- Strong cash position of C$13.1 million to fund exploration program
- Strategic location near historic high-grade gold sample of 18.7 g/t
- Planned expansion with 10,000 metres of additional drilling across two projects
- Results are early-stage and require further validation through diamond drilling
- Base-of-till (BOT) sample results still pending
- Gold values are relatively low grade compared to historic samples
Key Highlights
- Bunker Hill winter drilling program concluded: Drilled combined total of 5,067 metres of diamond and reverse circulation ("RC") drilling completed.
- RC drill program completed 147 holes: Shallow drill holes drilled at Bunker Hill to collect base-of-till ("BOT") and bottom-of-hole ("BOH") samples to detect gold in basement. BOT results are pending.
- Bedrock gold discovered on a major structure: RC drill hole CRC0284 reported an average of 417 ppb gold over six metres with a peak gold value of 893 ppb gold, silver value of 3.7 g/t and lead of
0.92% on the Branch Fault, a major structure splaying off the Cape Ray Shear Zone ("CRSZ"), and five kilometres along strike from a historic 18 g/t gold outcropping sample. - Proven BOH drilling methodology: Widely used in Australia and Scandinavia, this approach has been instrumental in the discovery of several major gold deposits, with early-stage results typically ranging from 10 ppb to 2,000 ppb gold (see Table 1).
- Multiple bedrock samples received: Three additional RC holes returned bedrock anomalism of 219 ppb (CRC0216), 160 ppb (CRC0273) and 129 ppb (CRC0215) gold.
- Diamond drilling resumes in June: Planning 5,000 metres of drilling at the Cape Ray Project beginning in June 2025 and an additional 5,000 metres planned for Bunker Hill beginning in mid-year.
Edmonton, Alberta--(Newsfile Corp. - May 6, 2025) - AuMEGA Metals Ltd (ASX: AAM) (TSXV: AUM) (OTCQB: AUMMF) ("AuMEGA" or "the Company") is pleased to report assay results from the BOH phase of its winter RC and diamond drill program at the Bunker Hill Project, located along the CRSZ in Newfoundland and Labrador, Canada ("Newfoundland").
A total of 147 RC holes were drilled across a key area between the Nitty Gritty and Bunker Hill West targets (refer Figure 1). Assays for BOT samples and diamond drilling from the winter campaign remain pending.
AuMEGA Metal's Managing Director and CEO, Sam Pazuki commented
"We are highly encouraged by the results from our winter RC program. While bottom-of-hole and basal-till drilling are rarely applied in Canada, they are proven exploration methods in major mining jurisdictions like Australia and Finland, where they've led to significant gold discoveries beneath cover.
Our standout result came from hole CRC284, drilled directly into the Branch Fault, a major structure off the Cape Ray-Valentine Lake Shear Zone. This shallow hole intersected several metres of finely disseminated galena, a key pathfinder for gold at both Cape Ray and Bunker Hill West. Notably, this structure is also the site of a historic 18.7 g/t gold outcrop, reinforcing its prospectivity. The assays confirm that gold is associated with the galena in CRC284, making it the strongest BOH result the Company has drilled to date.
Following visual inspection, we mobilised a diamond rig and completed two follow-up holes, including one that intersected the Branch Fault at depth. We are awaiting assay results on these two holes as well as the other diamond drill holes and base-of-till samples.
Looking ahead, we plan to resume fieldwork in mid-May at Cape Ray, followed by a 5,000-metre diamond drill program starting in June. This campaign will include step-out drilling from existing resources and testing new targets several kilometres from known deposits. In mid-July, we'll return to Bunker Hill for Heli-supported diamond drilling at Bunker Hill West, along with follow-up work at Nitty Gritty and other high-priority targets."

RC BOH and BOT Exploration Methodology
Reconnaissance-style BOH and BOT RC drilling is a highly effective exploration technique for rapidly screening large, overburden-covered areas. Shallow, grid-pattern drilling targets till and top-of-bedrock samples to pinpoint gold and pathfinder anomalies. While rarely used in Canada, this method mirrors successful Australian rotary air blast ("RAB") and Aircore BOH programs, as well as Scandinavian BOT campaigns - techniques that have driven major discoveries globally (see Table 1).
Table 1: Examples of discoveries made through BOH and BOT programs
| PROJECT | OWNER | TYPE OF BOH / BOT DRILLING | INITIAL RESULTS | DEPOSIT SIZE |
| Ikkari | Rupert Resources | RC Drilling | 0.2 ppm gold | + 4 Moz gold |
| Gruyere | Gold Road / Gold Fields | RAB & Aircore Drilling | 10 to 100 ppb gold | 8 - 10 Moz gold |
| Hemi | De Grey Mining | Aircore Drilling | 2000 ppb gold | 10 Moz gold |
| Tropicana | Anglo Ashanti | Aircore / RC Drilling | 200 to 2000 ppb gold | 8 - 10 Moz gold |
| Invincible | Gold Fields | Aircore / RC Drilling | 10 ppb gold | >5 Moz gold |
Bunker Hill Winter Drill Program Overview
During the 2025 winter program at Bunker Hill, AuMEGA completed 147 RC holes totaling 1,390 metres. The program focused on drilling through glacial cover to sample both the lowermost till and uppermost bedrock. Drillholes were spaced 50 metres apart along 1,200-metre-spaced lines, with an average hole depth of 10 metres and the deepest hole reaching 32 metres. The average till thickness is approximately three metres.
Drilling targeted the central corridor of the Bunker Hill Project, between the Nitty Gritty and Bunker Hill West targets (refer Figure 2), an area underlain by several high-potential structures identified in geophysics and near historic base metal anomalies in overburden samples1.

