Sankamap Metals Summarizes Historical Exploration Activities On Its Fauro Property

(MENAFN- Newsfile Corp) Edmonton, Alberta--(Newsfile Corp. - June 17, 2025) - Sankamap Metals Inc. (CSE: SCU) ("Sankamap" or the "Company") is pleased to provide historical exploration results from the 24,000-hectare ("ha") Fauro Property ("Fauro"), part of its Oceania Project, located in the Shortland Islands, Western Province, Solomon Islands.

The Fauro Property is strategically situated along a regional copper-gold (Cu-Au) trend that hosts world-class deposits, including both Panguna and Lihir. The Lihir deposit alone contains approximately 71 million ounces of gold1 (310 Mt containing 23 Moz Au at 2.3 g/t Proven+Probable ("P&P"), 520 Mt containing 39 Moz Au at 2.3 g/t indicated, 81 Mt containing 5 Moz Au at 1.9 g/t measured, 61 Mt containing 4.9 Moz Au at 2.3 g/t Inferred). Fauro benefits from shared tectonic and geological characteristics with both Panguna and Lihir, positioned in a highly underexplored region (See regional location map in the May 7, 2025, news release).

Historical exploration at Fauro has outlined broad zones of gold mineralization, identified through extensive surface sampling coincident with magnetic high anomalies. Rock samples have returned assays as high as 173 g/t Au and trenching yielded high grade gold results including 8 metres of 27.95 g/t Au ( See Table 1 and 2 ), all within extensive soil and rock geochemical anomalies spanning over 500 metres ( See Figures 2 and 3 ).

Reconnaissance drilling has further confirmed the presence of subsurface gold mineralization, with intercepts such as 35 metres at 2.08 g/t Au, underscoring the property's strong potential to host a significant epithermal gold system ( See Figures 1 to 3, and Table 3 ).

CEO John Florek commented

"It's not often that one has the opportunity to explore the margins of a well-defined, visually distinct caldera, particularly one marked by abundant gold-dominant mineralization and multiple high-potential targets. During our site visit in May 2025, we confirmed significant surface mineralization at one of these key target areas ( Figure 3 ).

The Fauro Property represents a high-potential epithermal gold target, validated by historical drilling, including intercepts of 11 metres grading 4.03 g/t Au⁴.

We are encouraged by the strength of past exploration results and are eager to advance the project by testing previously unassessed targets and expanding known mineralized zones; creating the potential to unlock significant value for our shareholders."

Historical Exploration Highlights

• Rock samples from the Fauro property yielded several high-grade gold assays, including a peak value of 173 g/t Au. Additional notable rock assay results included 161, 169, 139, 69.4, and 50.2 g/t Au, highlighting the property's strong mineral potential.
• Noteworthy trench sample results, included:
  • 8 metres at 27.95 g/t Au
  • 26m of 5.3 g/t Au
    20m of 4.2 g/t au
• Drilling has encountered several significant gold intercepts, including:
  • 37 metres at 1.02 g/t Au, including 4 metres at 6.75 g/t Au
  • 115 metres at 0.89 g/t Au, including 35 metres at 2.08 g/t Au and 1 metre at 44.45 g/t Au
• Extensive gold and copper anomalies have been delineated through rock and soil geochemistry.
• Magnetic anomalies show strong spatial correlation with known zones of gold mineralization.

Exploration at Fauro began in the 1980s with BHP trenching over gold-in-soil anomalies at Meriguna, yielding highlights of 30m at 1.60 g/t Au and 10m at 5.02 g/t Au. BHP drilled nine shallow holes at Meriguna and Kiovakase, followed by soil sampling and five shallow holes by Exploration Acabit in 1997.

In 2009, a prospecting license was granted to Australian Resource Management (a SolGold subsidiary), which conducted EM and IP surveys in 2010-2011, identifying six key targets: Ballyorlo, Kiovakase, Meriguna, Bataha, Ballteara, and Northern Fauro. SolGold's subsequent work included surface sampling, trenching, mapping, and drilling. Between December 2010 and 2011, nine holes totaling ~4,015m were drilled at Meriguna and Ballyorlo. Historical drilling has been shallow and limited in extent, leaving much of the property underexplored and open for further investigation.

Next Steps

Historical exploration at the Fauro Project has delineated multiple near-surface, epithermal-style gold systems with strong potential for an underlying porphyry system.

Extensive historical work: including surface sampling, trenching, soil geochemistry, and reconnaissance drilling, has outlined broad zones of copper and gold mineralization ranging from 500 m to over 1000 m on target areas Ballyorlo, Kiovakase and Meriguna ( Figures 2-3 ).

An initial site visit conducted in May 2025 served both to engage with local communities and to validate historical observations of mineralization. Rock samples were collected from the Kiovakase area confirming the presence of significant mineralization in the rocks and were submitted for assay analysis.

A phased exploration program is scheduled to begin this fall, focusing on verifying historical surficial data through systematic sampling. The results will inform the design of a potential follow-up geophysical survey aimed at identifying conductive and resistive trends typically associated with porphyry and epithermal mineral systems.

The integration of geophysical data with existing exploration results will support the planning of a targeted drilling campaign. This program will aim to confirm and expand upon historical drill results and test extensions of mineralization that remain open at depth and along strike.

These references are not intended to imply that mineralization of similar type, size, or grade is present on Sankamap's property. There has been insufficient exploration to define a mineral resource on Sankamap's property, and it is uncertain whether further exploration will result in the delineation of a mineral resource. Not all historical information including, but not limited to magnetic survey data, QAQC procedures, lab assay certificates for historical exploration and sampling is available to Sankamap metals, historical exploration was in quarterly, annual and press releases.
