INFINITY DEFINES SIGNIFICANT GOLD TARGETS AT THE
BARLOW'S GULLY GOLD PROJECT
Highlights:
- Rock chip sampling at the Barlow's Gully Gold Project in the Central Goldfields, Western Australia, has returned up to 15.5 ppm Au.
- Subsequent aircore drilling and soil sampling across the Barlow's tenement has defined three significant gold targets - the largest being 480 x 100 m in area.
- The three soil/aircore anomalies contain anomalous levels of gold up to 0.681 ppm Au.
- RC drilling is planned in the next few months to test these high-priority geochemical targets.
Infinity Mining Limited (ASX: IMI) (the Company or Infinity) is pleased to announce the discovery of three significant aircore/soil gold anomalies at their Barlow's Gully Gold Project (Barlow's), in the Central Goldfields of WA.
The Barlow's tenement (P37/8278) is located in the Leonora Gold Mining District of the Central Goldfields. The project lies within an Archaean greenstone belt along the Ursus Fault Zone, which is also host to several significant gold deposits along strike to the SSE, such as King of the Hills and Kailis (see Figure 1).
Numerous historical shallow workings and prospecting pits occur at Barlow's. Until Infinity's involvement, the licence was held in private hands for many years and has not seen any modern-day exploration.

Mapping and Rock Chip Sampling
Infinity carried out reconnaissance geological mapping and a rock chip sampling program across the Barlow's tenement in early 2022. A total of 8 rock chip samples were collected, largely from quartz veins at surface. Three of the eight rock chip samples returned high-grade gold assays over 1 ppm Au, with the highest assay being 15.495 ppm Au (see Table 1).

Aircore Drilling and Soil Sampling
After confirming high-grade gold in surface rock chip samples, a program of aircore drilling was completed by Infinity on the eastern side of the Barlow's tenement where some alluvial cover is present overlying the Archean greenstones. A total of 194 aircore holes were drilled along 150 m to 200 m spaced North-South lines, with drill sites every 25 m spacing along the lines. Holes were inclined at 60 degrees to the north, roughly perpendicular to the bedding foliation, and drilled to the Archaean greenstone basement. Drill hole depth ranged from 1 to 22 m. At each drill hole, a 1 m thick, end of hole sample was collected for analysis. A drill hole collar table with end of hole gold assays is included as Appendix 1.
A soil sampling program was then completed by Infinity on the western side of the Barlow's tenement, where cover is thinner and basement outcrop is partially exposed. Soil samples were collected along 100 m spaced North-South lines, with a sample collected every 50 m along each line. A total of 220 soil samples were collected largely from the C-horizon soil layer. A soil sample site location table with gold assays is included as Appendix 2.
The aircore samples were submitted to Jinning Testing Laboratory in Kalgoorlie, and the soil samples were submitted to ALS Kalgoorlie for gold analysis by fire assay. Details of these programs are included in a JORC (2012) Table 1, attached with this document.
Gold assays for the aircore drilling and soil sampling programs returned highly anomalous results up to 0.681 ppm Au (see Tables 2 and 3). The gold assay results have defined three significant east-west trending gold anomalies of greater than 0.1 ppm Au (see Figure 2). The largest gold zone is 480 m long and 120 m wide.

Interpretation
The Barlow's tenement lies along a major shear zone associated with the Ursus Fault Zone (see Figure 1), which is cut by a number of secondary cross-cutting structures.
The largest anomalous gold zone at Barlow's (Anomaly 1), is 480 m long and 120 m wide and represents a significant size target for drill testing. Anomaly 1 is also coincident with a magnetic anomaly, which is likely to be associated with a granitoid intrusion, (see Figure 2).

Forward Plan
A program of RC drilling is being planned by Infinity on the Barlow's Gully Gold Project (P37/8278). Infinity intends to carry out a program of inclined RC drilling, angled underneath the three anomalous gold zones, to test for structurally hosted gold mineralisation.
The three highly anomalous gold targets (Anomalies 1 to 3) have never been drilled in the past by previous explorers. Infinity is planning to drill test these anomalies in the coming months.
