Phase-V Exploration Diamond Drilling Completed on the Coneto Gold-Silver Project in Durango, Mexico

VANCOUVER, March 24, 2017 /PRNewswire/ - Orex Minerals Inc. -- (TSX-V: REX --OTCQX: ORMNF) ("Orex"), announces that project partner Fresnillo PLC (LSE: FRES -- BMV: FRES) ("Fresnillo"), has completed a Phase-V exploration diamond drilling program of 11 holes on the Coneto Gold-Silver Project in Durango, Mexico.

The Coneto Project is a joint venture, with ownership of 55/45% between Fresnillo and Orex. A Technical Committee, with membership from both companies, guides the exploration programs.

The Phase-V drilling program tested a variety of targets across the Coneto property. In total, there were 5,214.90 metres in 11 holes. Three holes were drilled in the Northern Zone (La Bufa, Santo Niño), three holes in the Western Zone (Loma Verde), four holes in the Southern Zone (Durazno, Nogales, Promontorio) and one hole in the Central Zone (Descubridora).

Orex's President, Gary Cope says, "This drilling program continues to expand our understanding of the multiple structures on the Coneto Project and we are planning additional exploration with our colleagues at Fresnillo."

Silver-equivalent is based on a gold price of $US 1,200/oz and silver price of $18/oz, for an Au:Ag ratio of 66.67:1, and it does not include any base metal credits. Recovery is assumed to be at 100% for the purpose of the silver-equivalent.

The thickest intercepts were in the Durazno Vein, although the grades were not particularly high in the areas tested. However, this does indicate that the structures continue at depth. A Durazno intercept of 44.75 metres core length (31.64 m true thickness) yielded gold 0.42 g/t and silver 2 g/t for a silver-equivalent of 30 g/t. There is also a gold-rich vein in the hanging wall of Durazno, which yielded 1.30 metres core length (0.92 m true thickness) grading gold 4.71 g/t and silver 4 g/t for a silver-equivalent of 318 g/t.

The Nogales Vein, east of Durazno-Impulsora, intercepted 1.25 metres core length (0.88 m true thickness) grading gold 0.40 g/t and silver 402 g/t for a silver-equivalent of 428 g/t.

A hanging wall structure east of Loma Verde yielded 9.05 metres core length (3.0 m true thickness) grading gold 0.34 g/t and silver 9 g/t for a silver-equivalent of 32 g/t. Within this was a sub-interval of 1.60 metres core length (1.22 m true thickness) grading gold 1.50 g/t and silver 28 g/t for a silver-equivalent of 128 g/t.

The lone hole in Descubridora Vein intercepted 7.70 metres core length (4.94 m true thickness) grading gold 0.42 g/t and silver 27 g/t for a silver-equivalent of 55 g/t. Within this was a sub-interval of 1.45 metres core length (0.93 m true thickness) grading gold 1.01 g/t and silver 67 g/t for a silver-equivalent of 134 g/t.

The Company also announces that it has entered into a non-arm's length shared services agreement dated January 1, 2017 with Belcarra Group Management Ltd. ("Belcarra"), whereby Orex has engaged Belcarra to provide management, administrative, office facilities and other related services including the provision of personnel as may be required by the Company from time to time (the "Shared Services"). The Shared Services are to be provided and the costs are to be allocated on a shared and proportional basis with certain other companies that have also engaged Belcarra to provide the Shared Services. Orex notes that Belcarra is a non-arm's length party, as Belcarra is controlled by Gary Cope, the Company's President and CEO.

Coneto Mining District -- Durango, Mexico

The historic Coneto Mining District is situated in the heart of the "Mexican Silver Trend", on the Mesa Central, stretching from Guanajuato in the southeast, through to the states of Zacatecas and Durango. This prolific trend hosts some of the world's largest silver camps and deposits, including Fresnillo, Guanajuato, La Pitarrilla, La Preciosa, Real de Angeles and Zacatecas.

The silver and gold mineralization at Coneto is of intermediate sulphidation style epithermal veins hosted in Tertiary andesites and rhyolites.

Orex and Fresnillo hold, through Exploraciones y Desarrollos Mineros Coneto S.A.P.I. de C.V., an extensive contiguous land package of mineral concessions in the Coneto Mining District, which collectively total approx. 10,600 hectares and cover multiple mineralized epithermal quartz veins. In the first five phases, Orex and Fresnillo drilled 104 holes totaling about 38,600 metres. Locations for the diamond drill holes will be posted on the Orex Minerals Inc. website.
