EMINENT GRAVITY GEOPHYSICS REVEALS REGIONAL-SCALE GOLD TARGETS AT HSRP IN NEVADA
Eminent Gold Corp. has released the results of its recently completed gravity program at its Hot Springs Range project (HSRP), one of Nevada's most significant new gold districts. The data were acquired by Tom Carpenter Geophysical Services and subsequently processed, analyzed and interpreted by Jim Wright of JL Wright Geophysics, a veteran with over five decades of experience, much of it focused in Nevada.
Drawing on his extensive work in similar Nevada districts and a thorough evaluation of Eminent's existing data sets, Mr. Wright has identified five distinct exploration targets.
Three of these targets lie within the northeast-trending Hot Springs Range corridor, corroborating Eminent's existing Otis, Sitka and Eden targets originally delineated through aerial photo interpretation. This marks the first geophysical confirmation of these potentially mineralized structures, pinpointing their locations and demonstrating that the corridor hosts over 10 kilometres of cumulative strike length, defined by multiple northeast-trending faults. Most of these structures are obscured by postmineral basalt flows and alluvial cover.
Paul Sun, president and chief executive officer of the company, commented:
"This is shaping up to be one of the most compelling exploration opportunities in Nevada. As we continue to advance the project, our thesis that this project represents an analogue to the world-class Getchell trend is being increasingly validated, supported by growing evidence for multiple discovery opportunities across the system. With drilling set to resume shortly and active progress across our other two projects, Gilbert South and Celts, Eminent is entering a pivotal phase of growth."
Eminent has subdivided the Hot Springs Range corridor into:
-
The Northeast Otis corridor, a portion of which was drilled by Eminent at its southern extent;
-
The Eden corridor;
-
The Southwest Otis corridor.
The Otis and Eden targets are separated by a prominent gravity low, interpreted as a postmineral basin.
Eminent's prior drilling program validated the potential of these structures, intersecting gold mineralization in all three holes along a 400-metre segment of the northeast-trending Otis fault (see news release dated June 19, 2025). This northeast structural orientation is characteristic of many Carlin-type deposits, notably the Turquoise Ridge deposit, located 15 kilometres southeast of the Hot Springs Range project, underscoring the significance of these newly identified faults.
Dan McCoy, chief geologist and director of the company, commented:
"This gravity survey has uncovered regional-scale potential across HSRP that far exceeds our initial expectations. What began as three distinct targets is now part of a much larger, structurally connected system with multiple zones showing equal promise. Over the coming months, we'll be conducting detailed prospecting, mapping and potentially additional geophysical programs to validate these targets. At the same time, we're preparing to resume drilling on the open-ended mineralization already confirmed in our earlier program."
The remaining two targets are defined by the largest density contrasts observed on the property. Target 4 is a high-density anomaly, interpreted by Mr. Wright as a possible magmatic intrusion. Such intrusions are critical across Nevada's major Carlin trends as they induce structural and chemical disruptions in surrounding sedimentary host rocks, enhancing both permeability and reactivity.
Target 5 is a distinct gravity low, interpreted as a recessively weathered basin infilled with postmineral basalt. These basins typically form due to structural extension and alteration of original host rocks, making them highly prospective exploration targets.
Geophysical survey methods
A total of 1,002 gravity stations comprise the unedited data set. The gravity station distribution includes a 400-metre square grid over the Eden target and 200-metre square grid over the Otis target.
Relative gravity measurements were made with a LaCoste & Romberg Model-G gravity meters. Survey control was provided by a Leica survey system operated in rapid static mode. The gravity surveys are tied to the U.S. Department of Defense gravity base at Winnemucca (DoD Reference 0474-1).
Field data, including station identifier, local time, gravity reading, measured slope and operator remarks, were recorded in the field in notebooks. The recorded data were then entered into a notebook computer in the form of GeoSoft RAW gravity files. Survey co-ordinates were transferred digitally. All gravity data processing was performed with the Xcelleration Gravity module of Oasis montaj (Version 7.0). The gravity data were processed to Complete Bouguer Gravity over a range of densities from 2.00 through 3.00 grams per cubic centimetre at steps of 0.05 g/cc centimetre using standard procedures and formulas.
Terrain corrections were calculated to a distance of 167 kilometres for each gravity station. The terrain correction for the distance of zero to 10 metres around each station was calculated using a sloped triangle method with the average slopes measured in the field; correction for the distance of 10 to 2,000 metres around each station was calculated using a combination of a prism method and a sectional ring method with digital terrain from 10-metre digital elevation models (DEM). The terrain correction for the distance of two to 167 kilometres around each station was calculated using the sectional ring method and digital terrain from 90-metre DEMs.
Data processing
Data provided by the field crew includes the gravity data corrected to the complete Bouguer anomaly (CBA) stage for a number of densities. Determination of the most suitable Bouguer density is critical for removal of topographic effects in the data. Three density profiles were selected for analysis to establish the Bouguer density for processing. They were selected to cross rugged topographic features as well as a variety of lithologies mapped by Jones (1987).
A review of the density profiles indicates that a reasonable overall density for the lithologies involved is 2.50 g/cc. The CBA 2.50 g/cc data were gridded with a Kriging algorithm using a spacing of 50 metres, which is 25 per cent of the 200-metre detail grid station spacing. This product is termed the CBA or GRAV. The CBA data were processed with a proprietary procedure to produce a smoothed regional grid (GRAV_UC), which, subtracted from the CBA grid, yields a residual (GRAV_RES) grid. Finally, the total horizontal gradient (GRAV_HG) and first vertical derivatives (GRAV_VD) were computed from the CBA gravity.
The initial figure produced is the standard complete Bouguer gravity over topography. This is the standard data product from which other secondary products are derived. The data range is 18 milligals. Secondary targets derived from this include figures that show the horizontal gradient over Google Earth, residual over geology, vertical derivative over topography and upward continued gravity with contours over topography.
All products of this study were used by Mr. Wright to interpret the structures and contacts present on the property.

Cautionary statement
Mineralization, resources or reserves reported on adjacent or nearby properties or within the same geological trend are not necessarily indicative of mineralization at the Hot Springs Range project. Investors should not rely on such comparisons as a basis for potential mineralization or economic viability at the company's property. All exploration results are subject to further analysis, and there is no guarantee of future resource definition or development.
