Vancouver, BC – Minerva Intelligence Inc. (TSXV:MVAI) (“Minerva” or “the Company”), an artificial intelligence (AI) company focused on knowledge engineering, is pleased to announce delivery of results of geochemical analysis for the Freegold Mountain Project, owned by Triumph Gold Corp. (“Triumph Gold” or “Triumph) (TSXV: TIG). Minerva utilized both DRIVER, the Company’s cutting-edge AI software, and K-Means Cluster Analysis to undertake evaluation of multi-element drilling data in order to enhance understanding of Triumph’s Nucleus and Revenue deposit areas.
Results contributed to Triumph’s understanding of the complex geology and mineralization of the Nucleus and Revenue deposits, providing valuable information with which to guide plans for the next phase of evaluation of the extensive property. Results included:
- At the Nucleus Deposit, DRIVER revealed new vectors to gold and copper mineralization not characterized in the current mineral resource, delivering superior exploration models and a clear path forward for resource expansion
- At the Revenue Deposit, DRIVER has identified under-evaluated areas at the northeast and southern contacts of the intrusive breccia providing credible drill-ready exploration targets
- In the Revenue-Nucleus Area, K-Means Cluster Analysis highlighted semi-quantitative alteration styles allowing for robust modelling and vectoring toward zones of high-grade mineralization
John Anderson, Triumph Gold’s Interim CEO, Chairman and Director, was thrilled with the results. “DRIVER is like a silver bullet for exploration targeting,” said Anderson. “We saved hundreds of thousands of dollars using DRIVER to identify and verify a large number of exploration targets, giving us absolute confidence in our upcoming drill program.”
“Our ongoing relationship with Triumph Gold is a win-win for our respective companies,” said Minerva CEO Scott Tillman. “Triumph’s embrace of our state-of-the-art mining and exploration software is proof positive of the value our cognitive AI technology can bring to mining and exploration companies, regardless of their size.”
Minerva’s DRIVER software analyzed a comprehensive database of analytical results compiled from multiple generations of drilling on the Freegold Mountain Project, then delivered multiple wireframes models and preferred orientation data for each element. Data for two primary areas of interest, the Nucleus and Revenue deposit areas, were evaluated using DRIVER.
Nucleus is a focused deposit, having at least two steeply dipping dyke swarms, 1) generally east-west trending Quartz Feldspar Porphyry dykes, and 2) a northwest-southeast trending felsic dyke swarm. In addition, Leucogranite in the northern portion of the deposit area is present as southward projecting dykes and/or apophyses alternating with Schist.
In the Revenue deposit area, the main areas of interest are the Blue Sky and WAu breccias within the Revenue and Blue Sky Zones, both localized within, or immediately adjacent to, an Intrusive Tuff Breccia, itself hosted by Granodiorite. Several other mineralized centres have been previously identified in the Revenue deposit area, including the Gruder Revenue West, Grainger and Keirsten zones.
Key outcomes for the Nucleus Deposit were in close agreement:
1) between DRIVER results, specifically the linear optimal orientation identified for gold, and the gold probability shell developed for the Resource Estimate, and
2) between the linear optimal orientation for gold and the spatially associated felsic dyke swarm as a dominant control on gold mineralization.
The gold probability shell delineated for the Resource Estimate is more rigorously defined than comparative DRIVER volumes. Although the respective volumes vary in detail, overall outlines defined by the 0.1 g/t shell are comparable, interpreted to suggest DRIVER volumes represent a cost-effective means to determine whether subsequent, more rigorously defined Resource Estimation is warranted. Furthermore, DRIVER output can be utilized to similarly evaluate other metals as potential co- and by-products on a semi-quantitative basis.
DRIVER results for the Revenue Deposit area are dominated by the high density of drilling in the eastern Revenue and western Blue Sky zones, spatially associated with the Blue Sky and WAu breccias. As a result, groups identified, and optimal orientations determined, tend to be localized in this area. Notable exceptions are groups identified along the southwest margin of the Revenue Zone, at the mutual boundary with the Guder Zone.
DRIVER results for Gold and Copper delineate the southern contact between Intrusive Tuff Breccia and Biotite Granodiorite, clearly defining areas recommended for subsequent evaluation. In addition, results are interpreted to indicate the northern contact may be similarly mineralized, but relatively under evaluated. This supports interpretation of K-means Cluster Analysis results, similarly interpreted to indicate mineral potential along the northern margin of the Revenue Zone. DRIVER results with respect to the Intrusive Tuff Breccia agree very well with Triumph’s lithological block model. On the basis of these results, very good mineral potential is interpreted along the entire southern contact, as well as to depth, representing a very good, although progressively deeper, drill target.
Minerva is able to deliver valuable insights (such as those above) through their proprietary DRIVER software, effectively identifying multi-element zones in drilling data that are typically too time-consuming and complicated to identify by conventional means. Multi-element zones identified through DRIVER can then be evaluated with respect to relevant lithologies and structures. A key outcome is that potential exploration vectors can be identified from a company’s exploration data relying on cost-effective computer reasoning. Minerva’s cognitive reasoning platform then compares identified elemental associations to hundreds of past and present mines throughout the world, identifying those most similar to a client’s targets, which can serve as reliable models upon which geologists can confidently develop their exploration and/or development strategies.
