Cornerstone Capital Resources Inc. (TSX-V:CGP) (Frankfurt:GWN1) (Berlin:GWN1) (OTC:CTNXF) is pleased to announce the following drilling update on its Tandayama-America porphyry copper-gold mineralized target located 3km north of the Alpala Deposit1 at its Cascabel copper-gold porphyry joint venture project in northern Ecuador in which Cornerstone has a 15% interest2 financed through to completion of a feasibility study plus 6.86% of the shares of joint venture partner and Project operator SolGold Plc, for a total direct and indirect interest in Cascabel of 20.8%.

Highlights
SolGold Executive Board Member and ENSA President, Jason Ward, commented on the results at TAM:
“Significant copper and gold mineralization at the TAM target will add to the already impressive metal inventory at Alpala. The recent drilling results at TAM are indicative of a significant prospective resource that appears amenable to bulk surface mining methods. This seems likely to have a major beneficial impact on the development of the Cascabel property as a whole and the further upside of a potentially significant deep target beneath TAM is certainly adding excitement to the growing possibilities at Cascabel.”
* The reader is cautioned that there has been insufficient exploration to define a mineral resource at TAM and it is uncertain if further exploration will result in the target being delineated as a mineral resource.
Further Information
The TAM target lies approximately 3km north of the Alpala Deposit, located on the Cascabel concession within Imbabura Province in northern Ecuador. The project area lies approximately 100 km north of the capital city of Quito and approximately 50 km north-northwest of the provincial capital, Ibarra (Figure 1).

Selected examples of mineralization encountered at TAM to date are provided in Figure 2.
Drilling at TAM continues with three diamond drill rigs and further expansion of the TAM drilling fleet is planned (Figure 3).
Cross sections through the centre of the target are provided in Figure 4.
The intersection of noteworthy porphyry stockwork mineralization encountered in Hole 9 in the deeper portions of the drilling area contains high abundance of B-type quartz-chalcopyrite veining (Figure 5). This intense mineralization hosted within a pre-mineral intrusive breccia host rock suggests that a fluid-rich source intrusion may be intersected through further drilling at depth, and indicates the potential for a deeper bulk underground target that may lie beneath the current drilling area. Further drilling is planned to test for the potential of a deep-rooted porphyry system.
Mineralization at TAM forms a northwest trending corridor, occupying and area 750m long x 500m wide extending from surface to a depth of over 1,200m. The TAM target lies open is several directions:
The 2021 proposed drilling program focuses on three main factors:
