Triumph Gold $TIG $TIGCF Completes #Artificial #Intelligence Study at the Freegold Mountain Project, #Yukon

Triumph Gold Corp. (TSX-V: TIG | OTCMKTS: TIGCF) (“Triumph Gold” or “the Company”) is pleased to announce that it has concluded an in-depth Artificial Intelligence (“AI”) study focused on the Revenue-Nucleus Area, a large zone of gold-copper-silver-molybdenum mineralization, within their district-scale Freegold Mountain Project (“the Project”) located in Yukon, Canada (Figure 1). The Company engaged Minerva Intelligence Inc. (“Minerva”) to utilize their cutting-edge DRIVER software along with K-Means Cluster Analysis to evaluate multi-element drilling data.

Results from Minerva’s cognitive AI analysis have enhanced Triumph’s technical understanding of the Nucleus and Revenue Deposits by providing confidence in existing models and identifying unrealized controls on mineralization. Key findings are being used to guide current exploration activities at the Freegold Mountain Project, notably:

  1. 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,
  2. At the Revenue Deposit, DRIVER has identified under-evaluated areas at northeast and southern contacts of the diatreme providing credible drill-ready exploration targets, and
  3. 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.

“As an exploration company that embraces the application of new technology, Triumph is pleased by the depth of insight provided by Minerva,” says Jesse Halle, VP Exploration for Triumph Gold. “Having over 145,000 metres of drilling at the Freegold Mountain Project, along with a massive amount of other exploration data, Minerva’s AI engine has helped sharpen the focus of our new Technical Team.”

Brian May, Chief Geoscientist for Triumph Gold adds, “DRIVER has validated Triumph’s stratigraphic and structural interpretations in the Nucleus deposit area. Multielement overlaps will be drill-tested to further confirm our technical team’s interpretations this exploration season.”

Scott Tillman, Minerva Intelligence CEO, is excited about the results. “Our ongoing relationship with Triumph Gold is a win-win for our respective companies,” said 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. Triumph’s vast amount of data made the results even better than we had expected.”

DRIVER Software 

Minerva Intelligence DRIVER software analyzed and evaluated a comprehensive database of geochemical results compiled from multiple generations of diamond drilling in the Revenue and Nucleus Mineral Resource Deposit areas of the Freegold Mountain Project.

Cost-effective computer reasoning generated orientation data for all elements in the dataset. Further work was performed on key economic elements through automated identification of optimal (“preferred”) orientations, in both planar and linear modes. These results provided potential exploration vectors from Triumph’s database that can be used to identify exploration targets in unexplored regions outside the known resources or mineral prospects.

Additionally, Minerva’s cognitive reasoning platform compared elemental association data from hundreds of past and present mines throughout the world with that of the Revenue-Nucleus Area. Comparisons between Triumph’s resources and known deposit types serve as reliable models upon which geologists can confidently develop their exploration and/or development strategies. 

Nucleus Au-Ag-Cu Deposit

The Nucleus Au-Ag-Cu deposit is a complex deposit involving early porphyry-copper and skarn mineralization overprinted with related epithermal styles of mineralization. Triumph Gold’s technical team has recently modeled the skarn-style mineralization to be preferentially located along favourable horizons within the host Yukon-Tanana metamorphic rock package, as well as at contacts with leucogranite dikes and sills. Past geochronology shows at least some of the Au-Ag-Cu mineralization is coincident with the emplacement of east-trending quartz-feldspar porphyry dikes.

The results of DRIVER’s AI analysis were many, including an independent confirmation of the probability shell developed for the 2020 Resource Estimate which was largely based on dike orientation. The close agreement of the optimal orientation and the rigorously-defined gold shell in the deposit area provides confidence in the Resource Estimate and supports this orientation as an exploration opportunity. Minerva believes this type of agreement may soon be utilized to evaluate other metals as potential co- and by-products on a semi-quantitative basis.

An additional previously unappreciated gold orientation was identified from DRIVER’s outputs at the Nucleus deposit, this time along a northwest-trending structure. This orientation is correlated with a fault corridor and coincident dike swarm and represents an additional opportunity for proximal expansion of, and exploration around, the current resource.

The preferred orientations for copper at the Nucleus deposit area resulted in a largely bimodal distribution, which had not been previously understood. The technical team is currently working on identifying underlying reasons for this distribution, along with other vectors controlling economic mineralization.

