ANT BACKGROUND
ANT is a passive ground geophysics method that uses natural or man-made seismic noise as a signal source to measure the seismic velocity of the subsurface in three dimensions. During an ANT survey geodes are place in the ground on a regular grid and record the passive seismic noise over a period of time. Depending nature of the seismic noise, this can take several days, after which the geodes are moved to new sites on the grid.
Once the survey is completed a 3D shear wave (S-wave) velocity model of the ground under the grid is made and in the case of IM's Woody Prospect used to identify potentially sizeable lithium bodies at depth. These larger concealed pegmatite bodies are the roots to the currently exposed pegmatite dykes (Figure 2) and should appear as low S-wave velocity zones due to their lower rock density relative to the surrounding denser greenstones.

THE SURVEY
At the Woody Project, the ANT survey covered the entire tenement E45/4848 and the southern portion of E45/5720.

==> picture [595 x 112] intentionally omitted <==
The grid layout focused on specific areas based on previous findings:
-
Western Grid (200m x 200m) : Over Li-bearing pegmatite outcrops.
-
Eastern Grid (200m x 250m) : Focus on concealed targets without known pegmatites.
-
NW Infill Grid (100m x 100m) : Over prior lag rock chip survey areas showing anomalous LiRb-Cs geochemistry and extending south.
An additional grid was established in southern E45/5720 to extend exploration along the northeast trend of pegmatite dykes.
Figure 3: ANT survey node distribution.
RESULTS
Results from the ANT survey were converted into a 3D block model using a kriging extrapolation orientated to the regional NNE geological trend and near vertical dip of the geological units (see Figure 4)

Figure 4. 3D ANT S-wave velocity model with draped magnetics, geology and IM's drilling.
Analysis of the 3D model incorporating 3D magnetic inversions, ground gravity, surface geology and geochemistry and IM’s existing drilling identified 7 Targets. The targets are relatively flat lying concealed zones of low density which cut through the steeply dipping stratigraphy, see Figure 5 and Figure 6. The targets also lie below the base of weathering which is easily identified in the seismic data. Exact depths and thicknesses of the targets are different to quantify as their interpretation is based on varying low speed S-wave velocities.

TARGETS
Two of the target zones, Target 1 and 2, lie directly below mapped outcropping lithium bearing pegmatites and IM’s drilling, which intersected spodumene bearing pegmatites dykes at depths, see Figure 5.

Figure 6. Targets zones with 3D faulting, mapped pegmatites and IM's drilling.
Target 1
Target 1 is situated within the Euro Basalt along the boundary between a basalt unit and a felsic schist unit, extending approximately 1.2 km north from the Naughton Prospect. The top of this target is estimated to be between 100m and 200m below the surface, as shown in Figure 7. Below the Naughton Prospect drilling, the target extends to approximately 350m in what may be a feeder structure. Thicknesses vary from 30m to 100m. The host basalt exhibits a strong magnetic response along strike from the prospect, which has been disrupted within the target zone. The less magnetic felsic schist to the east also shows subtle magnetic destruction.
Target 2
Located at the northern end of the central ultramafic (komat te) unit of the Euro Basalt, Target 2 exhibits magnetic signature destruction in the komat te unit. The target lies just below the 2022 RC drilling at the McNeill Prospect (see Figure 7) and measures approximately 350m by 300m, with a thickness of around 40m. It also extends to roughly 350m below the Naughton Prospect drilling area, possibly in a feeder structure.

Target 3
Targets 3 lies at the southern end of the tenement within felsic schists of the Euro Basalt where they are faulted up against the central komat te unit. The target is approximately 500m by 150m and 60m thick and dips at ~45[o] to the north, with the top of the body at the southern end being approx. 60m below the surface and northern end approx. 250m below, see Figure 8. There is possible magnetic destruction in the area however this is overshadowed by strong magnetic response of the adjacent komat te.
Target 4
Target 4 lies within the central komat te unit and lies approx. 35m to 60m below the surface. It is approx. 700m long and up to 500m wide and 60m thick. No pegmatite dykes are exposed in these ultramafic rocks however they are tightly folded and faulted and maybe concealing pegmatites at depth. There is no evidence of strong magnetic destruction despite the body cutting roughly horizontal across the near vertical dip of the komat te units.

==> picture [595 x 112] intentionally omitted <==
Target 5
Target 5 is another large body that lies within basalts and schists of the Euro Basalt, on the eastern side of the komat te, where they are faulted up against rocks of the Apex Basalt. The body is approx. 850m long and up to 500m wide and lies roughly 70m to 130m below the surface, thanks to ~15[o] to the north. The area is also partially covered by alluvium and colluvium and displays magnetic destruction.

Target 6
Target 6 is approx. 300m long by 150m wide and up to 80m thick. The body lies roughly 150m below the surface between Targets 5 and target 7 and maybe related to the former, see Figure 9. It’s also located within basalts and schists of the Euro basalt which are partly covered by alluvium. The area shows magnetic destruction similar to that seen in Target 5.
Target 7
Target 7 lies in the central northern part of the tenement. The target is roughly 300m by 250m and the top lies approx. 130m below the surface. It is located within interbedded basalts and schist of the Euro Basalt. There is no evidence of pegmatites however the area is covered by recent alluvium and colluvium. The host basalts also show evidence of magnetic destruction which roughly lines with trends seen in the Target 2 area.

NEXT STEPS
Infinity Mining has planned two 300m diamond drill holes targeting the northern and southern ends of Target 1, with one hole positioned beneath previous Reverse Circulation (RC) drilling and surface sampling at the Naughton Prospect (see Figure 10).
The diamond core obtained will provide valuable insights into the geology and geochemistry of the Li pegmatites.
Additional exploratory holes are also planned to test other targets, with further detailed drilling contingent on these initial results.

Joe Phillips, Executive Chairman of Infinity Mining commented:
"We are thrilled with the results from our recent ANT geophysical survey which has not only identified high-priority lithium targets but also confirmed the effectiveness of advanced passive seismic technology in our exploration strategy. The ability to pinpoint subsurface structures indicative of larger concealed lithium pegmatite bodies gives us a significant advantage as we continue to build the project scale.
Dimond drilling is needed to gain a deeper understanding of these target zones. This next phase of exploration will provide invaluable geological data that will guide our ongoing exploration and contribute to Infinity’s growth in the lithium sector. To this end the company is seeking a venture partner to continue the journey Infinity Mining started in 2002."
