- Recharge Resources provides update on redonda copper project with up to 96.9% recovery with recent drill intercepts of up to 142.6 meters .279% copper .0281 molybdenum.
Recharge Resources Ltd. has provided an exploration update from its 2,746.46-hectare Redonda copper-molybdenum project, located within the Vancouver mining division of British Columbia.
Recent drilling at the project returned up to 142.6 metres (467.8 feet) of 0.279 per cent copper and 0.0281 per cent molybdenum.
The company has received excellent metallurgical test results by Process Mineralogical Consulting Ltd. (PMC Labs) from the Redonda copper, molybdenum and rhenium drill program.
The main copper-bearing and molybdenum-bearing phases in the master composite are chalcopyrite and molybdenite, respectively. This material reports 0.33 weight per cent copper, 5.74 weight per cent iron and 0.33 weight per cent molybdenum, accompanied by 2.3 parts per million silver.
Flotation testwork suggests that the initial samples and exploratory testwork are successful in producing copper recoveries ranging from 94.7 per cent to 96.9 per cent and molybdenum recoveries ranging from 92.2 per cent to 95.6 per cent after five stages of rougher flotation tests.
The metallurgical program was coupled with detailed mineralogical investigation on the material provided, aiming at identifying the main mineral phases that make up the ore. This was achieved by carrying out size-by-size automated SEM-based (scanning electron microscopy) mineralogical characterization (AutoSEM), providing quantitative information on the mineral phases and their abundance (modal composition), particle and grain size distributions, mineral associations, and liberation characteristics. The acquired mineralogical information was then employed to support the design of the metallurgical tests and interpret the results.
The project was carried out in a two-stage approach. The first stage was based on the size-by-size mineralogical characterization of the ore, followed by metallurgical testing through the analysis of grinding properties and flotation trials.
A Bond Work Index (BWI) of 15.17 kilowatt-hours per tonne for the master composite indicates that the material falls within the moderate hardness range. This value is comparable with typical BWI values for copper and copper-molybdenum ores, which generally range between 10 and 20 kilowatt-hours per tonne.
To achieve a P80 of 75 micrometres, the target grinding size for optimal liberation (as established in the size-by-size mineralogical characterization results), a stage-grind calibration test was conducted on the master composite. The test results indicated that 108 minutes of grinding would be required to reach a P80 of 74 micrometres.

The currently known highest-grade copper-molybdenum zone and associated breccias extend over a defined northerly horizontal length of over 600 metres, a width of at least 500 metres and a vertical extent of 300 metres. This higher-grade, potassic-altered centre of mineralization is composed of variable density of dark mafic-rich fragments. Higher grades are clearly related to abundance of dark fragments in vugs and heavy chalcopyrite/molybdenite and pyrrhotite replacement.
However, some high-grade copper/molybdenum sulphide is also associated with the density of quartz stockworks and fracture filling. The locus of magmatic-hydrothermal multiphase intrusives and brecciation associated with mineralization is distinct from the surrounding Coast Plutonic complex, although current level of mapping has not well defined the contact relationships. The multiphase system is clearly younger than the enclosing Coast Plutonic rocks.
The very large breccia-pegmatite body to the northeast is sparsely mineralized on surface but has not been tested by drilling. Previous operators suggest that the focus of mineralization may occur at depth to the northeast as interpreted by the magnetic signature.
The company has engaged an airborne magnetic and radiometric survey to define the potassic core zone.
This program is currently permitted. A new notice of work (NoW) has been filed in 2023 to expand the currently permitted program, which is still under review.
The mineralized zones are open to the north. A separate old road system 1.0 kilometre to the northwest will be investigated for possible extensions of the mineralized zone.
The mineralized zone is open to the south but may plunge to the south (under the Coast Plutonic complex). Some future drilling is warranted along roads to the south after airborne geophysics is completed.
The current results allow a reinterpretation of the geology and mineralization. The entire mineralized area is a series of multiphase magmatic-hydrothermal breccias.
David Greenway, president and chief executive officer, commented: “We are extremely encouraged by the results from this recent metallurgical testing with recoveries as high as 96.9 per cent in combination with the spectacular results from the previous drilling of up to 142.6 metres (467.8 feet) 0.279 per cent Cu, 0.0281 per cent Mo. We look forward to the next stage of exploration and development at Redonda.”
