Cordoba Minerals Announces Additional High Grade Copper-Gold Mineralization at the Alacran Deposit in Colombia
New Visible Gold Intersected with Assays Pending
TORONTO, ONTARIO--(Marketwired - May 17, 2017) - Cordoba Minerals Corp. (TSX VENTURE: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 ongoing drilling at the Alacran Project in Colombia, has continued to encounter high grade copper-gold mineralization.
Recent drill holes have recorded mineralized intercepts of up to 184 metres, many with gold and copper mineralization that are significantly higher than the grades used in the preliminary Inferred Mineral Resource statement with the potential to expand the resource envelope.
Drilling also has resulted in an enhanced understanding of the structural controls to the mineralization, providing good targets for future drilling. In addition, drilling has confirmed additional intersections of the carbonate base metals (CBM) veins, which host the bonanza-grade gold mineralization previously intersected in hole ACD036 (see January 23, 2017 news release).

Mario Stifano, President and CEO of Cordoba, commented: "Drilling at Alacran continues to identify near surface high grade copper-gold mineralization with additional CBM veins intersected in multiple holes over a 400 metre structural trend, indicating potential to identify additional bonanza grade zones and veins. Our geological understanding of the multiple mineralizing events and structural interpretation at Alacran is improving with visible gold recently intersected in drill hole ACD063, with assays pending. With strong community support, the Company is now positioned to drill deep holes around the artisanal mine workings to identify the source of the higher-grade gold and copper mineralization and target additional CBM veins at Alacran."
Gold-rich zones at the Alacran project are associated with CBM (carbonate base-metal) style veining that has a zinc-gold association and is interpreted to be a later event overprinting the copper-gold mineralization. Recent drilling analysis has shown that a north-south striking, steeply west-dipping, diorite dyke has been noted in a number of holes. This dyke appears to have a very strong correlation with high grade Cu-Au replacement mineralization and also appears to have a close affinity with high grade gold, such as the bonanza gold grade reported previously in ACD036 (0.90 meters @ 4,440 g/t gold, 10.25% copper, 24.70% zinc and 347 g/t silver). A direct magmatic-related association between high-grade copper-gold, and potentially the gold-zinc CBM veining, adds additional potential high-grade drill targets over a considerable strike length of the Alacran known mineralization.
The relationship of this dyke to mineralization is outlined in Figure 2, where additional high-grade gold has been intersected in ACD041 (2 metres @ 9.82 g/t gold, 1.57% copper), in ACD050 (2 metres @ 11.15 g/t gold, 1.3% copper and 2 metres @ 7.36 g/t gold, 1.56% copper) and ACD58 (2 metres @ 3.4 g/t gold, 8.89% copper). There is potential to follow this body down dip to the west for additional replacement-style mineralization. Another primary control on late high-grade gold mineralization at Alacran is a NNE striking fault corridor which appears to control a series of en-echelon CBM style veins (as seen in ACD036). The gold in these veins is coarse and highly "nuggety", but values typically return in excess of 5 g/t gold.
Diamond drilling, aided through detailed structural interpretation of previously intersected CBM style mineralization, will target these zones in the ongoing drill program at the Alacran project.
Discussion
Twenty-two drillholes have been completed at the Alacran project that focused on lateral extensions and continuity of copper-gold mineralization related to higher-grade zones between drill sections that to date, are drilled on approximately 100 metre spaced drill fences. Drilling was concentrated on the northern parts of the known copper-gold mineralization, some of the key results are discussed below.
On Section 855825mN one drillhole was collared to test obliquely to the south the continuity of copper-gold mineralization between sections.
- ACD047 intersected 128 metres @ 0.80% copper and 0.24 g/t gold (0.98% CuEq) from surface and demonstrated higher than average grades for both copper and gold from surface over a significant interval.
On Section 855680mN,
- ACD058 was drilled obliquely to the south to test the continuity of copper-gold between sections and successfully intersected a number of copper-gold rich zones that are significantly higher than the preliminary resource grades for both copper and gold. These are outlined in Table 1 and include:
- 80 metres @ 0.43% copper and 0.22 g/t gold (0.60% CuEq) from 114 metres

Section 855570mN, six drillholes were collared; some to test the up-dip extensions to the orebody on section and some drilled oblique to section, both north and south, to better determine the short distance variation in both copper and gold grades. The copper-gold mineralization remains open down-dip on section.
- ACD050 was an oblique drillhole drilled to the south east to test the continuity of higher-grade copper-gold mineralization between section that successfully intersected multiple, large intervals of copper-gold mineralization as noted in Table 1, and include
- 42 metres @ 0.55% copper and 1.25 g/t gold (1.51% CuEq) from 76 metres.
- ACD041 was drilled to the west to better define structural controls of stratigraphy on copper-gold mineralization down-dip and successfully intersected a large interval of copper-gold mineralization that incorporated 184 metres @ 0.46% copper and 0.28 g/t gold (0.67% CuEq) from 6 metres and included a number of higher-grade intervals as outlines in Table 1 including:
- 12 metres @ 1.04% copper and 2.44 g/t gold (2.90% CuEq) from 16 metres, and

Alacran Copper-Gold Project
The Alacran Copper-Gold project is located within the Company's San Matias Copper-Gold Project in the Department of Cordoba, Colombia. The Alacran project is located on a topographic high in gently rolling topography, optimal for potential open-pit mining. Access and infrastructure are considered favourable. The Alacran initial, pit-constrained, Inferred Mineral Resource is 53.52 million tonnes at 0.70% copper and 0.37 g/t gold, or 0.95% copper equivalent (CuEq), including 7.37 million tonnes at 2.14% copper and 0.41 g/t gold above 1% copper (Cu) cut off (see news release dated January 5, 2017.
Alacran is approximately two kilometres southwest of the Company's Montiel porphyry copper-gold discovery, where drilling intersected 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 intersected 87 metres of 0.62% copper and 0.51 g/t gold. 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 or skarn zones and associated disseminations. 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 a large-scale early magnetite metasomatic event.
About San Matias Project
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. Porphyry mineralization at the San Matias Project incorporates high-grade zones of copper-gold mineralization hosted by diorite porphyries containing secondary biotite alteration and various orientations of sheeted and stockwork quartz-magnetite veins with chalcopyrite and bornite. The copper-gold skarn mineralization at Alacran is associated with stratabound replacement of a marine volcano-sedimentary sequence. The nature of mineralization encountered at San Matias is similar to other large high-grade copper-gold deposits.

- 0.3% CuEq cutoff with 6m maximum internal dilution and a 6m minimum width.
- 1.0% CuEq cutoff uses 4m maximum internal dilution and 4m minimum width.
- True width intervals of the mineralization are estimated in the rightmost column.
- Copper equivalent (CuEq) 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 % CuEq.
