PEA on Regional Gold Processing Plant in ColombiaOneCap Announces Results of a Preliminary Economic Assessment for a 300 t/d Regional Gold Processing Plant in Colombia MONTREAL, April 16, 2018 (GLOBE NEWSWIRE) -- OneCap Investment Corporation ("OneCap or the Corporation") (TSX VENTURE:OIC) is pleased to announce the receipt of a technical report regarding a Preliminary Economic Assessment (PEA) of a 300 tonnes per day (t/d) regional gold processing plant in the Bolivar South province, Colombia (the Mill Project). In 2017, OneCap has initiated a regional sampling program of the artisanal production sites in South Bolivar in order to evaluate the gold potential within 40 kilometres of the Corporations Las Marias gold property (the Area) and identify concessions for possible acquisitions. The positive results from this survey, conducted on sites not owned by the Corporation, (December 5, 2017 news release) led to the engagement in January 2018 of Bumigeme Inc. (Bumigeme), an engineering firm specialized in metallurgy and plant design in Montreal, to conduct a study to evaluate the feasibility of operating a 300 t/d (105,000 tonnes per year (t/y)) regional gold milling and processing facility in the Bolivar South province. The processing facility would treat the mineralized material from the artisanal mining sites in the Area where 60 producing sites have been surveyed and revealed an average daily production of 413 t/d at 16.17 g/t Au and 293.52 g/t Ag; including 301 t/d at 21.0 g/t Au and 380.36 g/t Ag at 5 g/t Au cut-off. Metallurgical testwork, supervised by Bumigeme, were performed at Actlabs in Thunder Bay on composite samples representing a weighted average of the daily production of the 60 artisanal producing sites. The results of those tests were used to design a flowsheet for a gravity followed by cyanidation processing plant and to calculate its operation cost. The highlights of the technical report entitled Preliminary Economic Assessment of the regional gold processing plant, 300t/d mill project, Department of Bolivar (South), Colombia are: a.Results indicate gold recovery of 90% using a process flowsheet consisting of gravity separation followed bycyanidation; b.Mineralized material from different artisanal miners to be trucked to the plant, weighted, assayed and stockpiledindividually; c.Dry tailing will be produced and stockpiled; d.The capital expenditure for the Mill Project is estimated at US$10.9 million; e.The operation cost, including general and administration, is estimated at US$67 per tonne of mineralized materialmilled; f.The financial analysis performed shows an after tax net present value of US$91.6 million at 10% discount rate. The after taxinternal rate of return for the base case is 167.1% based on a price of gold of US$1,200 per ounce, a gold grade of 20.7 g/t,life of operation of 15 years with first year at 52,500 t/y, second year at 78,750 t/y and 105,000 t/y thereafter. Outlook for Q2-2018 On the Las Marias project, results from work performed until now are being carefully analyzed by the Corporation in order to design the next exploration phase, including additional trenching and rock geochemical survey. A diamond drill program will be considered subject to positive results from the trenching and geochemical survey and securing additional funding. On the regional gold processing plant, the results of the technical report show a viable project. The Corporation will first evaluate the financial markets appetite for this kind of project and then define the technical, financial and regulatory parameters to implement the Mill Project. Before proceeding with the Mill Project, the Corporation should obtain the TSX Venture Exchange (the Exchange) approval that could trigger a Change of Business (COB) as defined by Policy 5.2 of the Exchange. The securities of OneCap could be subject to a trading halt until the Corporation satisfies Exchanges requirements for a COB and receives shareholders approval. Qualified Persons This news release has been reviewed and approved by Daniel Goffaux, P.Eng., a Qualified Person as defined by National Instrument 43-101. The PEA has been prepared by Bumigeme and Daniel Goffaux (D.G. Mine Consultant Inc.). The qualified persons at Bumigeme responsible for the preparation of this report are independent of OneCap. Mr. Goffaux is not independent of the Corporation as he acts as principal technical advisor for the Corporation. Cautionary statement NI 43-101 The PEA was prepared in accordance with National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101"). Readers are cautioned that the PEA is preliminary in nature and is based on samples from artisanal mining operations of small mineralized veins, highly irregular in size and grade. The sample results are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the Mill Project will be realized.