RC Drilling Returns Strong Gold and Base Metal Anomalies at Bunker Hill
The RC BOH program at Bunker Hill returned multiple anomalous gold intervals, considered significant for this early-stage style of exploration. All BOH assay results have been received, with results from the BOT samples pending.
A standout result came from hole CRC0284, which returned a weighted average of 417 ppb gold over six metres from two metres downhole, with mineralisation starting at the overburden-bedrock interface (refer Figure 3). The drill hole was consistently mineralised with fine disseminated galena, considered a key pathfinder for gold on the CRSZ.
Notable intervals from CRC0284 include:
2 to 3 metres: 789 ppb Au, 0.72 g/t Ag,
0.27% Pb,0.23% Zn3 to 4 metres: 246 ppb Au, 1.23 g/t Ag,
0.18% Pb4 to 5 metres: 374 ppb Au, 2.43 g/t Ag,
0.51% Pb,0.49% Zn5 to 6 metres: 49 ppb Au, 1.21 g/t Ag,
0.46% Pb,0.41% Zn6 to7 metres: 191 ppb Au, 0.84 g/t Ag,
0.30% Pb,0.28% Zn7 to 8 metres: 853 ppb Au, 3.71 g/t Ag,
0.93% Pb,0.31% Zn
Comparing these results to the initial results illustrated in Table 1, demonstrates the significance of the BOH results from the Company's winter BOH RC drill program.

CRC0284 was drilled into the Branch Fault and is located just five kilometres from a historic outcrop sample grading 18.7 g/t gold, also associated with galena. Visual inspection of RC chips confirmed quartz veining and base metal sulphides hosted in felsic granite2, consistent with previous discoveries at Bunker Hill West (see Figure 4).
Following these results, the Company mobilized a diamond drill rig to test the structure at depth, completing two follow-up diamond holes below CRC284 (see Figure 4). Assay results from these diamond holes are pending.

Other Anomalous Samples
In addition to CRC0284, three other RC holes returned significant gold anomalism. Notably, CRC0215, CRC0216, and CRC0273 intersected 219ppb, 129ppb, and 160ppb gold respectively in bedrock along a splay structure off the CRSZ, located between a gabbroic unit to the north and the Billard's sedimentary formation to the south (refer Figure 5). This setting is a strong rheological structure that is conducive for hosting mineralised systems. An example of this is on the CRSZ at the Company's high-grade Isle aux Morts deposit where it is hosted in similar sediments on the contact with a gabbro3.

Diamond Drilling Update
AuMEGA completed 14 diamond drill holes totalling 3,670 metres as part of its winter program (refer Figure 2). Five drill holes targeted the Nitty Gritty area, while other holes were drilled along the corridor between Nitty Gritty and Bunker Hill West, including follow-ups to encouraging RC rock chip visuals - most notably, CRC0284, which returned a significant BOH gold anomaly.
To date, samples for five diamond drill holes have been received by the laboratory for assay, including CRD397, which tested the Branch Fault directly beneath CRC0284. Remaining diamond drill holes are being logged and processed and samples submittal to the laboratory is ongoing.
Assay results for all submitted diamond drill holes are pending.
Next Steps
While AuMEGA is finalising delivery of remaining core samples and awaiting final results, exploration field work is set to resume at the Cape Ray Project in mid-May 2025. The Company will also be completing an airborne electromagnetic survey over the Cape Ray Project from the Isle Aux Morts zone to Cape Ray West. In June, the Company expects to begin a 5,000-metre diamond drill program at Cape Ray.
The Company will continue to evaluate results from the winter drill program to refine targets for the next phase of exploration at Bunker Hill, which is expected to resume in mid-July. Initial drilling focus will be on Bunker Hill West, with additional drilling and ground-based exploration planned across the broader project area.
