Spanish Moon District

Key Statistics: Property Location, Size and Exploration Maturity

The Spanish Moon District (Spanish Moon, the Property, or the Project) is located in western Nye County, Nevada (Figure 1), only 13 km from the Round Mountain deposit which has produced 20 Moz Au (as of 2018), with 7.6 Moz more in the reserve and resource category (Figure 2) (Kinross, 2021; Patterson, 2020). The Property consists of 212 federal lode mining claims on National Forest land, as well as 2 patented lode claims, totaling 1790 hectares. There is no permanent infrastructure on the project, but work is facilitated through access by paved state highways and dirt roads. Materials, services and labor are easily available in Tonopah, Nevada and high-tension power lines could be accessed from Round Mountain if a large deposit were found.  

Historically the Property was a notable silver producer, producing over 200,000 ounces at grades ~25 oz/t before and after the turn of the 19th century (Ervine, 1973). Significant exposures of lower grades, ranging from 15-20 opt silver were reportedly left in the ground: field notes and reports from that time indicate that large, mineralized bodies of “low-grade” silver were not mined due to high milling and transportation costs and low silver prices – the price of silver dipped below $1 per ounce during the last phase of mining, leading to the abandonment of the mines, which have subsequently collapsed (Fletcher, 1907; Hunt, 1936). The property has been explored and mined on a smaller scale for a variety of other commodities, including gold, molybdenum, tungsten, lead, copper, zinc, antimony, and mercury.  

More recent surface exploration and drilling in the western portion of the Property discovered significant gold intercepts (Table 1) but did not continue primarily due to low gold prices and poor markets during that time period (DeMatties, 2003). Thus, significant intercepts, such as 13.5 m of 7.6 g/t gold, were not followed up.

Overview of the Opportunities

The Spanish Moon District is remarkably underexplored; not just because of its proximity to the world class Round Mountain gold deposit, but because the property has both existing historical mines and prospective drillholes of its own. Despite that fact there has been no drilling or surface exploration of any kind of in the last 16 years.

The overall geologic framework of the Project makes it is prospective for multiple styles of deposits: a wedge of extremely deformed, altered and veined sediments is sandwiched between the boundaries of two large intrusions, which introduced high temperature, metal-rich fluids into the deformed sediments (Figure 3, 4, 5) (Shawe, 1986). Huge, caldera-forming volcanic eruptions occurred millions of years later (Shawe and Snyder, 1988), setting the stage for lower temperature magmatic-hydrothermal systems which are the likely source of the gold-rich fluids that mineralized the Round Mountain deposit. Magmatic-hydrothermal fluids from the same event are likely sources for the high grade epithermal veins on the western portion of the Project (Ervine, 1973; Shawe, 1986). The combination of such significant magmatism at different times in this region led to the creation of a metal rich environment: gold (Au), silver (Ag), antimony (Sb), mercury (Hg), copper (Cu), lead (Pb), molybdenum (Mo) and tungsten (W) have been targeted and variably mined, usually by companies focusing solely on one commodity or one prospect. The Company is the first to explore the Property as a whole in an attempt to put into context the metal zonation observed and what the precious metal potential could be in such a system (Figure 6). 

Target Geology – Lithology, Structure, Alteration

Host rocks at Spanish Moon are comprised of Paleozoic shale, siltstone, limestone and quartzite. These form a westward terminating prism that is wedged between two younger granitic plutons and thickens from west to east. A shallowly dipping, northward verging thrust fault brings older schists atop the mineralized strata along the southern edge of the Property, obscuring potentially mineralized host rocks. Overlying the Paleozoic host rocks to the north and south of the district are younger rhyolite flows from three proximal volcanic calderas. The margins of the Meadow Canyon caldera transect the eastern edge of the host rock package, near the Flower target.  

