Drilling Results Demonstrate the Potential to Significantly Expand the Initial Inferred Mineral Resource at Alacran
TORONTO, ONTARIO--(Marketwired - Jan 11, 2017) - Cordoba Minerals Corp. (TSX VENTURE:CDB) ("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 significantly expanded the volume of near-surface copper-gold mineralization at the Alacran Deposit. Copper mineralization at Alacran has now been intersected over a strike length of 1.3 kilometres, to widths of up to 400m, and extends from surface to depths of more than 260 metres below surface.
Recent Alacran drilling highlights (refer to Table 1 for complete drilling results):

Hole ACD033 (108 m @ 1.26% Cu + 0.87g/t Au) has returned one of the best intersections to date on the project with mineralization outside the current Inferred Mineral Resource shell. The recent drilling results demonstrate the potential to significantly increase the current inferred mineral resource at Alacran of 53.5 million tonnes of 0.70% copper and 0.37 g/t gold announced in a press release January 5, 2017 (see Figure 7). The area around hole ACD033 is a priority target to follow-up with additional drilling to the east, where the mineralization remains open.
Prior to the current drilling program, the mineralization at Alacran was believed to be striking in a north-south direction, with a sub-vertical westerly dip. This drilling campaign has shown that the mineralization dips more moderately to the west, conformable to the host stratigraphy, adding additional shallow mineralization up-dip to the east. Moving from north to south, the host stratigraphy appears to steepen while the mineralization changes from pyrrhotite-pyrite-chalcopyrite to magnetite-chalcopyrite. Based on magnetic and induced polarization surveys, attractive exploration targets remain down-plunge and along strike.
Mario Stifano, President and CEO of Cordoba, commented: "These drill results highlight the potential for Alacran to host a large high-grade, open-pittable, copper-gold deposit. Current drilling at Alacran will continue to test the eastern extensions of the deposit as well as priority exploration to identify and target the potential 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. Alacran is approximately two kilometres 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 kilometres northwest of the Costa Azul porphyry copper-gold discovery, where drilling interested 87 metres of 0.62% copper and 0.51 g/t gold (Figure 1). 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 disseminations (Figure 2). 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-standard 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 additional elements is analyzed by four-acid digest with an ICP-ES or ICP-MS finish. All 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.
Cordoba also performs check assays on a regular basis at an independent laboratory. The company regularly conducts independent onsite reviews and laboratory audits to ensure procedural compliance for maintaining industry-standard best practices. Selected samples of elevated gold grades have been submitted to ALS Lima for metallic screen analysis for the possible presence of coarse gold, assays are pending.
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.

*Intercepts calculated using a: |
0.3% eCu cutoff with 6m maximum internal dilution and a 6m minimum width. |
1.0% eCu cutoff uses 4m maximum internal dilution and 4m minimum width. |
2.0% eCu cutoff uses 2m maximum internal dilution and 2m minimum width. |
The "includes" & "and" intercepts are found within the preceding intercept, and represent higher grade portions therein. |
True width intervals of the mineralization are interpreted as being between 90-100% true widths from oriented diamond drill core and sectional interpretation. |
Copper equivalent (eCu) calculations assume a US$2.50/lb copper price and a US$1300/Oz gold price. |
For intercept calculations: sample assays of copper, gold and copper equivalent are all capped to 10% Cu, 10 g/t Au, and 10 % eCu. |
