Cordoba Minerals Corp. provides company update

TORONTO, ONTARIO--(Marketwired - Oct. 26, 2017) - Cordoba Minerals Corp. (TSX VENTURE:CDB)(OTCQX:CDBMF) ("Cordoba" or the "Company") is pleased to announce an update on its ongoing resource expansion program at the high-grade, near-surface Alacran Deposit (located within the San Matias Copper-Gold Project in Colombia), as well as other ongoing activities.

Drill Program - September/October, 2017

Cordoba is pleased to report that five out of the ten planned drill holes at Alacran have been successfully completed. The Company continues to work diligently to complete the remainder of the planned drill campaign. Drilling is taking place in two main fronts aimed at extending the resource in the immediate vicinity of an internally modeled pit shell.

• Down-dip extension to the west: the two step-out holes drilled so far in the northwestern portion of the deposit (ACD070 and 71) were successful at proving down dip continuation of the copper-gold mantos with wide intersections of abundant chalcopyrite mineralization. This is particularly impressive in hole ACD070 where the stratabound copper-gold mineralization is overprinted by a discordant metre-wide fault zone filled with semi-massive sulfides. Predominance of arsenopyrite (plus minor pyrite and sphalerite) coupled with the pervasive sericite-illite alteration and carbonate gangue is diagnostic of a low sulfidation epithermal vein event. Assay results are pending.
  
  
• Southern extension of Alacran: three step-out holes (ACD067, 69 and 72) were completed, adding 100 metres of strike length to the south of the shallow ore grade intercept that was reported in July for hole ACD066 (48 metres @ 0.70% copper and 0.19g/t gold). Assay results are also pending for these holes.
  
  

Mario Stifano, President and CEO of Cordoba, said, "We are encouraged by our team's progress toward our immediate goal of publishing an updated Resource Estimate at the Alacran Deposit. The exciting discovery of new epithermal veins increases the likelihood for additional high-grade gold at Alacran and it remains unclear if they are related to previously reported high-grade gold bearing Carbonate Base Metal (CBM) veins. The down dip continuation of mineralization at northern Alacran has the potential to significantly increase the size and tonnage of the deposit. In addition, the potential relationship of the epithermal veins to the large soil anomaly and intrusive immediately north of Alacran needs to be explored."
