Assays for the 10 holes reported in this announcement have not been included in the MRE update and will be included in the next MRE update planned for Q4 2022
-
Assays are currently pending for a further 56 holes
Eagle Mountain Mining Limited ( ASX:EM2 ) (“ Eagle Mountain ”, the “ Company ”) is pleased to provide an update on its 100% owned Oracle Ridge Mine Project (“Oracle Ridge”, “Project”) in Arizona, USA.
Assays have been received for 10 drill holes, comprising six resource extension holes and four resource infill holes. Figures 2 and 3 illustrate the location of significant new results while Tables 1 and 2 summarise key intercepts.
Page 1
Eagle Mountain Mining CEO, Tim Mason, commented:
“The Western Talon has delivered some of the thickest and highest-grade intersections to date with mineralisation getting richer to the south. We are delighted that these results continue to add confidence to the historical drilling and demonstrate the Resource growth potential at Oracle Ridge.
The resource infill drilling is designed to allow us to declare Measured Resources for the first time under the JORC Code and increase tonnes in the Indicated category in the MRE update, which is scheduled for completion in a few weeks. Expanding the resource base in the Measured and Indicated categories is critical, as following completion of successful feasibility studies, we aim to translate these to Proven and Probable Reserves.
These exceptional results will be included in a further MRE revision later this year which will benefit from the strong results reported in this announcement plus all other assays received up to the time of finalising that revision. By that time, we are planning to have re-opened the existing mine and have an underground rig conducting infill drilling to increase the Measured and Indicated Resource with more efficient drilling. At the current and expected rate of drilling, we should have well over 100 new drillholes to be incorporated into that MRE revision.”

Resource Infill Results
Four holes were drilled in the north-west of Oracle Ridge (“main mine area”) as part of the Resource Infill program (WT-21-52, WT-21-55, WT-21-58, WT-21-60).
The main objective of this program is to integrate and confirm historical results and allow Measured Resources, the highest confidence level under the JORC Code, to be declared. All drill holes provided good support to nearby historical intercepts. Interestingly, mineralisation continued to be intersected between the main mineralised lodes in historically unsampled areas. While more work is required, these results are encouraging and could have favourable implications for reducing mining costs in a potential production scenario.
A second goal of the Resource Infill program is to collect samples for upcoming metallurgical studies. For this reason, some of the holes were drilled using a larger diameter drill bit to collect a larger sample more suitable for metallurgical testwork. A summary of key intercepts from infill drilling is outlined in Table 1 below.

WT-21-55
WT-21-55 was drilled in the main mine area as part of the Resource Infill program (Figure 2; Figure 5). This drill hole encountered significantly more continuous mineralisation than the adjacent historical holes.
The drill hole intersected a steeply dipping vein carrying significant copper sulphides (Figure 4). This represents the second time such a vein has been intersected in this area (see ASX announcement 24 January 2022) suggesting that, notwithstanding their limited thickness, these veins could be more widespread than originally thought. The current interpretation is that there is a “vein swarm” oriented perpendicular to the gently dipping skarn bodies in the area. Should this concept be confirmed by
Page 5
further exploration, these veins could significantly upgrade the volumes of sediment between the skarnhosted copper lodes which have previously been considered devoid of any significant mineralisation.
As can be seen in Figure 5, gaining access to the underground workings will assist exploration in these previously discounted areas.
Best intersections in WT-21-55 include:
- 17.3m fully diluted at 2.23%Cu, 25.34g/t Ag and 0.21g/t Au; including
o2.4m at 4.09% Cu, 28.76g/t Ag and 0.24g/t Au

Figure 4 – Section of core from WT-21-55 showing moderately altered sediments crosscut by strongly mineralised vein sub-parallel to the core axis. The extent and significance of this style of veining is not yet well understood, but its presence in multiple recent Resource Infill holes is highly encouraging. The vein was not the primary target of this hole which explains the sub optimal drill orientation (Depth 163.9 – 166m).

WT-21-58
WT-21-58 was an infill hole completed in the main mine area as part of the Resource Infill program, approximately 50 metres to the east of WT-21-55 (Figure 2, Figure 5). The drill hole intersected abundant skarn-hosted mineralisation confirming the results of historical drill holes in the vicinity. Only minor cross-cutting veins carrying Cu-sulphides were noticed. WT-21-58 was drilled using a larger diameter drill bit to obtain a larger sample size through mineralised zones. These samples will be used to complete metallurgical testwork later in the year. Key intersections from WT-21-58 include:
-
4.8m at 2.11% Cu, 20.18g/t Ag and 0.32g/t Au from 110.5m
-
5.4m at 1.85% Cu, 20.33g/t Ag and 0.23 g/t Au from 118.3m
-
6.9 m at 1.95% Cu, 28.86g/t Ag and 0.27 g/t Au from 136.1m
-
10.5 m at 1.95% Cu, 26.04g/t Ag and 0.28 g/t Au from 146.0m
The above intersections are contained within a broad fully diluted mineralised interval of 46.0m at 1.49% Cu, 17.91g/t Ag and 0.20g/t Au from 110.5m.
WT-21-52
WT-21-52 was an infill hole completed in the main mine area as part of the Resource Infill program (Figure 2, Figure 6). The drill hole intersected abundant skarn-hosted mineralisation confirming the results of historical drill holes in the vicinity. Key intersections from WT-21-52 include:
-
14.2m fully diluted at 2.40% Cu, 28.45 g/t Ag and 0.36 g/t Au from 111.3m including
o2.0m at 4.94% Cu, 64.79 g/t Ag and 0.57 g/t Au from 119.3m -
0.9m at 7.49% Cu, 153.00 g/t Ag and 1.11 g/t Au from 129.9m
-
9.0m at 2.07% Cu, 26.47 g/t Ag and 0.25 g/t Au from 133.5m
-
46.7m fully diluted at 1.78% Cu, 20.82 g/t Ag and 0.23 g/t Au from 111.3m including

