VANCOUVER, British Columbia, Nov. 23, 2017 (GLOBE NEWSWIRE) -- Core Gold Inc. ("Core Gold" or the "Company") (TSX-V:CGLD)(OTCQX:CGLDF) is pleased to provide an update on gold production. Core Gold has produced 8,507 ounces of gold year to date October 31, 2017 including 2,215 ounces in October 2017 solely from the new Dynasty Goldfield mining unit. The Dynasty Goldfield is the first new mining unit put into production by Core Gold Inc.

Production Update

Since changing management in September 2016, the Company has focused its mining activities at the Dynasty Goldfield project. Mining activities at Dynasty Goldfield began in January 2017 and since then the Company has successfully ramped up production from Q1 to Q3 2017. Although a much heavier than usual El Niño-related rainfall in Q2 hindered ramp up, the Company successfully stabilized production in Q3 2017, reaching a peak monthly production rate of approximately 1,800 oz of gold per month. In the month of October 2017, production reached a record level of approximately 2,215 oz of gold, the highest monthly level since commencement of production.

Based upon the current Portovelo plant (formerly known as the Zaruma plant) capacity of 750 tons per day, gold production from the Dynasty Goldfield mining unit alone may be able to sustain an annualized rate of approximately 22,000 to 26,000 ounces.*

Period Gold Production (oz Au)
Q1 2017 1,170
Q2 2017 898
Q3 2017 4,233 (peak monthly production at 1,800 oz)
Q4 2017 (October 2017 only) 2,215
Total year to date (10 months ended) 8,516

Keith Piggott, President and Chief Executive Officer of Core Gold, commented: "We are very pleased to announce that we have ramped up gold production and that we have put an entirely new mining unit into production at Dynasty Goldfield. The Dynasty Goldfield mining unit is an asset that we took into production within four months of assuming control of Core Gold and we are very excited by its operational results. We will strive to further improve our production figures in the upcoming fiscal year and to start executing on our high impact exploration plans throughout the Dynasty District shortly."

All of the Company's material from Dynasty Goldfield is being trucked to the Company's wholly owned Portovelo processing plant for processing and sale. Core Gold management wholly refurbished the crushing circuit at the Portovelo processing plant and has plans in place to increase plant capacity back up to its nameplate 2,000 tpd capacity with a USD $4M capital expenditure program. The main thrust of this plan will include refurbishment of the milling circuit where currently only one 1,000 tpd mill is operational and increasing carbon-in-pulp tank capacity.

The Dynasty Goldfield Project

Per the 43-101 Technical Report entitled "Dynasty Goldfield Project – Celica, Loja Province, Ecuador" dated October 22, 2014 (which can be found on both the Core Gold website and at (the "Technical Report"), with over 1.0 million ounces of gold in the Measured and Indicated mineral resource categories and another 1.1 million ounces of gold in the inferred category, the Dynasty Goldfield Project has the potential to significantly drive the Company's gold production going forward.

The Dynasty Goldfield Project is fully qualified and permitted under Ecuador's small-scale mining regime and subject to a fixed 3% royalty with no windfall tax. The small-scale mining regime allows open pit activities with an exploitation volume of up to 1,000 tonnes a day per concession, which would allow up to a total of 3,000 tonnes per day production from the three contiguous concessions that contain the Dynasty Goldfield's gold resources.

Mineral resource estimate for the Dynasty Goldfield Project is as follows (please refer to the Technical Report for further details):

Category Tonnes
Gold grade
Silver grade
Measured 2,909,000 4.7 437,000 38.1 3,567,000
Indicated 3,958,000 4.6 585,000 38.8 4,936,000
Total M&I 6,867,000 4.6 1,022,000 38.5 8,504,000
Inferred 7,825,000 4.4 1,118,000 39.4 9,901,000

Note: A cut-off grade of 2.0 g/t was used to derive the mineral resource estimate.

Since commencement of production at Dynasty Goldfield, the head grade of mined material delivered to the Zaruma processing plant has averaged 3.2 grams/ton gold, which when accounting for mining dilution is consistent with the resource grade as defined in the Technical Report despite not having established reserves. Further, since commencement of production along 6 previously identified veins in the Cerro Verde Zone of the project, the Company is pleased to announce that a further 3 veins have been discovered and mined suggesting further potential upside to the project's already significant resources and development potential. 

The Dynasty Goldfield Project covers an area of approximately 21,909 hectares within the Dynasty Copper-Gold Belt. The Dynasty Goldfield Project includes the Papayal Project and Cerro Verde quartz vein swarms and stockworks, where drilling has confirmed the presence to depth of high-grade gold and silver mineralization.

To date, 26,700 metres of drilling have been completed on the Dynasty Goldfield concessions, to depths of approximately 200 metres.

Mining operations at Dynasty Goldfield are directed by Core Gold management and undertaken by Green Oil S.A, an Ecuadorian contractor. Under the terms of the contractor agreement with Green Oil S.A, the contractor funded initial mining capital expenditures at Dynasty Goldfield and funds ongoing working capital requirements in return for 40% of refined gold sales and 10% of refined silver sales from the concessions defined under the agreement. For further details on the agreement with Green Oil S.A please refer to the Company's news release from April 27th, 2016.

Cautionary Note regarding Production without Mineral Reserves

The decision to commence production at the Dynasty Goldfield Project and the Company's ongoing mining operations as referenced herein (the "Production Decision and Operations") are based on economic models prepared by the Company in conjunction with management's knowledge of the property and the existing estimate of measured, indicated and inferred mineral resources on the property. The Production Decision and Operations are not based on a preliminary economic assessment, a pre-feasibility study or a feasibility study of mineral reserves demonstrating economic and technical viability. Accordingly, there is increased uncertainty and economic and technical risks of failure associated with the Production Decision and Operations, in particular: the risk that mineral grades will be lower than expected; the risk that additional construction or ongoing mining operations are more difficult or more expensive than expected; and production and economic variables may vary considerably, due to the absence of a detailed economic and technical analysis in accordance with NI 43-101.
