Drilling Results Demonstrate the Potential to Significantly
Expand the Initial Inferred Mineral Resource at Alacran
TORONTO, ONTARIO, January 11, 2017: Cordoba Minerals Corp. (TSX-V:
CDB) (“Cordoba” or the “Company”) and its joint-venture partner, High
Power Exploration Inc. ("HPX"), a private mineral exploration company
indirectly controlled by mining entr epreneur Robert Fr iedland’s Ivanhoe
Industries, LLC, are pleased to announ ce that drilling at the San Matias
Copper-Gold Project in Colombia has si gnificantly expanded the volume of
near-surface copper-gold mineralizatio n at the Alacran Deposit. Copper
mineralization at Alacran ha s 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 (ref er to Table 1 for complete drilling
results):
ACD028:
24 metres (m) @ 1.64% Copper (Cu) + 0.62g/t Gold (Au) (from
42 m), including:
6 m @ 1.97% Cu + 0.91g/t Au (from 50 m), and
4 m @ 3.69% Cu + 1.06g/t Au (from 62 m)
ACD032:
66 m @ 1.20% Cu + 0.23g/t Au (from 46 m), including:
14 m @ 3.31% Cu + 0.26g/t Au (from 60 m), and
6 m @ 1.95% Cu + 0.72g/t Au (from 98 m)
ACD033:
108 m @ 1.26% Cu + 0.87g/t Au (from 0 m), including:
26 m @ 1.48% Cu + 1.37g/t Au (from 20 m), and
26 m @ 3.18% Cu + 1.62g/t Au (from 62 m)
ACD035:
34 m @ 0.75% Cu + 0.47g/t Au (from 6 m), including:
18 m @ 1.20% Cu + 0.74g/t Au (from 22 m)
60 m @ 0.40% Cu + 0.21g/t Au (from 122 m)
Hole ACD033 (108 m @ 1.26 % Cu + 0.87g/t Au) has returned one of the
best intersections to date on the proj ect with mineralization outside the
current Inferred Mineral Resource shell. The recent drilling results
demonstrate the potential to signifi cantly 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 rel ease January 5, 2017 (see Figure
7). The area around hole ACD033 is a pr iority 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-s outh direction, with a sub-vertical
westerly dip. This drillin g campaign has shown th at the mineralization
dips more moderately to the west, c onformable to the host stratigraphy,
adding additional shallow mineralization up-dip to the east. Moving from
north to south, the host stratigrap hy appears to steepen while the
mineralization changes fr om pyrrhotite-pyrite-chalcopyrite to magnetite-
chalcopyrite. Based on magnetic a nd 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 Al acran to host a large high-grade,
open-pittable, copper–gol d deposit. Current dril ling at Alacran will
continue to test the eastern extensi ons 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 nort hern 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 infrastruc ture 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 associat ed 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, exploratio n and research industries. Dr. Grainger is a
Member of the Australian Institute of Geoscientists (AIG).
Copper-equivalent values have been calculat ed 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 addi tional 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 regu lar 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.