WT-21-60
WT-21-60 was an infill hole completed in the main mine area as part of the Resource Infill program (refer Figure 7) and intersected abundant skarn-hosted mineralisation confirming the results of historical drill holes in the vicinity. The hole was terminated after drilling through an underground drive but still tested its primary targets. As for WT-21-58, WT-21-60 was drilled using a larger diameter drill bit to collect a larger sample size through mineralised zones. These samples will be used to complete metallurgical testwork later in the year. Key intersections from WT-21-60 include:
-
4.8m at 1.94% Cu, 26.97g/t Ag and 0.33g/t Au from 25.9m
-
7.2m at 2.04% Cu, 31.81g/t Ag and 0.60g/t Au from 35.8m
-
6.7m at 2.93% Cu, 28.03g/t Ag and 0.52g/t Au from 49.7m
-
10.9m at 2.45% Cu, 18.97g/t Ag and 0.41g/t Au from 59.1m
The above intersections are contained within a broad fully diluted mineralised interval of 44.1m at 1.64% Cu, 17.58 g/t Ag and 0.32 g/t Au from 25.9m. A deeper mineralised zone was also encountered:
- 13.1m at 2.07% Cu, 17.47g/t Ag and 0.31g/t Au from 159.7m (this hole ended in mineralisation with the drill hole piercing an underground drive)

Selected historical results above 1% Cu are shown in grey for clarity (refer ASX announcement 25 May 2020). WT-21-60 terminated in mineralisation at the lower underground workings.
Resource Expansion drill holes
Six holes were drilled as part of the Resource Expansion program. Hole WT-21-75 was drilled just to the south of the main mine area and confirmed mineralisation at the Leatherwood-Sediments contact extends to this area. Five holes (WT-21-53, WT-21-54, WT-21-56, WT-21-57, WT-51-59) were drilled in the Western Talon. Results from these holes continue to confirm the interpreted geological model and suggest that the:
-
Stacked mineralised lode extends further to the north than previously interpreted (WT-21-53)
-
Mineralisation grade and thicknesses show an increase to the south with recent results in WT21-56 and WT-21-59 returning some of the best intersections at the Talon to date.
A summary of key intercepts from Resource Expansion drilling is outlined in Table 2 below.

WT-21-75
WT-21-75 was drilled in a poorly explored area at Oracle Ridge, between the main mine area to the north and the central mine area to the east and south. Mineralisation in this part of the mine is located along the Leatherwood-Sediments contact with the Company having drilled several holes in this area to test continuity of mineralisation in the area.
WT-21-75 is the first one of this series of holes where assays have been received. Two zones of mineralisation near the contact were encountered with similar grade and thickness to historical holes in the vicinity (Figure 8):
-
5.2m at 1.04% Cu, 11.06g/t Ag and 0.15g/t Au from 159.8m
-
3.9m at 2.04% Cu, 14.32g/t Ag and 0.42g/t Au from 169.4m
Mineralisation remains open to the south, east and west with results from recent holes in this area still pending.

WT-21-53
WT-21-53 was drilled at the northern end of the Talon approximately 60 metres to the north of WT-2150 (14.1m at 1.51% Cu, 12.06g/t Ag, 0.42 g/t Au; Figure 3, Figure 9). The drill hole intersected three mineralised zones:
-
An upper zone returning 14.8m at 1.74% Cu, 13.98g/t Ag and 0.33g/t Au from 266.2m.
-
A middle zone with scattered intersections over 30 metres starting from approximately 290m downhole and including 1.4m at 1.88% Cu, 14.65g/t Ag and 0.29g/t Au and 4.7m at 1.54%Cu, 12.60g/t Ag and 0.22g/t Au.
-
A lower zone of 9.6m at 1.99% Cu, 13.14g/t Ag and 0.10g/t Au within a larger 15.1m zone at 1.55% Cu, 11.39g/t Ag and 0.08g/t Au using a lower 0.6% Cu cut-off. This is hosted within the Leatherwood with mineralisation hosted in quartz veins and fractures with abundant copper sulphides (chalcopyrite and bornite).
The results from WT-21-53 are encouraging and suggest that multiple stacked mineralised zones may extend from the Talon to the north towards the central mine area. Presence of mineralisation within the Leatherwood is also anomalous and the technical team will review the intersection in WT-21-53 in detail to better understand this style of mineralisation and its potential extensions.
Page 11
Three holes have been completed in the vicinity of WT-21-53 and WT-21-50 with further assays pending (Figure 9).

