adit. As at the La Quintera Mine, labor disputes in the years before the Mexican Revolution stopped mining while still in high-grade silver mineralization. Based on Minaurum mapping and sampling, the immediate target is the down-dip extension of known workings along with the potential for mineralized structures parallel to the principal vein. Base-metal and gold values are consistently higher at Promontorio area than at the other targets. Highlights of Minaurum's and historical sampling at Promontorio are presented in Table 3.

"As we advance the first systematic exploration program undertaken in this historical district, we continue to identify new high-grade silver targets," stated Darrell Rader, President and CEO of Minaurum. "The targets reported above demonstrate the potential of this project to host both new, unexploited silver shoots along with down-dip extensions of the historical silver deposits."
The three new targets lie in the southern part of the 7.5 km long Promontorio-La Quintera vein system that is the focus of the ongoing drill-target generation program consisting of geologic mapping and geochemical sampling. Nearly 200 rock samples have been taken by Minaurum to date, in addition to more than 300 samples in the historical database.