Precious metal mineralization within the Project is marked on either end by the historic Barcelona silver mine at the west and the Flower mercury and antimony prospects to the east. At the center of the mineralized trend is the largest historical silver producer; the Barcelona mine, as well as the epithermal, gold-dominant Antone Canyon target. Reports note that mineralization follows a near linear west to east distribution and is zoned. On the western edge of the Property; higher temperature metamorphism, alteration, and mineralization forms W-Mo-Au-Ag-Pb skarns and to the east lower temperature Au-Sb-Hg veins and replacement beds are prominent (Ervine, 1973). The Company’s technical team interprets there to be a temporal as well as spatial relationship between silver veins, likely formed by low to moderate temperature replacement of earlier skarns, and historical Hg mines found at either end of the Property. This relationship suggests that multiple stages of mineralization occurred by overprinting and remobilization of metals. Such an interpretation seems feasible given the numerous magmatic events that have affected this wedge of host rocks through time. The technical team’s interpretation of Phase I results have, in part, verified the historical reports of metal zonation found in the area. 

Historic Exploration

There is no record of any significant modern precious metal exploration except at the Antone Canyon target, where Freeport-McMoran (1983-1985), Royal Standard Minerals with JV partner North Mining Corp. (1996–2000), and Golden Spike/Bullion River Gold/Antone Canyon Mining collectively took 1000 soil samples, completed 19 trenches totaling 5088 meters, and 63 drill holes for a total of 6430 meters (Figure 7) (DeMatties, 2003; Larsen, 1998; Margolis, 2004). The majority of this work focused on finding Carlin-style, sediment-hosted gold deposits in silty limestones (Freeport-McMoran); however subsequent junior companies targeted high grade veins but, facing low gold prices and lack of funding, were never able to expand on their successful trench and drill programs. New exploration results at the Antone Canyon target reveal a gold in soil anomaly over 1.5 kilometers long that will be the focus of the Company’s exploration efforts for this target. The Company intends to drill step out holes on the highest value intercepts.

The Company’s Phase 1 Exploration Results

For the first time in the history of this metal rich project, the Company has completed an extensive rock and soil survey across the entire the Spanish Moon District, which includes: 1) a >1 ppm Ag-in-soil (+/-Au) anomaly extending from west to east across the property and, 2) results from bedrock, small prospect pits, and the millsite returned values as high as 8520 g/t Ag and 10 g/t Au. 

Results from the Phase I sampling and mapping program suggest that there are three distinct and strongly mineralized domains at Spanish Moon; the western Barcelona, the central Antone Canyon and the eastern Flower domain (see Figure 3). The western domain appears to be an intrusion related silver and gold system forming the Barcelona target (Figure 8, 9). The central domain may be a low sulfidation and sediment-hosted gold and silver system forming the Antone Canyon target. The newly identified eastern domain could be a low sulfidation epithermal gold system forming the Flower and Meadow Canyon targets (see Figure 2). These three domains combined make the entire Spanish Moon District prospective for precious metals. At each of these targets, the strike lengths of known or newly discovered precious metal occurrences have been extended by >1 km. The technical team continues to find high grade Ag and Au at the surface in the Barcelona mine and Antone Canyon target areas. Additionally, the Company identified the presence of Au mineralization in the Flower-Meadow Canyon target, a prospect with no known exploration or sampling for Ag or Au.

Results from an extensive soil survey suggest that silver is anomalous across nearly the entire length of the property where typical Ag background values are 0.2 to 0.3 ppm. This silver anomaly occurs within a prospective limestone unit that is capped by a regional thrust faultThe same prospective limestone is the primary host rock to the neighboring historic silver-gold districts of Belmont (>10 Moz Ag produced 1868-1887) and Manhattan (>135k oz Au and >50k oz Ag produced 1906-1921). Compartmentalization of the local thrust fault architecture defines the boundaries of the three mineralized domains from west to east. 

