Core Gold Inc. (TSX-V: CGLD) (OTCQX: CGLDF) is pleased to announce that it has completed a 1,927 meter drilling campaign at its wholly owned Linderos property in Ecuador.

Results of this drilling campaign show the following select intervals:

• 5.94 m @ 10.78 g/t Au included within 28.80 m @ 2.56 g/t Au
• 7.80 m @ 5.25 g/t Au included within 19.60 m @ 2.27 g/t Au

These initial results provide evidence that the two main gold bearing mineralized structures (target 1 and 2) discovered through Core Gold’s preliminary surface trenching program in 2017 extend at depth.

The gold mineralization thus far identified is associated with sulphide veins cutting intensely quartz-sericite-pyrite altered felsic igneous rocks. Mineralization is contained within a NW trending fault (shear zone) related brecciated structures adding together up to 25 m wide and are oxidized to a depth of approximately 30 meters.

Late, gold bearing sulphide veins are hosted in discrete shoots within the NW trending fault zone. The controls on the localization of the high-grade gold mineralization have yet to be determined.

Moving forward, detailed mapping and structural analysis will lead to a better understanding of the controls of the gold mineralization and the development of a predictive model.

Drilling to date has tested a relatively small section of the 1km by 150 m zone of outcropping gold mineralization adjacent to, and along strike from the discovery outcrop (21m @18.51 g/t gold). The eastern half of the 1km strike extent, highlighted by trench samples of 32 m @ 3.02 g/t Au and 4.40 m @ 11.11 g/t Au (see press release, Feb. 22, 2018), has yet to be drill tested and will be targeted in future drill programs. 

To date, 11 exploration diamond drill holes from 5 sites have been performed all with azimuth ranging from 33° to 276°, and 6 drill holes with an azimuth of 213°. Inclined depths range from 99 m to 280 m, with inclination angles from -45° to -75°. A Hydro-Core 2000 portable drill rig owned by the Company was used.

QA & QC procedures and protocols have been implemented to secure accuracy for this drilling campaign. Core samples have been shipped to Inspectorate Lab in Peru, an international qualified laboratory. Details of the drill results are set forth below. Note that true widths are not stated.

The Linderos Project

The Linderos project is an exploration property located in the Macara County, Loja province, southern Ecuador. It is composed of four contiguous concessions totaling 14,317 hectares, located approximately 45 Km southwest of the Company’s Dynasty Goldfield project. The Linderos project comprises gold-copper porphyry system style mineralization.

Within the Linderos project, the hydrothermal alterations zone covers an area of about 1.5 Km2. The porphyry is emplaced in island arc Cretaceous volcanic rocks of the Celica Formation and it is structurally controlled by a shear zone with a northwest-southeast strike. This structure hosts economic porphyry related gold mineralization associated with oxidized mesothermal – epithermal mineralized structures.

The porphyry system is formed by an initial intrusion of dioritic composition, which hosts late mineralized intrusive phases of quartz-diorite, tonalite and rhyolite-dacite composition. The hydrothermal alterations zone is characterized by the occurrence of a potassic core surrounded by phyllic and propylitic alteration halos. Mineralization is mainly related to copper and molybdenum observed as disseminated chalcopyrite and molybdenite in veinlets, mainly hosted in the quartz-diorite. Locally, an oxidation zone has been observed with occurrence of malachite and chrysocolla.

About Core Gold

The Company is a Canadian based mining company involved in the mining, exploration and development of mineral properties in Ecuador. The Company is currently focused on gold production at its wholly-owned Dynasty Goldfield project and continued development at its legacy Zaruma mine. Mineral is treated at the Company’s wholly-owned Portovelo treatment plant close to the Zaruma mine operations. The Company also owns other significant gold exploration projects including the Linderos and Copper Duke area in southern Ecuador all of which are on the main Peruvian Andean gold-copper belt extending into Ecuador.
