Norsemont Commences Drill Program at Choquelimpie Project

Highlights

• The first diamond drill rig is currently on site, with the second rig expected to arrive next week.

• The Phase 3 program includes up to 20 diamond drill holes, totaling approximately 5,000 meters

• Drilling will test extensions of higher-grade hydrothermal breccia bodies at depth, below the current mineral resource envelope.

Management Comments

Norsemont CEO Marc Levy commented:

"We are very excited to launch Phase 3 drilling at Choquelimpie, where our recent work has highlighted significant potential for higher-grade gold zones at depth beneath the current resource and along strike. This high impact program will be testing higher grade mineralization at depth in several zones such as Choque, Vizcacha and Suri. The program marks an important step forward as we continue to define the scale and continuity of mineralization across the project. With two rigs on site, we expect steady progress and consistent news flow over the coming months."

The Phase 3 Drill Program

The Phase 3 drill campaign at Choquelimpie is designed to evaluate down-dip extensions of high-grade gold mineralization hosted within hydrothermal breccia zones. The program will comprise up to 20 holes averaging 250 meters in length.

Norsemont, through its wholly owned Chilean subsidiary SCM Vilacollo, has engaged DV Drilling Ltd. of Coquimbo, Chile, to conduct the program. DV Drilling will mobilize two (2) Longyear LF230 track-mounted diamond drill rigs, which will operate on a 24-hour schedule throughout the campaign.

Historical production at Choquelimpie during the period of 1988 to 1996 focused primarily on oxidized near-surface mineralization between 20 and 100 m depth, depending in the type of rock, alteration and mineralogy. Consequently, much of the exploration at the Project focused on this near surface oxide resource without testing the deeper, potentially larger, sulphide resource. The Phase 3 drill program aims to systematically assess this deeper resource potential by targeting the geometry of the higher-grade breccia bodies.
