Casa Minerals Inc. (TSX-V: CASA, FRANKFURT: 0CM, OTC: CASXF) (the “Company” or “Casa”) in September 2018 completed a 223 km airborne VTEM™ and magnetic survey of its Pitman property located east of Terrace, B. C. Casa is pleased to announce that the survey data displays a large conductive (up to 25 ohm-m) near-surface mass in parts of the property that were previously identified by geological mapping, surface sampling and geochemical analyses as potentially valuable gold, silver and base metal occurrences. The conductivity range of this unit, 0.44 to 25 ohm-metres, is consistent with that of sulphide mineral occurrences. The surface expression of the geophysical anomaly is approximately 2.3km x 1.4km and includes the areas of the Golden Dragon and Dragon Tale discoveries that were announced earlier (New Releases Oct. 16 and Dec. 12, 2018).
The Golden Dragon was discovered in 2018 (News Release 16/10/18) and is situated close to the “Lucky Zone”, another discovery that has yet to be investigated, and the historic Paddy Mac Gold prospect. The Golden Dragon includes numerous gold and silver veins that returned values as high as 574 g/t gold plus 109 g/t silver, 0.1% copper, 1.56% lead and 0.23% zinc over 0.6m and 268.86 g/t gold, 127 g/t silver, 0.2% copper, 2.95% lead and 0.04% zinc over 1m. The Golden Dragon complex quartz veining system is the project’s advanced exploration target.
The Dragon Tale zinc-silver-copper mineralization, another 2018 discovery, is exposed along a logging road (News Release 12/12/18). Samples returned assays as high as 231 g/t silver, 3.18% copper (not previously reported) and 11.98% zinc in a zone exposed for 320 metres along a logging road and nearby outcroppings. The follow-up airborne VTEM™ and magnetic survey showed strong conductivity and moderate magnetic susceptibility, consistent with mineralization in a sedimentary system, that extends easterly to the property boundary. Casa’s data indicates that the host formation is a weakly metamorphosed mixed black shale and fine-grained sandstone unit, believed to be of Mid to Upper Jurassic age, that, in the opinion of provincial geologists who mapped the formation in the Pitman area in 2006, may correspond to rocks that occur in and near the historic Eskay Creek Mine. Mr. Shirvani, President and CEO of Casa, notes that the Dragon Tale is easily accessed by logging road and will be a high priority for drill testing.
The WoMo prospect comprises strong sulphide mineralization in a large area of porphyry-type alteration adjoining a granitic intrusion. Government geologists noted that the mineral zone resembled “…a classic porphyry system located at the margin of the Carpenter Creek pluton” with gold-silver-base metal enrichments. Metal values were confirmed in 2010 by company personnel who reported numerous samples with assays in excess of 1% copper, 1% lead, 1% zinc and as high as 3,225 and 3,929 ppb gold. The airborne geophysical survey mapped strong resistivity and strong magnetic intensity in the WoMo area, giving it added potential for significant discoveries.
The VTEM™ apparent 3D resistivity and magnetic data, and geochemical and prospecting discoveries will be the basis for selecting Golden Dragon and Dragon Tale drilling targets.
