Thick Mineralised Zones, Previously Unrecognised 110m at 1.06% Copper, Hole ends in 3.6% Copper

  • Thick, fully diluted, mineralised zones within the existing JORC resource have been defined in recent infill drilling. Results include:

  • 110.1m at 1.06% Cu, 9.64g/t Ag and 0.16g/t Au (WT-21-24), ending in mineralisation

  • 106.0m at 1.15% Cu, 11.73g/t Ag and 0.16g/t Au (WT-21-20)

  • 96.1m at 0.98% Cu, 7.84g/t Ag and 0.15g/t Au (WT-21-18)

  • 47.3m at 1.00% Cu, 13.25g/t Ag and 0.13 g/t Au (WT-21-26)

  • WT-21-24’s thicker zone includes an outstanding:

  • 18.4m at 3.12% Cu, 27.83g/t Ag and 0.51g/t Au, within

    • 50.5m at 1.73% Cu, 14.31g/t Ag and 0.26g/t Au
  • Assays from historic holes focused on higher grade mineralisation based on visual identification with lower grade often left unsampled

  • These larger mineralised zones include both higher and lower grade material providing optionality and other benefits for potential future mining* including:

  • Planned mining dilution may include lower grade mineralisation providing additional marginal revenue

  • Higher throughput operation using a lower cut-off grade

  • Results anticipated to provide sufficient confidence to allow ‘Measured’ Resources to be defined in next MRE update in this area of the mine (highest confidence level for mineral resources under JORC Code)

  • Further Resource upgrade holes being planned to assess ongoing potential for thicker zones of mineralisation

  • Metallurgical testwork being planned to assess recoveries of thick mineralised zones

  • Assays pending for 18 further holes

*Note: No Pre-Feasibility or Feasibility Studies have been completed in accordance with JORC and no decision has been made on the commencement of mining at Oracle Ridge. There can be no certainty whether the results of any future technical and economic study will support the estimation of Ore Reserves or to provide assurance of an economic development case at this stage.

Eagle Mountain Mining CEO, Tim Mason, commented:

“These very thick zones of mineralisation have the potential to provide significant optionality for mining. We have now completed five infill holes, all of which had similar thick zones of mineralisation, suggesting that this may not be an anomaly. From a mining perspective, thick zones of mineralisation provide potential for bulk mining scenarios or using ore sorting technology to separate barren rocks from copper bearing ores to reduce processing costs. These results surprised us because many of these mineralised zones were not visually obvious in the core, and hence why they were probably not assayed by previous owners.

The intercept of 18m at 3.12% copper and 0.51g/t gold, within a much larger mineralised zone, is one of the best intercepts at Oracle Ridge. In addition, the overall gold grades in the reported infill holes are, on average, better than those in surrounding historical holes.

We are excited by these results, because if the presence of these thick zones is extensive it could materially improve the contained copper in resource and provide optionality for future mining methods and production rates.

We will continue with our program of resource upgrade drilling and given these latest results, we will certainly assay zones in between the key lodes!”

Eagle Mountain Mining Limited ( ASX:EM2 , “ Eagle Mountain ”, the “ Company ”) is pleased to provide an exploration update at its 100% owned Oracle Ridge Mine Project (“Oracle Ridge”, “Project”) in Arizona, USA.

Assay results for five drill holes have been received and are summarised in Table 1. Higher grade zones for drill holes WT-21-18 and WT-21-20 have been previously reported (ASX announcements 31 August 2021 and 29 July 2021) with the thicker mineralised zones reported herein.

Comparison with Historical Drill Holes

An important objective of the Resource Upgrade program was to verify the quality and reliability of historical drilling information in the Company’s database. The technical team has completed an initial comparison between new holes and historical ones in the vicinity. The comparison has shown a good reconciliation between old and new geological and assay data. The average gold grade in recent holes appears to be moderately higher than in historical ones.

Should the remaining infill Resource Upgrade holes support the grades and thicknesses of previous drilling, a portion of the existing Indicated Mineral Resource is expected to be upgraded to the JORC Measured category (following an updated Mineral Resource Estimate). Only ‘Measured’ Mineral Resources may be converted to ‘Proved’ Ore Reserves if they are economically mineable as defined by a Pre-Feasibility or Feasibility Study. These studies include the application of various modifying factors and dilution[1] . These studies have not been completed.

Commentary on Thicker Intersections

The Resource Upgrade program is targeting the thickest part of the existing resource, at the northwestern end of the Oracle Ridge mine. Mineralisation in this area is characterised by multiple stacked lodes separated by less endowed material. Historical drilling at Oracle Ridge was sampled with a strong bias towards high grade mineralisation, meaning that after a visual assessment, lower grade material was often left unsampled resulting in large intervals without any assay data.

