NevGold Provides Positive Update on Limousine Butte: New Geological Model Identifies High Priority 2023 Drill Targets
July 6, 2023
Vancouver, British Columbia – July 6, 2023 – NevGold Corp. (“NevGold” or the “Company”) (TSXV:NAU) (OTCQX:NAUFF) (Frankfurt:5E50) is pleased to announce the completion of an updated geological model and 2023 drill targeting at its Limousine Butte Project, Nevada (the “Project”) located on the southern part of the Carlin Trend. The Company is also well-advanced in completing an updated NI 43-101 Technical Report for the Project, with targeted completion in July.
- Updated Geological Model Identifies Significant Mineralization Potential and New High Priority Targets: the updated geologic model for the Project has been completed incorporating new project-wide mapping and 2022 drill data. The Company has re-interpreted the district-scale and project-specific geology and has identified significant mineralization potential and numerous high priority drill targets for the 2023 drill program.
- Resurrection Ridge: the updated geological model indicates additional potential for the key host rock (Pilot Shale), particularly to the north and east of the currently defined mineralized footprint at Resurrection Ridge. (Figure 1, Figure 2)
- Cadillac Valley: the 2022 drilling at Cadillac Valley South indicates the mineralization remains open, specifically to the south and east. The Company inherited CSAMT data from McEwen Mining (TSX:MUX, NYSE:MUX) which was a key data layer utilized in the 2022 discovery at Cadillac Valley. (Figure 1, Figure 3)
- Additional Targets Identified: West Cadillac and Coffee Mug (Northeast Exploration area) have been identified as areas with strong potential for the key Pilot Shale host rock. The Company plans to drill both target areas in future drill programs. (Figure 1)
- Exploration Plan of Operations (“EPO”) Tracking According to Schedule: the EPO was submitted to the Bureau of Land Management (“BLM”) on February 8, 2023 (see News Release on February 14, 2023) and the review process is tracking according to schedule. Once approved, the EPO will allow up to 200 acres of disturbance which will permit more extensive future drill programs at the Project.
- Updated Technical Report: the Company is well-advanced in completing an updated NI 43-101 Technical Report (the “Report”) at Limousine Butte. Targeted completion for the Report is July.
NevGold CEO, Brandon Bonifacio, comments: “Although we have started the year focusing our drilling efforts at Nutmeg Mountain in Idaho, Limousine Butte remains an important asset for the company. After our inaugural drill program, we have spent the past approximate 6 months re-interpreting the data and updating the geological model which has led to many key positive developments. As expected over the course of the 2022 drill program, we uncovered many promising areas at the project that were historically not drill-tested. We have incorporated the new drill data into the geological database, and we have re-envisioned the entire Limousine Butte Project. There are a number of new, high-priority targets that are focused on expanding the mineralized areas at Resurrection Ridge and Cadillac Valley, and finding new areas of mineralization within the larger project boundary. We are pleased with what we have been able to accomplish over the past 24 months at Limousine Butte, and we are looking forward to having a drill rig back on the project.”
NevGold VP Exploration, Derick Unger, comments: “Limousine Butte continues to show exciting potential as we broaden our understanding of the geology and distribution of gold on the property. The detailed work completed by previous operators and academic studies has given us a strong foundation to build upon. Our work to compile all this data into an updated geologic model, along with our drilling, mapping, and sampling, over the past 24 months has strengthened our targeting concepts and identified promising new areas that have not been previously drill tested. The recognition that faulting has offset the favorable host rocks and concealed them under unmineralized lithologies or post-mineral cover opens significant new areas at Limousine Butte with no previous drilling. We are also closely monitoring the extensive exploration activity occurring on neighbouring properties which forms an important aspect of the district-scale geology. We will continue to focus on expanding the gold mineralization at Resurrection Ridge and Cadillac Valley, as well as targeting the discovery of new mineralized areas within the larger Limousine Butte Project.”
Limousine Butte: Exploration and Geology Summary
Updated geologic mapping along with 3-D modeling of the 2022 drill results determined that the Exchequer Fault, one of the main hosts of mineralization at the adjacent Cherry Creek Project, has significant right-lateral strike-slip offset along the Cherry Creek Range. The right lateral strike-slip offset is specifically seen immediately south of the historical Golden Butte mine where there is limited gold mineralization. This development in the structural model has identified highly prospective areas southwest of Resurrection Ridge in a new area named the “Connector Zone”, and northeast of Resurrection Ridge in the area leading to the gold mineralization at Coffee Mug. (Figure 1)
Another key development at Resurrection Ridge is the identification of dolomite units having been thrust faulted over the more prospective Pilot Shale unit on the northeastern portion of the target. (Figure 2) This explains why historical drilling east of the previously mined Golden Butte pit had gold mineralization situated beneath the older dolomite unit. The historical drilling was not followed up on previously because of different interpretations of the faulting in the area. There are other prospective areas where this may have occurred at the Project, and this remains a new target concept to drill test in the future.
