EXPLORATION TECHNOLOGY potential district sized project requires a capacity for advanced reviewing , interpretation and processing of multiple data sets in order to generate the best of several drill prospects . We are confident that GoldSpot ' s technology will bring these targets to light and assist us in uncovering Canada ' s next high-grade silver district .”
GoldSpot will help delineate drill-ready targets for high-grade silver , copper , lead , and zinc mineralisation , as well as identify prospective areas regionally . GoldSpot ' s subject matter experts will homogenise , integrate , process , and interpret exploration datasets such as geological maps , drill logs , geophysics , surface and downhole geochemistry , and structural orientation data . The interpreted and derived products will be used as input layers to GoldSpot ' s proprietary AI ( machine learning ) techniques , which will then be validated by the company ' s team of expert geoscientists , in collaboration with Sterling Metals ’ technical team .
O3 backs up drilling expansion with Mira AI approach
O3 Mining Inc recently announce it is resuming drilling with 12 drill rigs to continue executing the well-funded 150,000 m drilling program on its properties in Val-d ' Or Québec , Canada . As planned , the increase to 12 rigs will allow the company to take advantage of the freezing winter conditions to test targets located in humid areas . Four rigs are operating on the Malartic property where a total of 45,000 m of drilling is planned , and eight will focus on the Alpha property for a total of 100,000 m of planned drilling . At Malartic , where the Marban gold project is located , the drilling is testing the extensions of the ore deposits included in the PEA to grow the mineral resource base . Drilling will specifically target the Norlartic – Kierens , North-North , Marban , and Gold Hawk deposits . Other targets include extensions of historically mineralised zones located within three kilometres of the PEA pit shells , offering additional potential to increase the resources within the Marban project area . These targets include Gold Hawk , Orion # 8 , MK , and Marban NE .
The eight drill rigs at Alpha will continue to expand the Bulldog deposit at depth and laterally , explore depth extensions of Orenada # 2 , Orenada # 4 down to 800 m vertically . Additionally , it will follow-up on the promising intercepts at Simkar , explore extensions of the Epsilon zone ( Golden Valley option ) and the Akasaba deposit , and finally , it will test several targets generated from a combination of in-house data compilation and AI targeting study by Mira Geoscience .
O3 Mining engaged Mira Geoscience Ltd in Westmount , Quebec to conduct modelling and exploration targeting over its Alpha property in Val D ’ Or , Québec , using AI . O3 Mining says it seeks to actively minimise exploration risks and mitigate costs by using proven cutting-edge technology .
Mira used drilling and mapping databases , geochemical samples , Induced Polarisation ( IP ), Electromagnetic ( EM ), magnetic and gravity datasets and other public data , to provide a regional scale targeting model of the Alpha Property to assist with resource expansion and regional exploration . A total of 661,760 m in 2,400 drill holes , over 2,000 surface assays , 160,000 assays for gold and base metals plus 25,000 multi element assays , 400 line kilometres of IP , 5,500 line kilometres of Mag and over 700 line kilometres of EM were used .
“ The Alpha property is an 80 square kilometre property located in the heart of the Val D ’ Or district hosting approximately 40 historical gold and coppergold zones in numerous geological environments . Therefore , prioritisation of drilling targets is key to maximise probabilities to rapidly discover significant mineral deposits on the property ,” says Jose Vizquerra , President and CEO of O3 Mining . “ The application of the Mira innovative AI methodology is part of an integrated strategy to accomplish this task and come up with the best targets , which in turn will produce the best results and bring the most value to our shareholders .”
The deliverables produced for O3 Mining include the following : n Regional scale interpretation including surfaces from structural and stratigraphic modelling from the SKUA platform in the Gocad Mining Suite © software ( GMS ); n Intrusion surfaces from unconstrained and geometry inversion of magnetic data ; n Leapfrog dynamic model ; and n Targeting voxet with constrained inversion results , geochemistry interpolation , feature engineered variables and prospectivity score results . Using the data populated into a 3D voxet comprising cells of 25 m x 25 m x 25 m , Mira conducted different targeting exercises combining knowledge-driven and data-driven ( supervised machine learning ) methods . The knowledge-driven exercise combined the experience of O3 Mining ’ s geologists using an index overlay approach to generate mineralisation probabilities throughout the model . The drilling information was used to construct
O3 Mining engaged Mira Geoscience Ltd in Westmount , Quebec to conduct modelling and exploration targeting over its Alpha property in Val D ’ Or
predictive models using a random forest classification approach . Once the predictive model was deemed strong enough in making an accurate prediction on known mineralisation , it was applied to the voxet to estimate the likelihood of each cells to be mineralised . By combining the different prospectivity scores produced by the targeting exercises , Mira produced a set of mineral prospectivity indices ( MPI ) for the different types of mineralisation observed on the Alpha Property .
Minerva booked by Freeport for its AI approach
Minerva Intelligence Inc , an artificial intelligence company focused on knowledge engineering based in Vancouver , last year said it had signed a contract with Freeport Resources Inc for the provision of all components of the company ’ s TERRA Mining AI suite , including the Company ’ s DRIVER , TARGET , SOLACE and LEO solutions . Freeport recently acquired Quidum Resources and , through its wholly owned subsidiary Highlands Pacific Resources Ltd , controls the Star Mountains project in Papua New Guinea . Freeport is applying Minerva ’ s technology to the Star Mountains project in order to enhance its next phases of surface and sub-surface exploration of the extensive property , which is located close to the Ok Tedi mine .
Freeport is utilising DRIVER , Minerva ’ s cutting-edge AI software for evaluation of multi-element drilling data ; TARGET , for identifying auditable new drilling targets using AI ; SOLACE , for harmonising and standardising large data sets ; and LEO , for quickly searching through all of their data .
“ We continue to see growing demand for our TERRA Mining AI solutions as innovative companies
such as Freeport actively seek out technologies that make their workflow processes more efficient and more insightful ,” said Scott Tillman , Chief Executive
