Copper, 24.7% Zinc and 347 g/t Silver over 0.9 Meters
in New Discovery
TORONTO, ONTARIO, January 23, 2017 : Cordoba Minerals Corp. (TSX-V:
CDB; OTCQX: CDBMF) (“Cordoba” or the “Company”) and its joint-venture
partner, High Power Exploration Inc. (" HPX"), a private mineral exploration
company indirectly controlled by mining entrepreneur Robert Friedland’s
Ivanhoe Industries, LLC, are pleased to announce that drilling at the San Matias
Copper-Gold Project in Colombia has intersected bonanza gold veins at
Alacran. The discovery of this new style of high grade gold mineralization
represents a separate and significant exploration opportunity at Alacran.
Alacran drilling highlights:
ACD036:
0.90 meters (m) @ 4, 440 g/t gold (Au) + 10. 25% copper (Cu) +
24.70% zinc (Zn) + 347 g/t silver (Ag)
Part of
5.00 m @ 800.90 g/t Au + 3.70% Cu + 8.60% Zn + 88.63 g/t Ag
136.00 m @ 1.00% Cu + 0.56 g/t Au (cut*)
The 0.90 meter bonanza grade gold inters ection in ACD036 is hosted in a
late stage, chalcopyrite-sphalerit e-carbonate-coarse gold vein that
overprints earlier chal copyrite-pyrrhotite coppe r-gold mineralization
(Figure 1). The high-grade gold vein is similar to Carbonate Base Metal
(CBM) vein systems found globally, including Barrick Gold’s Porgera gold
mine and also Continental Gold’s Bu ritica deposit, located south of
Cordoba’s licenses along the Mid Cauca belt in Colombia.
The discovery of these st ructurally controlled high-grade gold rich veins
represents an important new target to add extremely high value material
within the existing inferred copper -gold mineral resource shell and
resource expansion. The CBM Vein in ACD036 was intersected at a depth
of approximately 90 meters below surf ace. Copper-gold mineralization at
Alacran has now been intersected over a strike length of 1.3 kilometres, to
widths of up to 400 meters, and extends from surface to depths of more
than 260 meters below surface.
Mario Stifano, President and CEO of Cordoba, co mmented: “We are
excited by the discovery of bonanza gr ade gold in CBM veins as this new
style of mineralization adds anothe r significant exploration front to
potentially increase the size and scope of mineraliza tion at Alacran. We
are still in the very early stages of our aggressi ve exploration program at
our district scale San Ma tias copper-gold project, but our best in class
exploration team and HPX’s proprietary Typhoon technology, reminds us
that anywhere, anytime, there is pote ntial for a significa nt discovery at
San Matias”.
Drilling at Alacran will now focus on testing the up-dip eastern extensions
of the deposit, the ext ent of the newly discover ed CBM veins including
structural controls and the potenti al source for the mineralization at
Alacran.
Alacran Copper-Gold System
The Alacran copper-gold system is located within the San Matias Copper-Gold Project in the
Department of Cordoba, Colombia. The San Matias Copper-Gold Project comprises a 20,000-
hectare land package on the inferred northern extension of the richly endowed Mid-Cauca Belt
in Colombia. The project contains several known areas of porphyry copper-gold
mineralization, copper-gold skarn mineralization and vein-hosted, gold-copper mineralization.
The Alacran system is located on a topographic high in gently rolling topography, optimal for
potential open-pit mining. Access and infrastructure are considered favourable. Initial inferred
resources at Alacran are 53.5 million tonnes of 0.70% copper and 0.37 g/t gold . Alacran is
approximately two kilometers southwest of the Company’s Montiel porphyry copper-gold
discovery, where drilling interested 101 metres of 1.0% copper and 0.65 g/t gold , and two
kilometers northwest of the Costa Azul por phyry copper-gold discovery, where drilling
interested 87 metres of 0.62% copper and 0.51 g/t gold (Figure 2). The copper-gold
mineralization at Alacran is associated with stratabound replacement of a marine volcano-
sedimentary sequence in the core of a faulted antiformal fold structure. The deposit comprises
moderately to steeply-dipping stratigraphy that is mineralized as a series of sub-parallel
replacement-style zones and associated dissem inations. The copper-gold mineralization is
composed of multiple overprinting hydrothermal events with the main ore phase comprised of
chalcopyrite-pyrrhotite-pyrite that appears to overprint an early magnetite metasomatic event.
Technical Information
The technical information has been reviewed and verified by Christian J. Grainger, PhD, a
Qualified Person for the purpose of NI 43-101. Dr. Grainger is a geologist with over 15 years
in the minerals mining, consulting, exploration and research industries. Dr. Grainger is a
Member of the Australian Institute of Geoscientists (AIG).
Copper-equivalent values have been calculated using a US$1,300 per ounce gold price and
US$2.50 per pound copper price.
Cordoba utilizes a comprehensive industry-st andard QAQC program. HQ and NQ diamond
drill core is sawn in two halves, and one half is sampled and shipped to a sample preparation
laboratory. The other half of the core is stored in a secure facility for future assay verification.
All samples are prepared at ALS Minerals Laboratory in Medellin, Colombia, and assayed at
ALS Minerals Laboratory in Lima, Peru. ALS Minerals operates in accordance with ISO/IEC
17025.
Gold is determined by 50 g fire assay with an AAS finish. An initial multi-element suite
comprising copper, molybdenum, silver and addi tional elements is analyzed by four-acid
digest with an ICP-ES or ICP-MS finish. Al l samples with copper values over 2000 ppm are
re-assayed by a method for higher grades, which also uses a four-acid digest with an ICP-ES
finish.
Selected samples of elevated gold grades are submitted to ALS Lima for metallic screen
analysis to accurately represent grades given the presence of coarse gold.
The exact location of ACD036 drill hole collar has not been disclosed for strategic business
purposes.
Joint Venture Agreement
The San Matias Project is a joint venture between Cordoba and HPX. HPX has earned a 51%
interest in the San Matias Project by spending a cumulative total of C$19 million on
exploration expenditures on the project. Cordoba and HPX have entered Phase Three of their
Joint Venture Agreement, whereby HPX can earn a 65% interest in the project by completing
a Feasibility Study.
