Oroco Resource Corp. files amended 43-101 report.

February 4, 2008

VANCOUVER, Feb. 4 /CNW/ – On Feb. 4th Oroco Resource Corp. (the “Company” or “Oroco”) filed an amended technical report entitled “Report on Phase 1 Exploration, Cerro Prieto PB-Zn-Au-Ag-Mo Project, Magdelena de Kino Area, Sonora State, Mexico” dated December 14, 2007 (the “Amended Report”) on SEDAR regarding its Cerro Prieto property (the “Property”).

The Amended Report, which has been prepared pursuant to National Instrument 43-101, contains material amendments to the technical report filed by the Company in connection with its preliminary prospectus on October 26, 2007. The Amended Report discloses historical preliminary estimates for the Property which were reported by Morgain Minerals Inc. (“Morgain”), a TSX Venture Exchange listed company, in its 1998 Annual Report which was filed on SEDAR on May 19, 1999. These historical estimates of 6.1 million tons with an average gold equivalent grade (as calculated at that time) of 4.85 g/t or 7.0 million tons with an average gold equivalent of 4.4 g/t were reported to have been based upon assay results of a 23 hole reverse circulation drill program conducted by Morgain and samples taken from underground crosscuts on the Property. Oroco cautions that the Company does not have a technical report available to it which includes these historical estimates. Consequently, the location of the drill collars or intercepts, the methodology used in the calculations of the average individual grades for each block and the methodology and assumptions and parameters used in the preparation of the historical estimates are not known. It is presumed that the historical estimates were calculated using only geometrical parameters and assays taken at widely spaced intervals. It does not appear that geostatistical information or economic factors were used to back up the valuations.

However, it is the opinion of the author of the Report (the “Author”) that the exploration results available to Morgain would have provided sufficient information to calculate the reported preliminary estimates and that, subject to categorization of the reserve or resource, based upon the historical information available and the Author’s own sampling results, these historical estimates are reasonable. Confirmation drilling proposed by Oroco will test their reliability.

Oroco further advises that Morgain’s historical estimates, which were reported as “preliminary reserve estimates”, were prepared prior to the implementation of the Standards of National Instrument 43-101 and that under current definitions of “mineral resources” and “mineral reserves” as stated in sections 1.2 and 1.3 of National Instrument 43-101 or in the CIM Standards on mineral resources and reserves, there is no category of “preliminary reserve estimate”. However, the Author is of the opinion that under current definitions of “mineral resources” and “mineral reserves” under National Instrument 43-101 and the CIM Standards, the Morgain estimates would correlate to the Inferred Resource category.

There is no more recent estimate or more recent data available, that the Company is aware of, other than sampling data obtained by the Author. A qualified person has not done sufficient work to classify the historical estimates as a current mineral resource. Oroco is not treating the historical estimates as current estimates and the historical estimates should not be relied upon as current estimates.

Duncan Bain P.Geo. is the qualified person responsible for the disclosure about the technical information reported in this news release. Mr. Bain has reviewed and approved the technical disclosure in this news release. Further information on the Company is available at www.sedar.com

These historical resource estimate models are based upon historical resource estimates prepared by John Thornton in 2011. While, in the opinion of Dane A. Bridge, author of the revised NI 43-101 standard technical report, Geology, Mineralization and Exploration of the Santo Tomas Cu-(Mo-Au-Ag) Porphyry Deposit, Sinaloa, Mexico dated April 21, 2020 (the “Report”), reliable estimation practices were used, in order to upgrade or verify the historical estimations, resampling and assay of historical drill samples, twinning of historical drill holes, and a new program of regularly spaced drilling is required. No qualified person has undertaken sufficient work to classify the current mineral resources or mineral reserves upon which these models are based and the Company is not treating the estimates as current estimates of the mineral resources. The Company gives no assurance that either these models or the historical resource estimates upon which they are based are accurate, and does not undertake any obligation to update the models or to release publicly any update or revisions of the resource estimates except as required by applicable securities law. The reader is cautioned not to rely upon these models or the historical resource estimates upon which they are based.
