RENO, Nev., June 09, 2022 (GLOBE NEWSWIRE) —
- Drillhole SGVC014 stopped at 534 metres due to lost tooling, being redrilled as SGVC014A, and now at 640 metres.
- Features of significance in the ~600 metres logged match the Company’s expectations based on its exploration model.
- Alteration, geochemistry, structure, and lithology all continue to provide evidence for a characteristic setting for Carlin-type mineralization that has been exploited by mineralized hydrothermal fluids.
- Pathfinder and alteration intensities suggest the mineralizing fluids seen in the upper units drilled so far were sourced from depth in the direction of the Hales Formation, which underlies the Goodwin Formation that SGVC014A is drilling through presently.
- Results from upper units highlight importance of completing the drillholes in the southern area of project to their planned ~1,000 metre depths to reach the Hales Formation, the targeted host unit at the project.
RENO, Nevada, June 9, 2022 (GLOBE NEWSWIRE) — Nevada Exploration Inc. (“NGE” or the “Company”) (TSX-V:NGE; OTCQB:NVDEF) is pleased to provide an update from the ongoing core drilling program at its South Grass Valley Carlin-type gold project (the “Project”) located 50 kilometres south-southwest of Nevada Gold Mines’ Cortez complex.
Drillhole SGVC014 was stopped in early May at 575 metres due to the drill steel breaking at 347 metres (~228 metres above the bottom of the hole), which NGE’s drill contractor Drill NV believes was the result of ongoing challenges associated with voids within the bedrock. Drill NV has restarted drilling in this location with drillhole SGVC014A, has successfully installed PQ-sized drill rods to a depth of 356 metres to effectively case off the challenging interval, and is now continuing to core drill with HQ rods. SGVC014A is presently at a depth of 640 metres.
NGE has now completed logging and collecting pXRF-derived geochemistry from the core from SGVC014 (core samples collected from 359 to 575 metres). As suggested by the early logging, the observations and data from the completed logging are consistent with the Company’s exploration model at this south end of the project.
- STRATIGRAPHY: after entering the Antelope Valley Formation at 130 metres, SGVC014 continued into the Goodwin Formation. Near the bottom of the hole, the sequence of Goodwin units began to also contain what appear to be smaller intervals of the targeted Hales Formation below, differentiated as being dark “sooty” units containing large amounts of remobilized black carbon, which suggests SGVC014 was potentially nearing the contact with the Hales Formation (at a depth similar to where SGVC014A is now drilling).
- CONTACT METAMORPHIC ALTERATION: the major units in SGVC014/SGVC014A exhibit more coarsely recrystallized limestone (marble) and recrystallized silt and mud (hornfels) than seen in SGVR015, SGVC004, SGVC005, and SGVC013A, characteristic of higher-grade thermal effects consistent with the location of SGVC014/SGVC014A along the projected margin of the Grass Valley Stock (as predicted by NGE’s geologic model). The products of these thermal effects represent important rock preparation processes controlling some of the highest-grade mineralization at each of Nevada’s three largest Carlin-type districts.
- STRUCTURE: the units in SGVC014/SGVC014A have been crosscut by numerous fracture and fault zones, and together show frequent and substantial changes in bedding consistent with intense folding, all of which is to be expected proximal to a major intrusive. The introduction of small gouge-bounded blocks of Hales Formation alternating with the Goodwin Formation suggest a series of repeated high-angle and low-angle faults within the lower plate bedrock along the intrusive margin, further demonstrating the structural complexity in this area of the project.
- ALTERATION & OXIDATION: the high-angle faults and fractures seen in SGVC014/SGVC014A are associated with both intense oxidation and hydrothermal argillic alteration, evidencing the importance of these high-angle features in supporting and focusing vertical fluid flow along the margin of the Grass Valley Stock. Importantly, as seen in SGVC013A as well, the Carlin-type alteration features crosscut the metamorphic effects of the intrusive (dated at 168 Mya) and support NGE’s geologic model that the hydrothermal system at South Grass Valley post-dates the Grass Valley Stock, consistent with the timing of Nevada’s Carlin-type mineralizing events (approximately 40 – 30 Mya).
- GEOCHEMISTRY: The results of NGE’s down-hole near-time pXRF geochemistry program confirm that the alteration products of the fracture-controlled fluid flow – projected to be travelling upwards into the Goodwin Formation from the Hales Formation below – are associated with highly anomalous Carlin-type pathfinders, and importantly that these pathfinder concentrations along the fractures generally increase with depth and proximity towards the Hales, NGE’s primary targeted host unit at the project.

About Nevada Exploration Inc.
Led by an international team of proven explorers, NGE is disrupting Nevada’s exploration industry by applying new technology to systematically explore for the second half of Nevada’s gold endowment waiting to be discovered beneath Nevada’s valley basins. NGE is advancing a portfolio of new gold exploration projects, primarily focused on three district-scale Carlin-type gold projects, which includes its flagship South Grass Valley project where it is currently drilling 50 kilometres south-southwest of the Nevada Gold Mines (Barrick Gold Corp. and Newmont Corporation joint venture) Cortez complex.
