Inflection Resources Intercepts Porphyry Gold-Copper
Mineralisation in New South Wales
Vancouver, British Columbia, February 4, 202 5: Inflection Resources Ltd. (CSE: AUCU /
OTCQB: AUCUF / FSE: 5VJ) (the "Company" or "Inflection") is pleased to provide an update on
drilling completed in late 2024 on the Trangie and Duck Creek projects in New South Wales,
Australia conducted under an Exploration Agreement with AngloGold Ashanti Australia Limited
(“AngloGold Ashanti”) announced on June 14, 2023.
Summary Highlights:
• At Trangie, hole TRNDH023 has intersected the most significant gold mineralisation by the
Company to-date. The hole returned the following intercepts:
o 54.37m at 0.37 g/t Au and 0.07% Cu from 194.63m
▪ including 17.24m at 0.45 g/t Au and 0.09% Cu from 194.63m
▪ including 8.00m at 0.67 g/t Au and 0.11% Cu from 200.00m
▪ including 2.00m at 1.28 g/t Au and 0.12% Cu from 200.00m
▪ including 34.04m at 0.39 g/t Au and 0.07%Cu from 214.96m
▪ including 7.52m at 0.67 g/t Au and 0.10% Cu from 238.48m
o 35.47m at 0.40 g/t Au and 0.06% Cu from 259.53m
▪ including 25.47m at 0.46 g/t Au and 0.06% Cu from 259.53m
▪ including 6.00m at 0.53 g/t Au and 0.06% Cu from 259.53m
o 21.45m at 0.22 g/t Au and 0.04% Cu from 346.00m
▪ including 12.00m at 0.34 g/t Au and 0.04% Cu from 346.00m
• The mineralisation within TRNDH023 is associated with porphyry -style chalcopyrite-pyrite-
magnetite bearing quartz veins in biotite -altered andesitic volcanics. The style of
mineralisation and alteration is considered highly encouraging for the potential discovery of
better developed, higher grade mineralisation within the vicinity of this hole.
• Four step-out drill holes on the Duck Creek project totalling 3,124m were drilled in proximity
to the previously reported drill hole DCKDH020 (Inflection news release October 4, 2024) to
follow-up on inner propylitic, porphyry -style alteration with highly anomalous arsenic (As)
values. Hole DCKDH024 intersected the largest zone of inner propylitic alteration with
magnetite veinlets and assay values of 231m of >25ppm As from 389.65m and maximum gold
values of 2.00m of 0.12 g/t Au. The expanded zone of alteration and geochemistry suggests
a vector at depth to potential porphyry -style mineralisation between holes DCKDH024 and
DCKDH020, although the target is still open in several directions.
Alistair Waddell, Inflection’s President and CEO, states : “We are delighted to announce these
compelling drill results from our Trangie project which further validate the potential of our large
property portfolio in New South Wales. The discovery of broad zones of gold and copper
2
mineralisation, displaying classic characteristics of alkalic porphyry systems within the Macquarie
Arc, marks a pivotal milestone in our exploration program. These mineralized intervals are
particularly encouraging as they exhibit gold and copper grades consistent with the margins of
other significant porphyry deposits in the belt , strengthening our conviction in the project's
potential. The step -out drilling at Duck Creek has also significantly expanded the alteration
footprint discovered in drill hole DCKDH020, revealing a much-expanded target area that requires
systematic follow-up exploration.”
Trangie Project Drilling (Phase I):
In Q4 2024, a re-evaluation of the geochemical and alteration data from all holes drilled in New
South Wales to-date was completed. Hole TRNDH023 was designed after collaboration with
AngloGold Ashanti to follow up the porphyry related alteration and mineralisation intersected by
the first phase of wide spaced drilling previously completed at Trangie. This included hole
TRNDH010 which intersected anomalous gold mineralisation.
TRNDH023 was drilled in a westerly direction at a dip of -70º to a total depth of 393.00m to test
the central portion of an approximate 800m x 800m wide zone peripheral to earlier drill holes
TRNDH002 and TRNDH010 (Figure 1). Hole TRNDH023 intersected a significant zone of pyrite-
chalcopyrite bearing quartz veinlets and wispy magnetite veins in biotite -actinolite altered
andesites and volcaniclastic sediments , typical of a calc -potassic porphyry-proximal alteration
zone (Figures 3 and 10). The hole reported the following assay results:
o 54.37m at 0.36 g/t Au and 0.07% Cu from 194.63m
▪ including 17.24m at 0.45 g/t Au and 0.09% Cu from 194.63m
▪ including 8.00m at 0.67 g/t Au and 0.11% Cu from 200.00m
▪ including 2.00m at 1.28 g/t Au and 0.12% Cu from 200.00m
▪ including 34.04m at 0.39 g/t Au and 0.07%Cu from 214.96m
▪ including 7.52m at 0.67 g/t Au and 0.10% Cu from 238.48m
o 35.47m at 0.40 g/t Au and 0.06% Cu from 259.53m
▪ including 25.47m at 0.46 g/t Au and 0.06% Cu from 259.53m
▪ including 6.00m at 0.53 g/t Au and 0.06% Cu from 259.53m
o 21.45m at 0.22 g/t Au and 0.04% Cu from 346.00m
▪ including 12.00m at 0.34 g/t Au and 0.04% Cu from 346.00m
Note: Composites calculated using a 0.1 g/t Au cut off with max 4m internal dilution.
Importantly, the intercepts show a strong correlation between Au, Cu and Ag, with a negative or
low correction between Au, Te and Sb, which strongly imply a relationship to porphyry copper-
gold style mineralisation rather than higher crustal-level epithermal style gold. The geochemically
barren zone between 249.00 and 259.53m correlates with a post-mineral basaltic unit.
These compelling assay results suggest a possible vector towards the south and west of drill hole
TRNDH023 with increasing gold and copper values, magnetite, quartz vein development and
biotite-actinolite alteration, typical of a calc-potassic porphyry-proximal alteration zone (see Figure
10). This zonation is evident by the transition from distal propylitic alteration in drill hole
TRNDH017 to more porphyry -proximal calc-potassic alteration in drill holes TRNDH010 and
TRNDH023 and remains open in all directions (Figure 2).