K-Means Cluster Analysis
- Nucleus Deposit Area
Intervals identified as “Sulphide Zone” have higher iron values, consistent with secondary minerals associated with both alteration and mineralization. These intervals are closely associated with intervals designated as “Skarn”, interpreted to indicate skarn-style metasomatism is a dominant control on both alteration and associated sulphide mineralization.
Potassium tends to be normal or depressed. Magnesium alteration is interpreted to be preferentially associated with Schist, having a low to very low content in Cluster 1 (dominated by Granitoids).
Lithologies within the Nucleus Deposit area have been subjected to a highly variable degree of potassic alteration, predominantly expressed as secondary sericite rather than alkali feldspar (“Kspar”) alteration. Alteration trends are also interpreted to indicate secondary plagioclase (predominantly Albite), largely independent of Kspar. These results are interpreted to be consistent with predominantly skarn-style metasomatism.
A very small proportion of intervals are interpreted to suggest Kspar alteration, potentially indicating a subtle Porphyry-style signature. Furthermore, a small proportion of the data are interpreted to indicate more extensive alteration, expressed as Chlorite and/or Clay alteration.
B. Precious Metal Mineralization
Results are interpreted to suggest Skarn, with closely associated Sulphide Zone mineralization, predominate in the Nucleus Deposit area. The cluster having the highest proportion of skarn has relatively few Sulphide Zone intervals, however, interpreted to represent more distal occurrences. More extensive skarn-style alteration is interpreted to be associated with a higher level of mineralization. Clusters 13 through 17 are of the most interest with respect to Ag and Au (as precious metals), together with Cu (strongly associated with the precious metals in these clusters).
Clusters 1 through 9 have a high number of anomalous values for Au and Cu, without accompanying Ag, interpreted to suggest a separate and distinct deposit style as they are dominated by “Granitoids” and Schist, as opposed to Skarn, lithologies.
2. Revenue Deposit area
Results for barium, calcium, potassium, and sodium have a very similar character, delineating highly localized and, potentially, focused alteration centres. The Blue Sky Porphyry area and the southern margin of the Intrusive Tuff Breccia (Revenue Zone), together with the Granger and Keirsten zones, document very high values for these elements, interpreted to reflect the effects of alteration. There is a subtle difference between barium and calcium, potassium and sodium, in that barium has a local high over an unnamed zone south of the Keirsten Zone, not evident for the other elements. In addition, barium and potassium document a larger areal footprint, interpreted as a potential halo to highly altered centres.
Arsenic, iron, and magnesium have a similar surface expression and document a larger areal footprint. The largest centre, together with the most extensive alteration, is associated with the Blue Sky Porphyry and contacts of Intrusive Tuff Breccia with host granites; Biotite Granodiorite along the southern margin of the Revenue Zone trending west to the Revenue West Zone, and Biotite Hornblende Quartz Monzonite to Granodiorite along the northeast margin of the Intrusive Tuff Breccia in the Revenue Zone.
Localized, slightly smaller (potentially underexplored) centres documenting interpreted high-grade alteration include the Granger, Keirsten and Revenue West, as well as unnamed centres south of the Keirsten Zone and east of the Revenue Camp, north of the Revenue Zone. Interpreted alteration evident at each of these centres is interpreted to be very focused, as there is little evidence of a gradational decrease into (a) lower grade halo(es).
Structural control, supported by a preferred east-west orientation for the Quartz Feldspar Porphyry dyke swarm and the long dimension for the ovoid-shaped exposure of the Intrusive Tuff Breccia, is evidenced by a preferred east-west trend evident in alteration centres. The Quartz Feldspar Porphyry dyke swarm is interpreted as a control on mineralization.
In general, data document a “least altered” field, with potassic alteration, consistent with initial phyllic (muscovite) alteration, delineating a trend toward K-micas (as sericite). Subsequent alteration is evident in two populations, one interpreted to suggest “Advanced Argillic alteration” (potentially related to Porphyry-style alteration) with a second, slightly more prevalent trend, interpreted to represent “Adularia” alteration.
Strata in the Revenue Deposit area have been subjected to alkali alteration (Na depletion ± K addition). The dominant potassic phase is Muscovite, with only a small subset interpreted to indicate minor potassium feldspar (“Kspar”) alteration. Such alteration is considered consistent with the ‘Low Sulphidation’ deposit model proposed for the deposit area, with potential for subtle, highly subordinate Porphyry-style alteration.
The strongest centre of mineralization, at surface, is located in the eastern Revenue / Blue Sky Zone. The Blue Sky Zone is a centre of mineralization, while the contact of the Intrusive Tuff Breccia with immediately adjacent host “granites” is the apparent locus of mineralization along the southern and northeast margin of the Revenue Zone.
Smaller centres are evident, to varying degrees, in Granger, Keirsten, and Revenue West, as well as two unnamed centres (south of Keirsten and east of the Revenue Camp/north of the Revenue Zone). Gold has the greatest distribution at surface, followed by Ag, Pb, and Zn. Copper has a slightly more restricted expression at surface over the deposit area.
A lower proportion of drilling in the southern Blue Sky Zone / Happy Creek Gold Showing area has documented a number of high-intensity mineralized intervals. In addition, a relatively small area of anomalous mineralization is present at the western margin of the Revenue Deposit area (adjacent to the Nucleus Deposit area). Both are considered worthy of follow-up evaluation.