During Eagle Mountain’s drilling, it became apparent that mineralisation, albeit of lower tenor than in the key lodes, is often pervasive throughout areas previously considered barren. Hence it was decided to sample all resource upgrade holes continuously across their entire length.

Table 2 provides a summary of the fully diluted thicker mineralisation within the five resource upgrade holes completed, including estimated true thicknesses.

These extensive intervals encompass high grade lodes and lower grade zones. These results are encouraging for several reasons:

  • Presence of mineralisation in volumes previously considered barren could increase the overall copper, silver and gold content at Oracle Ridge. Drilling will be required to obtain samples from areas that were previously unassayed due to much of the old core not being available. A material change in metal content is possible if a lower cut-off grade for the mineral resource is justified.

  • Reported thicknesses and grades could prompt a revision of the underground mining method envisaged at Oracle Ridge towards a less selective, bulk tonnage scenario.

  • Ore sorting technology may allow separation and disposal of very low grade and barren material prior to material being delivered to the mill.

A potential scenario involving a less selective mining technique, coupled with ore upgrading, could result in a lower cut-off grade being applied and a larger proportion of the copper, silver and gold in the current Mineral Resource Estimate (MRE) becoming minable. See Table 3 for a comparison of metal content in the existing MRE at different copper cut-off grades.

DRILL RESULTS

WT-21-24

WT-21-24 is the third hole completed within the resource upgrade program at Oracle Ridge (Figure 1, 2 and 3). The aim of this program is to allow the classification of Measured Resources, the highest confidence resource category under the JORC Code.

WT-21-24 was drilled approximately 25 metres to the east of WT-21-20 (Figures 1 and 2) and returned four significant intersections:

  • 18.4m at 3.12% Cu, 27.83g/t Ag and 0.51g/t Au from 53m

  • 4.1m at 1.44% Cu, 11.98g/t Ag and 0.12g/t Au from 74.7m

  • 17m at 1.17% Cu, 7.70g/t Ag and 0.16g/t Au from 86.5m

  • 3.4m at 1.86% Cu, 18.38g/t Ag and 0.30g/t Au from 118m

A full list of intersections above the 1% Cu cut-off grade is presented in Table 1 and Attachment 1.

WT-21-26

WT-21-26 is the fourth hole completed within the Resource Upgrade program at Oracle Ridge (Figure 1, Figure 7). WT-21-26 was collared approximately 140 metres from WT-21-24, targeting the northern end stacked lodes found in this part of the mine.

The drill hole returned the following significant intersections (above 1% copper cut-off grade):

  • 4.0m at 2.23% Cu, 21.01/t Ag and 0.28g/t Au from 111.5m

  • 4.3m at 2.22% Cu, 42.06/t Ag and 0.38g/t Au from 144.2m

  • 7.3m at 2.13% Cu, 31.84/t Ag and 0.35g/t Au from 151.5m

  • Within 14.6m @ 1.82% Cu, 30.31g/t Ag and 0.30 g/t Au from 144.2m

A thick zone of 47.3m at 1.00% Cu, 13.25g/t Ag and 0.13 g/t Au encompasses the above intersections from 111.5m.

A full list of intersections above the 1% copper cut-off grade is presented and Attachment 1.

WT-21-28

WT-21-28 is the fifth hole completed within the resource upgrade program at Oracle Ridge (Figure 1, Figure 7). WT-21-28 was drilled from the same pad and with the same orientation as WT-21-26 but with a steeper plunge.

The drill hole returned the following significant intersections (above 1% copper cut-off grade):

  • 1.8m at 1.66% Cu, 15.76/t Ag and 0.19g/t Au from 112.3m

  • 1.0m at 1.85% Cu, 16.05/t Ag and 0.19g/t Au from 117.0m

  • 3.5m at 2.69% Cu, 39.76/t Ag and 0.22g/t Au from 147.1m

  • 4.1m at 1.02% Cu, 10.20g/t Ag and 0.06g/t Au from 157.7m

A thick zone of 50.8m at 0.64% Cu, 7.49g/t Ag and 0.06g/t Au encompasses the above intersections from 111m (0.6% copper cut-off). The lower grades encountered in WT-21-28 are consistent with its location at the northern edge of the mineralisation in this part of the mine.

Next Steps

The Company’s three drill rigs are currently drilling at the Talon and Golden Eagle. The Resource upgrade drilling will resume as soon as the high priority targets in these areas have been tested. Ten holes have been planned with results reported for five of them to date. Upcoming Resource upgrade holes will be fully sampled to ensure assays are available for high grade and low grade zones alike. At least three of the outstanding holes will be drilling using larger diameter core (e.g. PQ size) to collect samples for upcoming metallurgical studies.

