Colibri Resource Corporation announced that a total of 1,122 meters has been drilled in 10 diamond drill holes at its El Pilar Gold & Silver Project in Sonora Mexico. Colibri holds 49% interest of the El Pilar along side its partner Tocvan Ventures, which holds a 51% ownership in this advanced stage exploration project. Highlights: 1,122 metres drilled in 10 diamond holes a Pilar Gold & Silver Project Samples for first three drill holes have been sent to laboratory for analysis.
Initial review of drill core indicates key structures and favourable rock characterization have been encountered. Advancing plans for up to 50,000 tonne bulk sample/pilot facility. The core program was designed and managed by Tocvan with the aim to infill and step out on known mineralization corridors.
The information collected will assist in building a robust geological model set to go into a maiden resource estimate and ultimately a Preliminary Economic Assessment for Pilar's Main Zone. Samples for the first three drillholes (JES-25-103 to JES-25-105) have been delivered to the local ALS Prep Laboratory in Hermosillo, Sonora. Tocvan has also reported that core reviewed from this drill program displays indications of key lithologies and structures known to host and control gold & silver mineralization at Pilar.
A summary of these mineralization types is summarized below in Plate 1. The Company cautions these are visual indications; assay results are pending to verify the grade of mineralization and width. Plate 1. Different alteration and lithology styles related to mineralization at Pilar as seen in the recent core program. E. Silicified breccia with intense chlorite and pyrite and minor chalcopyrite, JES-25-107, 55m depth.
Intense fractured silicified breccia with intensity hematite and late calcite veins, JES-25-105, 85m depth. The Company cautions these is visual indications; assay results are ongoing to verify the grade of mineralisation and width. The Pilar gold-silver property has returned some of the region's best drill results.
Coupled with encouraging gold and silver recovery results from metallurgical test work, Pilar is primed to be a potential near-term producer. The project is interpreted as a structurally controlled low-sulphidation epithermal system hosted in andesite rock. Bulk sample only included coarse fraction of material;.
Fine fraction indicates rapid recovery with agitated leach: Agitated bottle roll test returned rapid and high recovery results: 80-per-cent recovery of gold and 94-per-cent recovery of silver after rapid 24-hour retention time. Additional metallurgical studies: Gravity recovery with agitated leach results of five composite samples returned: 95- to 99-per-cent recovery ofgold;. 73- to 97-per-cent recovery ofsilver; Includes the recovery of 99% Au and 73% Ag from drill core composite at 120metre depth.
