From surface; 0m to 368m grading 0.81% copper equivalent1,2
(0.59% copper, 0.28g/t gold)

Including; 0m to 232m grading 1.00% copper equivalent1,2
(0.74% copper, 0.33g/t gold)

Vancouver, British Columbia – Centenera Mining Corporation (“Centenera” or the “Company”) - (TSXV: CT, OTCQB: CTMIF) has received final batch of drill results from drill hole 18-ESP-025 at the Esperanza Copper-Gold Porphyry project.  Drill hole 18-ESP-025 collared in mineralization and continued to drill mineralized rock to end of hole (387m; hole abandoned due to drilling difficulties).  Mineralization remains open at depth.

Laboratory results have been returned (Table 1) for the entire drill hole grading 0.57% copper and 0.27g/t gold; 0.78% copper equivalent1,2.  This includes 232m from surface grading 0.74% copper and 0.33g/t gold; 1.00% copper equivalent1,2

“In a global context, the complete results from drill hole 18-ESP-025 compare well with drill results from peer copper deposits reported in Q1 this year; the drill hole would have ranked number three only being exceeded by two deep copper deposits (Table 2),” stated Keith Henderson, Centenera’s President & CEO. “Looking at the comparison table it is important to remember that Centenera’s drill intersection is the only one starting from surface. Other factors such as location with respect to infrastructure also upgrade the Esperanza intersection relative to deposits in more remote locations.”

Notes 1 True width is not known.  2 Copper equivalent = Copper grade % + (0.795 x gold grade g/t), where the conversion factor of 0.795 is calculated by comparing the value of copper $2.20/lb to the value of gold at $1,200/oz and assuming 100% recovery.

Table 2:  Comparison between drill hole 18-ESP-025 and global top ten copper drill intersections published in Q1 2018.

Notes 1 Ranking is achieved by multiplying copper % by intersection meters.  Note that the ranking is of projects where copper is the primary commodity and does not take account of other commodity credits.  Esperanza has gold credits that are not included in the calculation.  Note also that mineralization in drill hole 18-ESP-025 is the only intersection that begins from surface.


Figure 1:  East-west cross section showing complete results from 18-ESP-025 and previous drill holes. The exploration vector to higher grade copper and gold is interpreted to be west, where two target drill holes are highlighted. Note that all drill holes on the section are open at depth and there is significant untested ground located to west and east.

Sction line locations for Figures 1 and 3 are also shown as well as select drill hole traces for targets. 

About Esperanza Copper-Gold Porphyry
The outcropping copper-gold porphyry mineralization at Esperanza was first drill-tested in 2006-2007 by 7 drill holes totalling 2,011 metres.  All drill holes intersected significant copper-gold mineralization.  Drilling highlights include:

  • Mineralization is outcropping at surface with a pyrite halo extending over a 1,400m x 850m area
  • Drill holes generally intersected mineralization at surface
  • Mineralization is open in all directions
  • Majority of drill holes terminated in mineralization and are open at depth
  • Several drill holes demonstrate increasing grade with depth

Quality Assurance / Quality Control

Drilling undertaken by Centenera in 2018 has been supervised by on site personnel at the project who rigorously collect and track samples, which are then sealed and shipped to SGS Minerals (“SGS”) for analysis.  SGS's quality system complies with the requirements for the International Standards ISO 9001:2000 and ISO 17025: 1999.  Analytical accuracy and precision are independently controlled by company using blanks, control reference material and duplicate samples.

About Centenera Mining Corporation

Centenera is a mineral resource company trading on the TSX Venture Exchange under the symbol CT and on the OTCQB exchange under the symbol CTMIF.  The Company is focused 100% on mineral resource assets in Argentina.  The Company intends to focus its 2018 exploration activities on drill-testing its flagship Esperanza copper-gold project.

Other assets include the El Quemado lithium pegmatite project in Salta Province and the Organullo gold project.  The Organullo project has approximately 8,000 metres of historical drilling and assay results.  Organullo has a geological target range from 19.8 million tonnes grading at 0.94 g/t gold (600,000 ounces) to 31.6 million tonnes grading 0.92 g/t gold (940,000 ounces) using a 0.5 g/t gold cut-off-grade. It should be noted that these potential exploration target quantities and grades are conceptual in nature, that insufficient exploration and geological modelling has been done to define a mineral resource, and that it is uncertain if further exploration will result in the delineation of a mineral resource.
