Centurion Completes Successful Field Program at Ana Sofia Gypsum Project, Argentina
Centurion Minerals Ltd. has completed a successful field program at the Ana Sofia agricultural gypsum project in Santiago Del Estero, Argentina. The primary objective of the program was to confirm the extent of near surface gypsum layers at the Ana Sofia 2 mining concession and was extended onto the company’s adjacent exploration permit area.
The program consisted of systematic grid-based test pitting and mechanical trenching on a total of 20 sites over an approximate area of 50 hectares (ha). The test sites comprised 15 new test pit (trenches) along with the excavation and sampling of five locations within historical quarries. All but two of the test sites identified at least one high quality gypsum layer ranging in thickness from 0.4 meters (m) to 2.1m.
The 20 test sites represented a total of 154 vertical meters of excavation individually ranging in depth from 3.5m to 15.0m and averaging approximately 7.7m. For the 18 test sites where high purity gypsum was encountered, the average depth from surface to the top of the gypsum layer was approximately 3.7m.
The target stratigraphy exposed at each test site, comprising discreet gypsum layers hosted primarily in green clays, was sampled by collecting vertical chip/channel samples respecting lithologic boundaries. The samples are being shipped to ALS Laboratories for analysis.
The layout of the test pit trenches and historical quarry sections sampled approximates a 200m x 300m grid pattern with some infill testing. The spacing of the test pits is deemed to be appropriate given the consistency and continuity of the gypsum that can be observed along the western side of the resource area where an almost uninterrupted exposure of gypsum can be followed for approximately 800m along a north northeast trend.
The data generated by this program will be utilized to complete a geological model and resource estimation work, the results of which will be released in due course.