Connector Zone (Connection Between Resurrection Ridge and Cadillac Valley)
Reinterpretation of the geology in the 2 km gap (Connector Zone) between the Resurrection Ridge and Cadillac Valley zones indicates the Exchequer Fault has created significant right-lateral fault offset between the two target areas. The minimal historical drilling in this area did not take the fault offset into account. Additional drilling to test both sides of the Exchequer Fault where it is expected to cross-cut favorable host rocks is needed to test for new gold zones between Resurrection Ridge and Cadillac Valley.
Cadillac Valley was a key focus of drilling in 2022 and the results uncovered significant mineralization of thick, oxide gold intercepts over a large footprint spanning over 1.6 km northeast to southwest, and over 450 meters laterally. (Figure 3) After interpretation and 3-D modeling of the 2022 results, the Company has identified opportunities to discover new mineralization to the south and east, and within the large, mineralized footprint that has been defined to date.
At West Cadillac, preliminary drilling in 2022 identified Pilot Shale host rock with anomalous gold values at the north end of Black Mountain Range under barren dolomites. Geologic mapping and modeling of this area indicates the Exchequer Fault intersects northwest striking antithetic faults, which may be prospective for gold mineralization.
The Coffee Mug, Ticup, and Epex targets have been re-interpreted due to the new understanding of the orientation of the Exchequer and Black Metals faults and their important role in the formation of the Carlin-type gold deposits at the Project. Both faults are major hosts and fluid conduits for the mineralization historically mined at the adjacent Cherry Creek Project. The recent work by the Company indicates the right-lateral movement along the Exchequer Fault north of Resurrection Ridge offsets the mineralization east into the Coffee Mug zone and appears to have been the major fault related to the gold mineralization at Epex. Similarly, mineralization at Ticup is formed where the Black Metals Fault cross-cuts and offsets the Pilot Shale.
Limousine Butte 2023 Drill Program: The 2023 drill program will continue to focus on expanding the mineralization at Resurrection Ridge and Cadillac Valley, as well as drilling the preliminary exploration targets including the Connector Zone, Coffee Mug, and some of the other identified property-wide targets. A key aspect of the updated geologic model is modeling the distribution of jasperoid developed in the Pilot Shale and other gold-bearing host rocks. Jasperoid often forms during the gold deposition event and can either be an important host of mineralization or serve as a vectoring tool towards mineralization. The recently completed mapping and modeling of the jasperoids emplaced at the Project has highlighted numerous important drill targets for the 2023 drill program. (Figure 1, Figure 2, Figure 3)
Resurrection Ridge continues to show strong potential for expansion of the near-surface, oxide gold mineralized footprint. The 2023 drilling will focus on testing north and east of the currently defined oxide gold mineralization, which remains open. These areas were previously not properly explored because of the presence of older dolomite rocks, which are not viewed as a prospective host rock for gold mineralization. Detailed mapping has determined these older dolomites were faulted over the top of the favorable Pilot Shale unit, which is an important host of gold in Nevada. (Figure 2) Additionally, updated geologic mapping data indicates the potential for right-lateral offset of mineralization along the Exchequer Fault, which is the major gold-bearing fault in the historical Golden Butte mine. Testing for additional oxide gold mineralization along the Exchequer Fault and under the barren dolomites will form the key targets at Resurrection Ridge.
Cadillac Valley has strong potential for further oxide gold discovery. The 2023 drilling will focus on expanding the currently defined mineralized footprint by testing the open ground south and east of the Cadillac Valley South discovery holes (CV22-006 and CV22-007). CSAMT geophysics data and very limited historical drilling indicates that there is additional discovery potential further south of CV22-006 and CV22-007. Other key targets are the open areas within the defined oxide gold mineralized footprint with the goal of connecting the mineralized zones. There is also up-dip shallow mineralization potential to the east of the defined Cadillac Valley oxide gold mineralization, and West Cadillac is a prospective area with identified Pilot Shale and anomalous gold.
The Connector Zone is a newly identified target spanning over 2 km between Resurrection Ridge and Cadillac Valley. The area has had minimal historical drilling, and due to the right-lateral offset along the Exchequer Fault, there is the potential to connect the Resurrection Ridge and Cadillac Valley mineralized zones.
Project-Wide Exploration is planned to follow-up on targets identified at Coffee Mug, Teacup and Epex. The new understanding of the orientations and importance of the Exchequer and Black Metals faults in these areas creates new target opportunities that have not been previously drill tested. Preliminary targeting will be driven by additional geologic mapping, surface sampling, and geophysical surveys.
