17-15 - Numerous Targets Identified at Bramaderos Gold-Copper project in Ecuador - Outcropping mineralization evident

June 6, 2017

Ottawa, ON, Canada: Cornerstone Capital Resources Inc. ("Cornerstone" or "the Company") (TSXV-CGP) (F-GWN) (B-GWN) (OTC-CTNXF) is pleased to provide further information on the recent highly successful initial field visit at the Bramaderos Gold-Copper Project in southern Ecuador where its subsidiary La Plata Minerales S.A. ("PLAMIN") has signed a binding letter of intent with Avalon Minerals Ltd. (ASX: AVI) whereby Avalon will have the right to earn a majority interest in the 4,949 hectare "Bramaderos" concession subject to satisfaction of certain conditions.

  • Field investigations at Bramaderos have identified several target areas for high priority follow-up exploration
  • Assessment of known mineralized areas also highlights significant exploration potential
  • Follow-up exploration on track to start later this month
  • Assays from rock chips samples due within four weeks


The initial field program was aimed at further defining and prioritizing the exploration program which is due to commence later this month.

Thirteen surface rock chip samples were collected across multiple prospects within the property. These have been submitted to the MS Analytical Laboratory sample preparation facility in Ecuador. Assaying will be carried out in Vancouver, Canada. Assay results are expected in late June.

Figure 2 shows location and photographs from main prospects identified so far on the Bramaderos property.

Photographs from figures 3 and 4 show outcrops from the Limon gold-copper prospect exhibiting surface mineralization, and intense stockwork and sheeted quartz veining indicative of a porphyry-style mineralized system. The area of veining at surface is surrounded at a more regional scale by extensive areas of intense argillic alteration which is interpreted to represent an epithermal alteration overprint.

Previous rock chip sampling in the Limon area has returned up to 1.8% Cu and 1.45g/t Au in rock chip samples, and paired samples of 1.24g/t Au and 0.23% Cu, and 1.45g/t Au and 0.45% Cu. Historic soil sampling has defined areas of coincident Cu, Au and Mo anomalies over an area of approximately 1.4km x 0.5km. This prospect has never been drill tested.

A proposed work program commencing in June across the Bramaderos Project comprises:

  • Re-processing of existing ground magnetic data;
  • Collection of additional ground magnetic data in areas not previously covered;
  • Detailed geological mapping and rock chip sampling at each of Bramaderos main, Porotillo, Melonal, Limon and West Zone prospects;
    • Trenching at the West Zone prospect to follow up historical trenching of 41.7m @ 3.7g/t Au;
    • Alteration mapping to provide vectors to mineralization;
    • Regional mapping and sampling in areas not previously explored and yet exhibit potential outcropping mineralization such as Yeso and Ghangue prospects in the south.
