Orex Awards Airborne Geophysical Contract for the San Luis del Cordero Silver-
Copper-Zinc Project in Durango, Mexico
Vancouver, BC -- Orex Minerals Inc. -- (TSXV: REX -- OTCQX: ORMNF) ("Orex"), is pleased to
announce that Geotech Ltd. has been selected to fly an airborne geophysical survey over the
San Luis del Cordero Project in Durango, Mexico. This project is a skarn and epithermal vein
hosted silver-copper-zinc district, located 155 kilometres northeast of the City of Durango in the
Mesa Central of northcentral Mexico.
Orex's President, Gary Cope says, "The importance of skarn-style mineralization in Mexico is on
the rise, as shown by new discoveries at Pan American’s La Colorada Mine and the ongoing work
of Southern Silver’s Cerro de las Minitas project. Orex’s San Luis del Cordero, like both of these
projects as well as the famous San Martin Mine in Zacatecas, are polymetallic skarns in the Mesa
Central of the prolific Silver Trend of Mexico."
Geotech Ltd. will fly a helicopter-borne “VTEMTM Plus” survey, with accompanying horizontal
magnetic gradiometer and radiometric surveys. VTEM, a Versatile Time Domain Electromagnetic
survey, is used to identify discrete conductive anomalies, as well as mapping lateral and vertical
variations in resistivity. The magnetics and first derivative of the magnetic field are useful for
identifying contacts and structures. The radiometric survey is particularly well suited for potassic
alteration mapping and lithological contrast.
The airborne survey will be conducted over a grid at 100 metres line-spacing for approximately
275 line-kilometres. Normal helicopter speeds of 80 to 100 km/hour are expected, with a data-
recording rate of 0.1 point per second. Thus, geophysical measurements are acquired
approximately every 2 to 3 metres along the survey lines.
Project Description
The Cordero project has undergone several phases of exploration, with multiple targets yet to
be explored. Mineral concessions cover 2,825 hectares. Old mine workings and mineralized
showings wrap around a Tertiary quartz-feldspar-porphyry intrusive. Jurassic and Cretaceous
country rock formations include limestone and calcareous sandstone and shale units. Diamond
drilling of 62 holes from the period 2000 to 2016 total approximately 16,400 metres.
There is a Technical Report on a Mineral Resource Estimate for the project, compliant with NI43-
101 and dated 2014, containing an Indicated Resource of 662,600 tonnes grading Ag 121 g/t, Cu
0.78 % and Zn 1.06 %, for a silver-equivalent of 240 g/t and 5.1 million ounces silver-equivalent.
In addition, there is an Inferred Resource of 2,785,300 tonnes grading Ag 144.4 g/t, Cu 0.75 %
and Zn 1.45 %, for a silver-equivalent of 273 g/t and 24.4 million ounces silver-equivalent.
For the purposes of silver-equivalent in the 2014 report, metal prices of Ag=$19/oz, Cu=$3.00/lb
and Zn=$0.90/lb were applied. This resource estimate was performed using a cut-off of 85 g/t
silver equivalent. The technical report was written by T.W. Hodson, P.Geo., an independent
Qualified Person, and has an effective date of 1 October 2014.
Orex considers the 2014 resource estimate as a “Historical Resource Estimate” performed by
previous operators. There has been drilling since that date, and as such this resource estimate
should not be relied upon as current. However, it is useful as an exploration guide for future
programs.
Geological comparisons have been drawn between the San Luis del Cordero skarn and vein
hosted mineralization and the mineralization styles at Cerro de las Minitas of Southern Silver
Exploration Corp in Durango State and the San Martin – Sabinas mining district of Industrias
Peñoles in Zacatecas State. Both of these mining districts are also on the Mesa Central.
Technical Information and Qualified Person
Ben Whiting, P.Geo., Vice President of Exploration for Orex Minerals Inc., is a Qualified Person as
defined in NI 43-101 and takes responsibility for the technical disclosure contained within this
news release.
Community Relations
As a part of ongoing community relations, surface access agreements have been signed with the
Ejido of San Luis del Cordero, as well as individual ranch owners.