Barcelona Target

The Barcelona Target is centered on a historical high-grade silver mine that produced approximately 200,000 ounces of silver between 1871 and 1922 at a reported grade ~25 oz/t Ag from quartz veins that overprint skarn mineralization (Hunt, 1936). Significant exposures of lower silver grade (15-20 opt), were reported to have been left in the ground due to the high cost of milling and transportation and low silver prices at the time of production (Fletcher, 1907; Hunt, 1909). 

At the historic Barcelona mine area, soil and rock results extend the area of identified silver mineralization west, creating a high-grade silver domain in the western third of Spanish Moon. Samples from small mine dumps and prospect pits at Barcelona delivered assays up to 1590 and 1310 g/t Ag. Rocks from the mouth of a collapsed drainage tunnel and a former mill site at Barcelona delivered values of 884, 688, and 230 g/t Ag. Outcrops and decline rock samples in and surrounding the historic mine portals delivered silver values up to 235 g/t Ag over a 0.3 m width, 177 g/t over a 2.7 m width and 141 g/t Ag over a 1.2 m width. 

Antone Canyon Target

The Antone Canyon Target is characterized by a weakly metamorphosed, silty limestone that hosts high grade epithermal style gold mineralization and has been encountered in drilling, trenching, and rock chip sampling programs (DeMatties, 2003). 

Phase I results have tripled the strike length of Au mineralization identified at Antone Canyon; extending the occurrence by 1 km to the west of known mineralization. Rock samples from small prospect pits and outcrops delivered Au assays up to 10.2 g/t, 9.9 g/t, and 8.0 g/t. The newly identified western two thirds of the Antone Canyon gold anomaly has never before been drill tested and mapping suggests mineralization is focused immediately beneath the thrust fault contact. Reconnaissance mapping efforts further suggest subsidiary normal faults may influence smaller pods of mineralization internal to the three primary domains. For instance, follow up mapping and sampling outside known mineralization identified multiple outcrops and prospects where the rock characteristics are analogous to Antone Canyon mineralization, with features of both low sulfidation epithermal (eg. banded quartz veins) and sediment-hosted (eg. sulfides in sedimentary rocks) gold and silver mineralization. The greatest density of mineralized samples and highest gold concentrations occur where the north-south oriented Hooper fault intersects the Barcelona thrust fault. This area of intersecting structures is minimally drilled and represents a primary target area for the Company (Figure 10). The next step at Antone Canyon includes a geophysical survey to define new drill targets. In addition, relogging legacy core from Antone Canyon will offer insight as to whether mineralization has a structural or stratigraphic control. 

Flower – Meadow Canyon Target

At the eastern end of the district, the Flower target is characterized by a mercury and antimony occurrence may represent the higher levels of an epithermal system correlative with underlying precious metals. This target had never been explored for precious metals despite mercury and antimony being known distal indicators of epithermal gold mineralization at depth. 

Results of the soil survey in the Flower domain identified a large As, Sb, Tl, Hg, La, and Pb anomaly covering approximately a 2 km(Figure 11). These soil anomalies are accompanied by surface rock samples containing up to 1.2 g/t Au. Reconnaissance mapping suggests the anomalous geochemistry may correspond with steeply dipping normal faults associated with a regional fault that forms the eastern margin of an adjacent caldera. Building on this reconnaissance mapping the Meadow Canyon conceptual target was developed by combining components of regional structural interpretations, regional USGS geochemistry (Shawe, 2003), and cohesive arsenic-antimony-mercury-thallium anomaly from Eminent’s Phase 1 rock and soil geochemistry programs. Most of the significant gold and silver mineral occurrences in the region are epithermal in nature and are associated with Tertiary-age volcano-magmatic activity and similar geochemical signatures. Additionally, the mineralization occurs where the following features are present: 
1) within a >1,000 ppm As anomaly, 2) on or immediately adjacent to an Oligocene-age basin-bounding fault, 3) adjacent to a caldera. 

