Viridis Mining and Minerals makes major ionic clay discovery at Colossus project

November 26, 2023

Viridis Mining and Minerals (ASX: VMM) has made a major ionic adsorption clay (IAC) rare earth elements (REE) discovery at the Colossus project in Brazil, including an assay of 3,285 parts per million total rare earth oxides (TREO) from surface.


Initial results from auger and diamond drilling have revealed an IAC body at the project’s Fazenda prospect measuring up to 20 metres in thickness with a weighted average grade of 2,938ppm TREO.


The first two diamond holes at Fazenda returned “outstanding” REE-rich clay intercepts from surface such as 40m at 2,162ppm TREO including 17m at 3,042ppm total rare earth oxides (TREO) (34% MREO, or magnetic rare earth oxides) from 7m; and 21m at 2,132ppm TREO including 10m at 2,760ppm TREO (32% MREO) from 11m.


Cupim South IAC body

At the greenfields Cupim South target, Viridis has identified a similar IAC body up to 45m thick with a weighted average grade of 3,460ppm TREO.


The first three diamond holes returned 24m at 4,573ppm TREO (38% MREO) including 14m at 6,177ppm TREO (40% MREO) from 3m; 15m at 2,214ppm TREO (29% MREO); and 46m at 3,285ppm TREO (27% MREO) within a broader section of 65m at 2,799ppm TREO (28% MREO).


The results represent a small portion of the Viridis exploration program completed to date, and have demonstrated homogenous high-grade REE mineralisation across multiple Colossus tenements.


They signify a major IAC discovery within the Poços de Caldas alkaline complex and could potentially underpin a world-class maiden resource estimate.


Highest-Grade Deposit

Executive chair Agha Shahzad Pervez said the grades position Colossus to potentially become the world’s highest-grade ionic clay rare earths deposit.


“As we advance our exploration program, we are encountering widespread thick saprolite clay profiles which exemplify the potential for Colossus to host a world-class resource in terms of size and grade,” he said.


One of the diamond holes completed at Cupim South is already the third-best intercept reported in the entire complex in terms of grade and thickness.



“This is exceptional given it is only the third diamond hole assay received,” Mr Pervez added.

Queensland breaks ground on CopperString

July 9, 2024
The Queensland Government has broken ground on the first construction works of the $5 billion CopperString project. Work commenced yesterday on the CopperString projects’ first and largest workforce accommodation site. The site will house those charged with building the project’s 840km high-voltage transmission line that will connect Mount Isa to the ‘SuperGrid’ for the first time. The workforce accommodation will house up to 550 construction workers at its peak. These workers will construct a nearby substation and progress early stages of the transmission line development heading west from Hughenden out to Mount Isa. Supercharging the state’s north-west aims to unlock Queensland’s $500 billion north-west minerals province. It’s expected CopperString will be complete in 2029, weather and construction conditions permitting. Queensland Premier Stephen Miles said CopperString is the biggest ever expansion to the state’s publicly owned energy system. “Queenslanders deserve cheaper, cleaner, more reliable energy – to power their homes, our schools, hospitals, shopping centres and more,” Miles said . “CopperString will be the catalyst for transforming Queensland’s north and north-west – opening up mining opportunities, creating more jobs and unlocking critical minerals which will be essential in developing renewable technologies. “This is the start of a long and exciting future for the region and our state.” Commencing later this month, project owner, Queensland Powerlink, will be offering free sessions for businesses along the CopperString corridor to build their capabilities. The program includes five workshops and one-on-one assistance to help businesses build confidence to bid on major projects and supply chain work in the region. “All of North Queensland understands the immense opportunities that CopperString presents for local jobs both directly and indirectly which is why this is such a momentous day,” Resources and Critical Minerals Minister Scott Stewart said.  “Critical minerals are the next big boom for the resources industry and the feedback I’ve had from companies is that this project is key to unlocking those opportunities.” Source: https://www.australianmining.com.au/queensland-breaks-ground-on-copperstring/

Showcasing the best in underground mining

July 8, 2024
Underground mines are busy places, and it’s vital companies are on top of their processes to enable an efficient and safe underground operation. Whether it’s having the best equipment to drive higher production, maximise return on investment, minimise waste or keep workers out of harm’s way, mining companies benefit from understanding and investing in the right underground technologies.

BHP goes green at ‘world’s largest’ copper mine

July 8, 2024
BHP has started environmental processing to have the transport at its Escondida copper mine in Chile transitioned to an electric trolley system. The Big Australian will invest around $US250 million ($371.6 million) in the project at Escondida, which it owns in a joint venture with Rio Tinto. The funds will go towards installing key infrastructure to electrically assist the movement of extraction trucks in areas where the highest fuel consumption currently takes place. BHP has submitted an environmental impact statement to the Environmental Impact Assessment System in Chile. “The electric trolley system is one of the initiatives with which we seek to move towards a safer and more sustainable way of operating hand in hand with technology,” BHP Escondida president Alejandro Tapia said . “This project will allow us to reduce the fuel consumption of our extraction trucks and thus advance our goal of net-zero operational greenhouse gas emissions by 2050.” The project includes the construction of a new electrical substation and transmission lines both inside and around the Escondida Norte pit. These facilities will electrically assist the movement of trucks inside the mine in the areas where they go up loaded with ore and, consequently, consume more fuel. With this new technology, instead of using diesel, they will be propelled by electrical power, reducing greenhouse gas emissions and improving productivity associated with truck performance given the higher travel speed. Once construction kicks off up to 160 jobs are expected to be created. The trolley project is in addition to other technological transformation initiatives that the company maintains in different stages of study and execution, including the progressive incorporation of autonomy in its mining equipment.  To date, Escondida has six autonomous trucks in full operation and by 2025 it expects to have the largest fleet of autonomous equipment in South America.
