Orvana Identifies 17 New High Probability Gold Targets at th
TORONTO, Sept. 14, 2020 /PRNewswire/ - Orvana Minerals Corp. (TSX: ORV) (the "Company" or "Orvana") is providing an update on its exploration program at the Taguas mining property ("Taguas" or the "Property") located in the San Juan province, Argentina. As a result of the completion of a recent artificial intelligence assisted data analysis, Orvana has identified a total of 17 new high probability gold targets at Taguas, consisting of 9 new areas and 8 extended areas of previous known mineralization. All of the newly identified targets are based on a 96% level of similarity to the known gold mineralization. These results suggest that there is an enhanced probability of increasing the potential of the Property's oxides and sulphides resources. The potential of the new gold targets remains subject to additional fieldwork to be conducted the next summer season in Argentina. If COVID-19 restrictions allow, the field work campaign will include opening new access points, surface mapping and soil and rock sampling.
Orvana retained Windfall Geotek ("Windfall"), a TSXV-listed company, to analyze existing Taguas data in connection with the development of the gold exploration targets at Taguas. Utilizing its Computer Aided Resources Detection System ("CARDS"), Windfall processed the geophysical, geochemical, and geological data provided by Orvana to analyze the patterns hidden in the large amount of existing data, which consisted of a drill hole database containing 220 drill holes, a surface samples database containing 854 samples, and Magnetic (TMI) and Radiometric (K, Th, U & TC) data at 10m resolution (417,716 datapoints). The public SRTM (Shuttle Radar Topography Mission) data was also used to characterize the topography.
Mr. Raúl Álvarez, Head of Exploration of Orvana, stated: "We are excited about the identification of the 17 new gold targets, which, if confirmed through additional fieldwork, will materially increase the potential upside of Taguas. Field work planned for the following months will provide key information to optimize the definition of the next drilling campaign". Mr. Álvarez added that "The Company is taking advantage of new technologies to optimize the exploration programs and reduce costs, while advancing the project despite COVID-19 restrictions".
The new gold exploration targets that have been identified, are represented as red shapes in Figure 1.
Background of the Taguas Mining Property
On May 14, 2019, Orvana entered into a purchase agreement with Compañía Minera Taguas S.A. pursuant to which Orvana agreed to acquire the Taguas property located in the Province of San Juan, Argentina. Closing of the transaction is subject to applicable local mining rights registrations and the final acceptance of the Toronto Stock Exchange. The process to complete the acquisition and registration of the Taguas Project in Argentina has been delayed due to COVID-19 travel restrictions and national lockdown measures. The Company is not in a position to determine a timeline to complete the registration of the acquisition of the Taguas Project in Argentina until the COVID-19 restrictions are lifted.
Taguas is located at the northern end of the Tertiary-age Valle del Cura volcanic belt in Argentina (Figure 2) and on the eastern flank of the El Indio metallogenic belt1. The Valle Del Cura belt has a similar basement, comparable volcanism ages and alteration as the volcanism on the Chilean side2 and constitutes an extension of the El Indio belt into Argentina.
Taguas consists of 15 mining concessions over an area of 3,273.87 ha. The Property is located in the Province of San Juan, Argentina, on the eastern flank of the Andes, between 3,500 m to 4,300 m above sea level. The Property is host to a high-sulfidation epithermal gold-silver system hosted in altered tertiary age rhyolite volcaniclastic rocks. Supergene-oxidized gold-silver mineralization occurs on the south half of the Property.
On July 9, 2019 the Company filed a Preliminary Economic Assessment Report for the Taguas property (the "PEA"). A copy of the PEA may be obtained on the Company's profile at www.sedar.com. The PEA refers only to the oxidized gold-silver mineralization occurring near surface known at the date of the report, consisting of sub-vertical, northeast striking mineralized structures in an envelope of lower grade mineralization. The high-grade zones consist of relatively continuous mineralization with gold grades ranging from 0.2 g/t Au to over 4.0 g/t Au and 10 g/t Ag to over 50 g/t Ag. Oxidation extends from surface to approximately 100m – 200m below surface. The PEA utilized the following inferred mineral resource:
Estimate of Inferred Mineral Resource reported at 0.25 g/t AuEq Cut-off
COG g/t AuEq
1. Mineral Resource estimate prepared by Mr. R. Simpson, P.Geo., of GeoSim Services Inc. with an effective date of 14 May 2019. Mineral Resources are classified using the 2014 CIM Definition Standards.
2. Gold equivalent (AuEq g/t) calculations were based on assumed metal prices of $1300/oz Au, and $17/oz Ag, recoveries of 87% Au and 52% Ag. AuEq = Au(g/t) + Ag(g/t) *0.0078
3. An optimized pit shell was generated using the following assumptions: metal prices/recoveries in Note 2 above; a 45° pit slope; mining costs of $2.00 per tonne, processing costs of $5.20 per tonne, and general & administrative charges of $1.50 per tonne. All amounts are expressed in US dollars.
4. Totals may not sum due to rounding.
5. Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability.
Mineral resources that are not mineral reserves do not have demonstrated economic viability. The PEA is preliminary in nature and includes inferred mineral resources that 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 results of the PEA will be realized. The financial analysis in the PEA does not include the 2.5% royalty associated with the acquisition of the Property by Orvana. The PEA study is conceptual in nature and the PEA mine plan is based on 100% inferred resources. The projections, forecasts and estimates presented in the PEA constitute forward-looking statements and readers are urged not to place undue reliance on such forward-looking statements. Additional cautionary and forward-looking statement information is detailed at the end of this news release.