WT-21-54
WT-21-54 was drilled in the Central Talon (Figure 3 and Figure 10) approximately 70 metres east of WT21-44 (61.5m fully diluted at 1.07%Cu, 9.87g/t Ag and 0.14g/t Au), 50 metres south of WT-21-38 (1.6m at 5.23% Cu, 2.42g/t Ag) (refer ASX announcement 1 December 2021) and 60 metres north of WT-2156 (Figure 10). The drill hole intersected multiple narrow mineralised zones over 80 metres including:
-
2.9m at 1.61% Cu, 16.18 g/t Ag, 0.19g/t Au from 190.6m
-
7.0m at 1.17% Cu, 10.48 g/t Ag, 0.19 g/t Au from 213.5m
-
2.7m at 2.38% Cu, g/t Ag, 24.34, 0.66g/t Au from 274.9m
In an east-west direction, the mineralisation intensity increases towards the west with grade and thickness increasing as the Wave is approached. In a north-south direction, this area of the Talon shows an increase in mineralisation grade and thickness from WT-21-38 to the north, through WT-21-54 and continuing to WT-21-56.
Page 12
WT-21-56
WT-21-56 was drilled in the Western Talon, approximately 50 metres east of WT-21-25 (9.1m at 2.39% Cu, 22.47g/t Ag and 0.22g/t Au, Figure 3, Figure 10). The drill hole intersected a very thick high-grade zone containing several richer intervals. Results include:
-
30.7m at 2.54% Cu, 21.84g/t Ag and 0.42g/t Au from 207.9m
-
12.7m at 1.13% Cu, 9.14g/t Ag and 0.13g/t Au from 242.7m
-
8.7m at 2.19% Cu, 19.22g/t Ag and 0.39g/t Au from 262.3m within
-
63.1m fully diluted at 1.84% Cu, 15.68g/t Ag and 0.30g/t Au from 207.9m
A review of the mineralisation and structural data shows some variability in the orientation of the stratigraphy suggesting that folding could explain the thicker mineralisation seen in this hole.

Page 13
WT-21-59
WT-21-59 was drilled in the Western Talon (Figure 3, Figure 12) 50 metres east of WT-21-45 (74.4m fully diluted at 0.93% Cu, 6.92g/t Ag and 0.10g/t Au). The drill hole intersected two main mineralised zones: an upper zone above the Wave (Q-Sill) and a thicker, higher-grade zone just below the Wave. Sediments in the lower part of the hole are only locally mineralised.
Throughout WT-21-59, bedding has a more consistent orientation than drill hole WT-21-56, approximately 60 metres to the north. The main mineralised zone shows an increase in variability again possibly linked to folding or other structural disruptions such as faulting.
Key results include:
Upper zone
-
11.0m fully diluted at 1.35% Cu, 10.61g/t Ag and 0.51g/t Au
-
Main zone
-
38.1m fully diluted at 1.97% Cu, 20.64g/t Ag and 0.51g/t Au including
o8.9m at 2.66%Cu, 25.83g/t Ag and 0.66g/t Au-
11.0m at 2.55% CU, 28.84g/t Ag and 0.81g/t Au
-
2.8m at 4.73% Cu, 48.83g/t Ag and 1.04g/t Au
-
WT-21-59 contains some of the best gold grades encountered at the Talon and throughout the Project confirming the interpreted trend which has gold content increasing towards the south.

Next steps
The Company is finalising an updated JORC Mineral Resource Estimate (MRE) to be released this month. These latest results have missed the cut-off date for the updated MRE and will be included in a further MRE revision planned for Q4 2022.
The Company has recently announced the planned reopening of the underground at Oracle Ridge. Access to the existing mine development will provide significant benefits for resource infill drilling and metallurgical testwork. The shorter drill holes will assist in more efficiently converting Indicated Resource to Measured and Inferred Resource to Indicated compared to surface drilling. Several of the historical developments were completed in mineralisation and will allow the collection of bulk samples for metallurgical studies directly from underground.
Drilling will continue to focus on resource extensions at the Talon and in the northern Mine Area. The Company is expecting to receive permits to allow drilling at OREX in the coming months, following which a greenfields exploration program at this exciting target is planned to commence. This program will test the potential repetition of the skarn-hosted mineralised system at Oracle Ridge below the Leatherwood

intrusion. This target has the potential to substantially increase the resource base of the Project in the medium to long term.
Assay results for 56 holes are pending with 44 holes from the resource expansion program, 1 hole from the Resource Infill program and 11 holes from the maiden drill program at Golden Eagle.

•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 | ||
| was later expanded to approximately 1,000 short ton per day. | ||
| •The mine closed in 1996. Production records show that | ||
| approximately 1,200,000 short tons were milled since | ||
| commencement of the 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 scale 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 | ||

| •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. | ||

| 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” | ||
