• Economic viability not yet demonstrated - pending PEA
• Additional capital required for further drilling and studies

VANCOUVER, BC, April 15, 2025 /PRNewswire/ - Norsemont Mining Inc., (CSE: NOM) (OTCQB: NRRSF) (FWB: LXZ1) ("Norsemont" or the "Company") is pleased to announce an updated Mineral Resource Estimate ("MRE") of 2,184,000 indicated gold equivalent ounces and 557,000 inferred gold equivalent ounces for its Choquelimpie Gold-Silver-Copper Project ("Choquelimpie" or "the Project"), located in the Province of Parinacota, Region XV, Northern Chile. Norsemont holds a 100% ownership interest in the Project, through its wholly owned Chilean subsidiary, Sociedad Contractual Minera Vilacollo, ("SCMV"). The updated estimate reflects updated drilling results which continue to demonstrate the significant upside potential for the Project.

Highlights of the Updated Mineral Resource Estimate:

• Indicated Resources: 81,888,000 tonnes with grades of 0.83 AuEq, containing 1,731,000 ounces of gold at 0.66 g/t, 33,233,000 ounces of silver at 12.62 g/t and 50,867,000 pounds of copper at .04%.
• Inferred Resources: 25,267,000 tonnes with grades of 0.69 AuEq, containing 446,000 ounces of gold .55 g/t, 7,219,000 ounces of silver at 8.89 g/t and 19,104,000 pounds of copper at .04%.
• The updated MRE is based on 3,144 meters of additional drilling completed in 2021 and includes updated geological modeling and re-interpretations of several oxidation zones throughout the mineral deposit.

"This updated Mineral Resource Estimate of 2,184,000 indicated and 557,000 inferred gold equivalent ounces marks a significant milestone for Norsemont and provides a strong foundation as we advance Choquelimpie toward development," said Marc Levy, President and CEO. "The additional drilling and geological modeling increase our confidence in the resource and support our belief in Choquelimpie's significant upside potential. We look forward to progressing toward a preliminary economic assessment and further exploration to grow this resource base."

Notes:
1)	Scott Wilson, CPG, President of RDA is responsible for this mineral resource estimate and is an "independent Qualified Person" as such term is defined by NI 43-101.
2)	The Mineral Resources, effective date March 31, 2025, are reported at an in-situ cut-off grade of 0.17 g/t Au for Oxide, 0.18 g/t Au for Mixed which is included in the tabulation of oxide in the above table and 0.28 g/t Au for Sulfide mineralization. The cutoff grades have been derived US$2,500/oz, a silver price of US$28.0/oz and a copper price of US$4.00/lb. and suitable benchmarked technical and economic parameters for open pit mining (mining = US$3.50, processing = US$11.0 for crushing and leaching of oxides and US$20 for milling of sulfides).
3)	Metal recoveries are assumed to be Oxide Crush/Leach 80%Au, 45%Ag, 0%Cu; Mixed Crush/Leach 75% Au, 25%Ag, 0%Cu; Sulfide Milling 90%Au, 80%Ag and 75% Cu.
4)	Metal Equivalent ounces are calculated using the formula: Au Eq Oz = AU Oz + (OzAg*AgPrice/AUPrice)+(CuGrade*CuPrice/AuPrice)
5)	Mineral resources are not mineral reserves and do not have demonstrated economic viability. Gold, silver, lead and copper assays were capped where appropriate. Given historical production, it is the company's opinion that all the elements included in the metal equivalents calculation have a reasonable potential to be recovered and sold.
6)	All figures rounded to reflect the relative accuracy of the estimates.

Next Steps

Norsemont plans to conduct additional drilling into oxide and sulfide zones to expand and upgrade the current resource. Metallurgical testing and economic studies are also planned as part of the Company's broader efforts to advance the Project toward a Preliminary Economic Assessment.

Cautionary Statement on Mineral Resources

Mineral resources are not mineral reserves and do not have demonstrated economic viability. The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, socio-political, marketing, or other relevant issues. In particular, the quantity and grade of reported inferred mineral resources are uncertain in nature and there is insufficient exploration to define these inferred mineral resources as an indicated or measured mineral resource in all cases. It is uncertain in all cases whether further exploration will result in upgrading the inferred mineral resources to an indicated or measured mineral resource category.