Revenue Au-Ag-Cu-Mo-W Deposit

The Revenue Deposit consists of porphyry-copper and related epithermal mineralization within a granodiorite to quartz monzonite intrusive complex. Numerous mineralized zones have been discovered at Revenue, notably the gold-copper-silver-molybdenum-bearing Blue Sky and WAu Porphyry and Epithermal Zones and the proximal mineralized diatreme breccia. Several other mineralized centres have been identified in the Revenue deposit area, including the Guder, Revenue West, Grainger, and Keirsten Zones.

Minerva’s optimal orientation DRIVER results for gold, copper, and molybdenum delineate both the southern and the northeastern contact between the diatreme breccia and the granodiorite as primary locations for further evaluation. The DRIVER results also agree very well with the current lithologic model, providing additional confidence for the technical team’s interpretations.

K-Means Cluster Analysis

K-Means Cluster (KMC) Analysis is an unsupervised learning algorithm meant to identify relationships inherent in a dataset. Unlike supervised learning methods, it does not require labeled training data from which to practice and learn, but rather uncovers native associations within the data itself. For multi-element geochemical data, it identifies potential element assemblages present in the data. If executed carefully and with appropriate data preparation, KMC Analysis can reveal complicated patterns in the data that would otherwise be missed.

Geochemical data was analyzed and evaluated using K-Means Cluster Analysis available in ioGAS software. Clusters (or groups of data records with similar geochemistry) are defined and redefined based on minimizing the distance between the data record and the cluster centre. KMC Analysis concludes when either the change in the distance of each of the data points from the respective centres for assigned cluster approaches a minimum, or the specified number of iterations is reached. Multiple iterations were attempted on the data for both the Nucleus and Revenue Deposit areas using various elements, data transforms and/or initial analytical parameters.

Nucleus Au-Ag-Cu Deposit

K-Means Cluster Analysis and subsequent interpretation though discrimination plots suggest the numerous lithologies within the Nucleus Deposit area have been subjected to variable degrees and styles of potassic alteration. Discrimination plots suggest a small proportion of the data is potassic feldspar (K-spar) alteration, implying an underlying copper-porphyry-style signature. The plots are more suggestive of potassic alteration predominantly expressed as secondary sericite. Based on molar ratios, the most recent alteration event is interpreted to preferentially involve plagioclase (predominantly albite) and is largely independent of K-spar. These observations are consistent with mineralization stemming from the intrusion of quartz-feldspar porphyry dikes from a buried porphyry intrusion.

A large portion of the results in the Nucleus Deposit area are consistent with intrusion-related skarn-type mineralization and closely-associated sulphide mineralization. The geochemistry of these high-iron areas is consistent with the appearance of secondary Ca-rich pyroxene and clinochlore. Triumph geologists believe these results are consistent with the skarn-style mineralization observed in many areas of the deposit.

Revenue Au-Ag-Cu-Mo-W Deposit

K-Means Cluster Analysis and subsequent interpretation though discrimination plots highlight the Blue Sky porphyry and contacts of diatreme breccia as the largest zone of extensive alteration, documenting high values for Ca, K and Na. Barium (Ba) is also anomalous in this zone and extends westward towards Keirsten South Zone. These zones are largely underexplored and represent targets for future work.

Specific locations in the Revenue Deposit are flagged in the K-Means Cluster Analysis work as having been subjected to alkali alteration through Na depletion and potassium addition. Results indicate that the dominant potassic phase is K-rich muscovite with only a small subset interpreted as potassium feldspar alteration. This type of alteration is consistent with the ‘low sulphidation’ deposit model proposed for the deposit area.

#Renforth #Resources $RFR Completes New Alger #Purchase

#RenforthResources $RFR has completed the New Alger #joint #venture, resulting in Renforth assuming 100% ownership of the New Alger mining concession, subject to a 2% NSR.

New Alger hosts an inferred gold resource of 237,000 ozs of gold located above a depth of 200m in the area of the former Thompson-Cadillac mine. The Thompson-Cadillac mine saw small-scale operation prior to the Second World War, resulting in the production of 21,000 ozs of gold at an average grade of 4.2 g/t Au.

Renforth_logo_final“We are happy to have attained complete ownership of New Alger. Renforth has had a long relationship with this property, successfully putting in place the first resource statement and rediscovering the gold system in the sediments. Management looks forward to, funding permitting, being able to continue to define how much gold is contained in this 1.4-kilometre portion of the Cadillac Break and in the Pontiac sediments to the south with future exploration programs,” states Nicole Brewster, president and chief executive officer of Renforth.
