Centenera Announces Brokered Private Placement for Proceeds of up to $2 Million

In consideration for its services, the Lead Agent will receive a corporate finance fee consisting of a cash payment equal to 2% of the gross proceeds of the Offering and non-transferable broker warrants (the "Broker Warrants") equal to 2% of the total number of Shares issued by the Company under the Offering. Each Broker Warrant will be exercisable for 30 months following the closing of the Offering to acquire one Share at the issue price of $0.16 per Share. In addition, the Lead Agent will receive a sales commission comprised of a cash payment equal to 5% of the gross proceeds of the Offering and Broker Warrants equal to 5% of the total number of Shares issued by the Company under the Offering. Closing of the Offering is anticipated on or around August 21, 2017.

The net proceeds from the Offering will be used for exploration of the Company's mineral properties and for general working capital. The Company is focused in its Huachi copper-gold porphyry project ("Huachi") located in San Juan Province, Argentina. In connection with acquisition of the project in January 2017, Centenera commissioned a 43-101 technical report which is available for download at the Company's home page together with a corporate presentation. The 43-101 report confirmed the results from a previous drill program conducted in 2007. The copper-gold porphyry deposit has been tested with a total of 7 diamond drill holes (totalling 2,011 meters), the results of which can be found in the NI 43-101 report. Highlights include:

• -All drill holes targeting porphyry style mineralization intersected copper-gold mineralization.

  -Best intersection to date is 353.1m1 from surface, grading 0.35% copper and 0.18g/t gold (0.49% copper equivalent2), including 243.1m1 grading 0.40% copper and 0.21g/t gold (0.57% copper equivalent2).

  -Mineralization is outcropping at surface (pyrite halo 1,400m x 850m) and drill holes generally intersected mineralization at surface.

  -Mineralization is open in all directions.

  -Majority of drill holes terminated in mineralization (due to limitations of the drill rig) and are open at depth.

  -Several drill holes demonstrate increasing grade with depth.

Notes: 1 True width is not known. 2.Copper equivalent = Copper grade % x (0.795 x gold grade g/t), where the conversion factor of 0.795 is calculated by comparing the value of 1 tonne of copper ore (at copper prices of $2.20/lb ($4,850.16/t)) to the value of 1 tonne of gold ore (at $1,200/oz ($38.58g/t)) and assuming 100% recovery.

In recent weeks, the Company completed a ground magnetic survey covering part of the project area and surface rock sampling in areas where sampling had not previously been completed. The results, when available, will be used to finalize drill targets at Huachi. The Company has applied for drill permits and the Company's exploration manager is working to finalize same.

The objective of future drilling will be to investigate the tonnage potential at Huachi. The planned drill holes are expected to step out at least 100m from previous drill holes. Since previous drill holes are open at depth, planned holes will aim to reach 500m to 600m in total drill length.

San Juan is a Province of Argentina which is known to be supportive of mining with several large mines currently in operation. Access to infrastructure is critically important and impacts the feasibility of bulk-tonnage porphyry-style projects. Huachi is close to existing infrastructure, being only 35km from the electrical transmission lines that service Yamana's Gualcamayo Mine and with planned road upgrades, it will be possible to access the project by road throughout the year. Huachi is located at low elevations of between 2,800m and 3,250m above sea level, which is low relative to projects in the high Andes at greater than 4,500m.

About Centenera Mining Corporation

Centenera is a mineral resource company trading on the TSX Venture Exchange ("TSXV"), under the symbol CT and on the OTCQB exchange under the symbol CTMIF. The Company is focused 100% on mineral resource assets in Argentina. In 2017 the Company's strategy is to focus on the Huachi project (see news releases dated January 23 and March 6, 2017). The Company intends to focus its Q3/Q4 efforts on drill-testing.

Other assets, such as the El Quemado project in Salta Province (see news release dated April 26, 2017) are intended to be explored by the Company with the aim of proving project potential and attracting a joint venture partner or a project sale. The Company intends to seek a joint venture partner for the Organullo gold project, which has approximately 8,000 meters of historical drilling and assay results. The Organullo project 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 at 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 completed to define a mineral resource, and that it is uncertain if further exploration will result in the delineation of a mineral resource.
