Gold-Silver Geochemical Anomalies Defined by Soil Sampling Program at El Zanjon, Argentina
VANCOUVER, British Columbia, April 28, 2020 (GLOBE NEWSWIRE) — Rugby Mining Limited (“Rugby” or the “Company”) (TSX-V: RUG) is pleased to report on the results of a soil sampling program recently completed on the El Zanjon gold-silver project in Santa Cruz province, Argentina.
The program was initiated by Rugby as a follow-up to ground magnetic surveys which had outlined prospective structures for hosting epithermal gold silver mineralization characteristic of the Deseado Massif. The favourable host rocks underlie recent sediments up to 100 meters (“m”) thick.HighlightsThe geochemical program comprised some 108 surface samples collected at 320 m spaced intervals over 35-line kilometres.Samples were assayed for 61 multi-elements using ultra-sensitive Ionic Leach by ALS (Vancouver). This methodology is used to identify metal zonation within and haloes surrounding mineralization.Gold values range from 0.02 to 0.96ppb and silver values range from 11 to 30.1ppb (Figures 2 & 3).Ten zones of anomalous gold-silver geochemistry were defined (Figure 4) ranging from 320 m to 2,800 m in length.A number of these anomalies have coincident lower pH readings (Figure 5) suggesting an acidic environment which can indicate oxidation from sulfides at depth, an association common to other epithermal projects in Patagonia.Additional in-fill geochemical sampling is recommended.Project LocationEl Zanjon covers approximately 600 square kilometres near world class mines at Cerro Negro (Newmont-Goldcorp), Cerro Vanguardia (AngloGold Ashanti) and Cerro Moro (Yamana) (Figure 1).
