VANCOUVER, BRITISH COLUMBIA–(Marketwired – Sept. 22, 2015) – Columbus Gold Corporation (TSX VENTURE:CGT)(OTCQX:CBGDF) announces results of its summer RC drilling program at its 100% controlled Eastside gold project in Nevada.
The drill program was successful in achieving the objective of validating that oxide gold mineralization encountered in surface sampling grading up to 16 g/t gold, extends at depth in the form of zones of lower grade “cloud” gold mineralization that overlays zones of better-grade. The current drilling has also revealed that the zones of better-grade gold mineralization are unusually thick and much larger than previously interpreted and that they are open in all directions. In addition, many of the holes drilled into the better-grade zones bottomed in significant gold values.
Robert Giustra, Chairman and CEO of Columbus Gold, commented: “These drill results indicate that gold mineralization at Eastside is considerably more widespread than previously understood. This bodes well for a project that is located in an area with outstanding infrastructure and for which preliminary metallurgical testing suggests good recoveries.”
A total of 12,298 meters (40,347 feet) was drilled in 51 holes, widely spaced over a mineralized area of at least 1,050 X 550 meters. Of the 51 holes, 46 completed or hit the intended target and of those 46 holes, all intersected gold mineralization, and 38 of them return significant gold results. In addition 17 holes bottomed in gold. Following are significant intercepts:
|ES-80||152.4 m of 0.71 g/t gold, including 28.9 m of 2.16 g/t and 3 m of 10.88 g/t gold|
|ES-83||109 m of 0.69 g/t gold, including 10.8 m of 2.30 g/t and 18.2 m of 1.32 g/t gold and an additional 10.6 m of 1.49 g/t gold|
|ES-84||63.6 m of 1.20 g/t gold, including 4.5 m of 2.06 g/t, 1.5 m of 2.43 g/t gold, 7.6 m of 4.25 g/t gold and 1.5 m of 2.65 g/t gold|
|ES-86||24.4 m of 2.70 g/t gold, including 3 m of 17.3 g/t gold|
|ES-39||27.4 m of 2.54 g/t gold and 36.5 g/t silver, including 3 m of 19.61 g/t gold|
|ES-40||32.0 m of 1.248 g/t gold and 3 m of 203 g/t silver|
|ES-45||59.4 m of 0.92 g/t gold, including 25.9 m of 1.62 g/t gold|
|ES-46||59.4 m of 0.58 g/t gold, including 16.8 m of 1.03 g/t gold|
|ES-58||19.8 m of 1.00 g/t gold and 4.6 m of 1.01 g/t gold|
|ES-61||21.3 m of 0.89 g/t gold, including 3 m of 2.07 g/t gold|
|ES-67||22.9 m of 1.37 g/t gold, including 7.6 m of 2.95 g/t gold|
|ES-71||35.1 m of 0.90 g/t gold, including 12.2 m of 2.61 g/t and 7.6 m of 3.53 g/t gold and an additional 19.8 m of 0.96 g/t gold, including 3 m of 4.57 g/t gold|
|ES-78||7.6 m of 3.19 g/t gold|
|ES-81||56.4 m of 0.62 g/t gold and 11 g/t silver, including 13.7 m of 1.13 g/t gold|

Columbus is very encouraged by the upside potential at Eastside. Planning for the next phase of drilling is in progress and will include deep core drilling to further examine gold mineralization at depth. The deeper drilling to date indicates that gold mineralization could underlay the entire drilled area and the thickness of the gold intercepts in these deeper holes makes Eastside an attractive target for large volumes of gold mineralization.

Eastside gold mineralization occurs in a discrete package of overlapping, rhyolite flow dome complexes which were emplaced and/or erupted 7.2 million years ago. These flow dome complexes are confined to an outcrop belt about two miles wide and seven miles long which is completely enclosed in Columbus Gold’s claim block. Detailed mapping and sampling of the entire claim block by Columbus geologists has yielded numerous additional targets outside of the area of the current drilling.
The project has outstanding infrastructure for mining and processing; is 32 km (20 mi) west of Tonopah, Nevada, and lies 9.7 km (6 mi) north of paved highway US 95, the main road route from Las Vegas to Reno. A good gravel road from the highway, along with a major power transmission line both pass through the claim block. The current drilling area is on the east flank of the Monte Cristo Range and a portion of the claim block extends well into the adjacent flats, which would provide excellent operating sites. The valley is known to have shallow water available in the same aquifer, which provided water for milling the Tonopah ores in the early 1900s. The area is high desert with sparse vegetation, and year-round drilling is possible.
Gold and silver assays for Phase IV drilling were performed by American Assay Labs in Sparks, Nevada. American inserts blinds and standards in the drill-hole assay string-generally 7% of all assays performed are of standards or blinds. For Phase IV drilling, gold analyses are by fire assay with atomic absorption finish. Silver assays are by fire assay with gravimetric finish. In addition, Columbus Gold also inserts blank samples and also standard samples of known gold and silver assay values in the drill assay string for quality control. Additional check sampling is ongoing and, if material differences occur, those will be reported. All Phase IV holes were surveyed downhole by IDS.
