High-Grade Assays 64g/t Au, 445g/t Ag and 15% Pb in Outcrop Enhance Porphyry Potential at Silver Mountain
Highlights
-
New high-grade gold, silver and lead assay results include:
-
64g/t Au, 445g/t Ag and 15% Pb across 0.5m vein
-
30.4g/t Au across 0.2m breccia zone
-
11.65g/t Au, 67g/t Ag and 3% Pb grab sample

Evidence of porphyry and porphyry-related mineralisation from new mapping and sampling, including:
-
High-grade zones with phyllic alteration
-
Prospective structural orientations
-
High-grade assay samples along a trend greater than 1 kilometre connecting historical mines

-
Further field work to follow up these high-grade trends is in progress
-
Elevated uranium, thorium and rare earths support potential for a U/Th/REE system at depth, with results including:
-
567ppm U3O8 and 2,276ppm ThO2
-
2,024ppm total rare earth oxides
Commenting on the new mapping, assays and next steps, Eagle Mountain Mining’s CEO, Tim Mason, said:
“We are excited to be discovering a stable of high-quality targets within this underexplored, world-class mining jurisdiction. These targets are supported by the discovery of high-grade gold and silver-rich zones along significant geological trends, including one stretching well over 1km between historic mines. Sampling and mapping results suggest the high-grade features could be porphyry related mineralisation. These exceptional results complement our previously identified porphyry indicators. New outcrops of porphyry alteration have been identified, adding to all the other indicators of a porphyry system under cover."

Eagle Mountain Mining Limited (ASX: EM2 ) ( Eagle Mountain , or the Company ) is pleased to provide an update on the Company’s 100% owned Silver Mountain Project ( Silver Mountain , or the Project ) in Arizona, USA.
Silver Mountain is located on the Laramide Arc, a northwest-southeast trending geological feature containing world-class porphyry copper mines such as Bagdad, Miami and Resolution in Arizona. It also lies on the southern extension of a northeast-southwest prospective metallogenic belt that hosts the United Verde and Iron King volcanogenic massive sulphide ( VMS ) historical mines (refer to Figure 1).
==> picture [507 x 367] intentionally omitted <==
Figure 1 – Location of Silver Mountain and surrounding deposits in Arizona USA, showing regional-scale porphyry and VMS corridors.
A recently completed field program has identified high-grade features such as mineralised quartz veins and breccias, as well as further porphyry alteration. The alteration supports the porphyry targets, defined previously and following the recent seismic survey (refer to ASX announcement dated 9 July 2024).

High-Grade Results Indicative of a Porphyry-Driven System
Assays up to 64.1 g/t gold, 445 g/t silver, and 15.4% lead (details in Table 1, Photo 1 and Photo 2) have recently been received from sampling of the north Scarlett area. These high-grade breccias and veins are situated between the Silver Dollar and Gold Hill mines, along a trend mapped over one kilometre in length (refer to Figure 2). Porphyry-driven hydrothermal activity believed to be the driver for the mineralisation supported by the observed alteration.
This area presents a compelling exploration target due to its strike length, structures and outcropping highgrade mineralisation which may support a stand-alone deposit.
An additional 500-metre-long trend was mapped further north near the historical Colossal mine (refer to Figure 2). Open strike extensions exist for both the Colossal and Silver Dollar-Gold Hill trends and provide further prospectivity beyond mapped areas.

==> picture [118 x 41] intentionally omitted <==
The recent high-grade results are encouraging particularly given that the field program was focused on alteration and structural data rather than specifically locating mineralisation.
Further field work is currently underway to establish the extent of mineralisation, alteration and structural extents.

Further Support for Porphyry Targets
Mineralised breccias and veins were mapped adjacent to the recent geophysically identified porphyry targets (refer to ASX announcement dated 9 July 2024). Broader sampling and mapping in the north Scarlett area indicated further porphyry alteration, supporting the prospectivity of defined porphyry targets concealed by younger Tertiary cover units, as shown in Figures 2 and 3.
Field observations at the Silver Dollar-Gold Hill and Colossal trends included phyllic alteration. At the Colossal trend, a phyllic overprint of propylitic alteration was also observed. These alteration styles are indicative of a possible porphyry system nearby.
It is significant to note that these trends, in addition to the most recently mapped base and precious metal features across north Scarlett, are proximal to the Breakaway fault zone. This fault zone is aligned to the prospective NW-SE Laramide Arc structural trend, a similar feature at surrounding porphyry deposits in Arizona (refer to Figure 4).
Recent mapping supports the interpretation that precious and base metal features are likely related to prospective Laramide activity, and possibly linked to a buried porphyry system, as shown in Figures 2 and 3.
There is further prospectivity related to a separate group of mineralised breccias within and around historical mines in the prospective NE-SW latite dyke trend at Pacific Horizon (as shown in Figure 4). These features may have also formed from hydrothermal processes, with additional field work aimed at confirming this geological concept.

Uranium Prospectivity in Pegmatites
A pegmatite sample collected during this field program returned 567ppm U3O8, 2,276ppm ThO2 and 2,024ppm total rare earth oxides ( TREEO ) as shown in Table 2. Continued elevated TREEOs in radioactive pegmatites are promising, given the known association between rare earths and uranium deposits (refer to ASX announcement dated 13 March 2024). Investigation into the extent and relationship between the pegmatites elevated in uranium and a possible porphyry-related system is ongoing.

Next Steps
Additional mapping and sampling is ongoing to delineate the full extent and grade of precious and base metal features, and how they could relate to a multi-mineralisation system concept.
A particular focus will be on structures interpreted to impact mineralisation, such as the Silver Dollar-Gold Hill and Colossal trends, in addition to the Breakaway, Ryland and Gold Note faults. A soil sampling program is planned to help establish the lateral extent of alteration zones. Analysis of rock samples to map pH and temperature zonation of the system is also planned to assist with vectoring towards a mineralising fluid and heat source. Further geophysical processing is nearing completion to create inversion models for the magnetics data.