Comparisons:
To provide some basis for the exploration relevance of the results of drill hole TRNDH023, we
provide the following comparisons from two significant alkalic Cu-Au deposits from the Macquarie
Arc. These comparisons in both grade and alteration mineralogy suggest the results from
TRNDH023 are consistent with the margins of these well documented deposits.
Magnetite-biotite-actinolite-sulphide veins are common within and/or close to the causative
intrusions at the Ridgeway deposit at Newmont Corporation’s (NYSE:NEM / TSX:NGT /
ASX:NEM) Cadia Mine (Wilson et al., 2003, Wood, 2012a and 2012b)*.

discovery hole NC498 (Wood, 2012b).

The Cadia-Ridgeway discovery sequence shows two early drill holes reporting 8m at 0.42 g/t Au
and 0.51% Cu and 102m at 0.13 g/t Au and 0.40% Cu in holes RGRC1 and NC371 respectively.
Follow-up hole NC498, drilled less than 150m under NC371, returned 145m at 4.30 g/t Au and
1.20% Cu and 84m at 7.40 g/t Au and 1.27% Cu which was widely reported as the discovery hole
(Wood, 2012b and Holliday et al., 2002) (Error! Reference source not found.).
Several comparisons can also be drawn between this intersection and the early holes drilled into
Alkane Resources Ltd.’s Boda-Kaiser deposits in New South Wales (Meates et al. 2022)*.
Early holes into the Boda-Kaiser Project reported:
o KSRC018 - 311m at 0.28 g/t Au, 0.06% Cu (See Figure 5)
o RC95DB002 - 72m at 0.26 g/t Au (no Cu reported)
o KSRC022 - 290m at 0.17 g/t Au (no Cu reported)
o KSRC020 - 233m at 0.17 g/t Au, 0.12% Cu
o KSRC016 - 176 m at 0.20 g/t Au (no Cu reported)
Follow up drillhole KSDD003 returned 502m at 0.48 g/t Au and 0.20% Cu from 211m including
108m at 1.06 g/t Au and 0.41% Cu from 408m (Figure ) (Meates et al., 2024 and other references
therein).

Duck Creek Project Drilling (Phase II):
Four Phase II mud rotary drill holes with diamond -core tails were drilled to step -out from highly
anomalous inner propylitic alteration and elevated As (>25ppm) intersected in Duck Creek drill
hole DCKDH020 for a total of 3,124m (Figure 6). Each of the four step-out holes were positioned
between 660m and 1,125m from the collar of hole DCKDH020.
Drill hole DCKDH024 was collared 800m south of DCKDH020 in a northerly direction with a dip
of -70º and to a depth of 751m. This drill hole intersected an extensive zone of inner propylitic
alteration similar to that found in hole DCKDH020 coincident with 218m of >25ppm As, elevated
magnetite content and maximum gold assay values of 2.00m at 0.12 g/t Au (Figures 7, 8 and 9).
Drill hole DCKDH022 was collared 1,125m east-northeast of hole DCKDH020 at a dip of -70º and
to a depth of 805m in a west -southwesterly direction into a large magnetic high. This hole
intersected a minor zone of inner propylitic alteration and low As values, which potentially
downgrades this specific zone to the east-north-east.
Drill hole DCKDH023 was collared 660m north of drill hole DCKDH020 in a southerly direction at
a dip of -70º and to a depth of 718m. Similarly, this hole intersected a minor zone of inner propylitic
altered basement volcanics and which potentially downgrades this specific zone to the north.
Drill hole DCKDH025 was collared 840m west of hole DCKDH020 in an easterly direction at a dip
of -70º and to a depth of 751m. This hole intersected a narrow zone of propylitic altered basement
volcanic rocks with 142m of >25ppm As from 442m.
These very broadly spaced drill holes indicate that an inner propylitic alteration system and zone
of highly elevated As anomalism is open at depth between holes DCKDH020 and DCKDH025
and will be the focus of the Company going forward. Several of the alteration footprints of other
world-class porphyry copper-gold deposits in the Macquarie Arc, such as Cadia and Northparkes,
could potentially fit within this zone (Wilson, 2003, Wood, 2012a & b and Pacey et al., 2019)*.