The delineation of thick mineralised zones has prompted a re-assessment of the metal content in between strongly mineralised lodes. A desktop review will be completed in the coming months to establish the potential of these lower grade zones to host significant mineralisation and the additional work required to unlock this potential.

In the medium term, further infill drilling from surface is planned to upgrade resources in the Inferred and Indicated JORC categories. Considering the proximity of many of these zones to the existing mine development, underground drilling could be more cost effective due to shorter hole lengths. The Company will evaluate the most appropriate time to re-establish underground access to enable underground drilling to commence.

done by other
parties
•The Oracle Ridge Mining District was discovered in 1873. In 1881, an
18 tonne per day copper smelter was erected at nearby Apache
Camp. The ore for this smelter was supplied from the Hartman,
Homestake, Leatherwood, Stratton, Geesman and other small mines
in the area.
•Phelps Dodge Copper Company (Phelps Dodge) entered the District
in 1910 and undertook considerable development and exploration
work.
•Continental Copper, Inc began exploring in the District in the 1950s.
Continental leased the property in 1968 with an option to purchase
and undertook a large exploration and development program. This
was the first time there was a large scale assessment of the
mineralisation.
•Union Miniere began a new exploration program in April 1980. In
1984, a feasibility study for an 1,814 short ton per day operation was
completed.
•In October 1988, South Atlantic Ventures acquired Union Miniere's
interest and entered into a 70-30 partnership with Continental to
develop the mine. Minproc Engineers Inc. was contracted to
supervise the confirmatory metallurgical test work. A detailed design
was started in November 1989 on a column flotation plant.
Construction of the facility commenced in April 1990 and the first ore
was processed through the plant on March 3, 1991. The capacity of
the mill was initially set at 771 short ton per day. The mill capacity
waslaterexpanded to approximately1,000 short tonperday.

Page 21

Criteria JORC Code explanation Commentary
•The mine closed in 1996. Production records show that
approximately 1,200,000 short ton were milled since commencement
of operation.
•Between 2009 and 2015 the project was owned by Oracle Ridge
Mining, a TSX-V listed company, which drilled approximately 130
surface and underground holes
Golden Eagle
•Small scall mining occurred in the Golden Eagle area in the first half
of the 1900s focussed on gold. The largest operation was the
Sanderson Mine. The mine is part of the Golden Eagle mineralised
system but is located outside the Company’s landholding. It reported
smelter returns between 1936 and 1941 averaging 0.4 Oz/short ton
Au (13.7 g/t Au), 0.65 Oz/ton Ag (22.3 g/t Ag) and 0.46% Cu (small
tonnage).
•Oracle Ridge mining conducted exploration at Golden Eagle in the
mid-1990s. A geophysical magnetic survey was flown over the area.
Few magnetic anomalies, postulated to be magnetite-rich skarn were
tested by reconnaissance drilling. Results were not deemed
sufficiently encouraging and no further drilling was conducted in the
area.
OREX
•Details of historical (pre-1980s) exploration and mining activities in
the OREX area are not known. Few small-scale workings were found
during mapping.
•In 1980 a Joint Venture between Gulf Minerals Corporation and W.R.
Grace Company completed mapping of the area and drilled 7 holes.
Results of the program were reviewed by Oracle Ridge Mining
Partners and summarised in an internal communication in 1992.
Red Hawk
•No historical exploration nor mining activities are known for the Red
Hawkarea
Geology Deposit type, geological setting and style of mineralisation. •The deposit is classified as copper dominated skarn. Minerals
representative of both prograde and retrograde skarn development
are present, the former being represented by diopside and garnets,
the latter by epidote, magnetite and chlorite.
•Copper dominated mineralisation generally contain chalcopyrite and
bornite. The deposits are most commonly associated with Andean-
type plutons intruded in older continental-margin carbonate
sequences. The associated intrusive rocks are commonly porphyritic

stocks, dikes and breccia pipes of quartz diorite, granodiorite, monzo-
granite and tonalite composition, intruding carbonate rocks,
calcareous-volcanic or tuffaceous rocks. The deposits shapes vary
from stratiform and tabular to vertical pipes, narrow lenses, and
irregular zones that are controlled by intrusive contacts.
•The copper rich skarn deposits at Oracle Ridge are found in
conformable lens along the contact with the Leatherwood
Granodiorite or associated with faults and shear zones which
intersect the Leatherwood. These have acted as feeders into the
reactive carbonate horizons. The latter can form a “Christmas Tree”
type shape.