The largest gold and silver system in the region is the world-class Round Mountain deposit (20 Moz of gold produced), which occurs on a subsidiary structures linking the main caldera bounding faults. A similar structural setting exists at the Meadow Canyon Target where the Jefferson Canyon fault links to the Meadow Canyon fault. Multiple known epithermal vein systems occur along the strike of the Jefferson Canyon fault (i.e. Kinross’ Gold Hill deposit and Gold79’s Jefferson Canyon deposit) before the fault is obscured by post mineral cover where it links to the Meadow Canyon fault. Eminent’s 2021 soil sampling identified a large body of strongly correlated pathfinder elements indicative of a low sulfidation epithermal system (As, Hg, Sb and Tl) that coincides with intense silicification of basement rocks. The anomalous pathfinder geochemistry and alteration is open to the north where it becomes obscured by thin veneer of younger volcanic rocks. This region north of the Flower Target area was added to the Spanish Moon land package. 

A preliminary soil survey at Meadow Canyon consisted of several north-south and east-west oriented lines of soil samples spaced at 100 m, obliquely crossing the targeted structures to test if they were pathways for ascending geochemically anomalous groundwaters. Initial results vectored northward from Flower to the Meadow Canyon target where post-mineral volcanic cover up to 150 m thick obscures surface expression of the target. Volcanic cover consists of Late-Oligocene to Early-Miocene volcanic material that post-date or potentially overlap the timing of mineralization at Round Mountain and adjacent gold deposits (i.e., Gold Hill and Jefferson Canyon). Due to the volcanic cover, Eminent Gold did not anticipate any gold in soil values above 10 ppb (background is 0.01 to 1 ppb). Discovery of a suite of epithermal gold pathfinder elements that correlate within Meadow Canyon as well as some gold, through the post-mineral cover, is highly encouraging in this conceptual target. This initial soil survey returned multiple samples >10 ppb and up to 232 ppb which gives Eminent Gold reason to believe there is potential for a significant buried gold system. In addition, three out of five of the samples carrying gold occurred immediately adjacent to one of the two targeted feeder faults suggesting gold leakage occurred at a location where potential gold mineralization would be anticipated.

The structural block defining the Meadow Canyon target has never been tested. The Soldier Springs fault is the reactivated western margin of the Meadow Canyon caldera and has regularly ruptured up to present times. The ongoing fault ruptures are inferred to influence the vertical ascent of groundwater carrying pathfinder geochemistry upwards through post-mineral cover. Scavenging and transport of pathfinder elements to the surface from mineralized rocks at depth would have occurred along these faults, resulting in the anomalies presented here. Positive results of the preliminary soils demonstrate that correlative arsenic, antimony, mercury, thallium, and gold extends from the Flower target in the south to the northern limit of the Meadow Canyon target. Several rock samples with <1.2 g/t gold are interpreted to represent the distal expression of the low sulfidation epithermal target at Meadow Canyon.

The Company’s Phase 2 Plans

The Company is collaborating with an industry leading permitting agency to advance the project’s Plan of Operations permit with the US Forest Service. Permitting steps are being taken while also planning a project wide geophysics program for the 2022 field season. Positive results from this preliminary soil survey validate the team’s conceptual model and the need to complete a soil grid across the entire Meadow Canyon claim block in concert with a geophysical survey. An isometric soil grid will provide clarity as to where the most reasonable buried target exists in the Meadow Canyon area (Figure 12). A geophysical survey will define the thickness of the volcanic cover sequence as well as the architecture of the inferred linkage faults. The geophysics program will be designed to image the multiple styles of mineralization in all three target areas of Spanish Moon; 1) intrusion related silver and gold at the Barcelona Target, 
2) epithermal/sediment-hosted gold and silver at the Antone Canyon Target, 3) epithermal gold and silver at the Flower-Meadow Canyon Target. Geophysics will enable our technical team to refine drill targets for each Target Area to be tested in the fall of 2022.
