NexGold Initiates VTEM™ and FALCON® Gravity Airborne Geophysical Surveys at Goldboro and Announces Appointment of New Board Member

Press Release

TORONTO, May 12, 2026 — NexGold Mining Corp. (TSXV: NEXG; OTCQX: NXGCF) (“NexGold” or the “Company”) is pleased to announce that it has initiated a 2,496-line kilometre helicopter airborne Versatile Time Domain Electromagnetic Survey Plus (“VTEMTM Plus”) survey and a 2,656-line kilometre FALCON® fixed-wing airborne gravity gradiometer survey over its 32,007 hectares (~320 km2) of prospective exploration land at the Goldboro Gold Project (“Goldboro”). The surveys are expected to be completed in the second quarter of 2026 and are intended to support the development of additional exploration targets for follow-up regional exploration programs, as well as to further characterize the Goldboro Gold Deposit and its regional geological controls.

Kevin Bullock, President and CEO commented:

“We are pleased to commence both VTEMTM and FALCON® gravity surveys at the Goldboro Project. These surveys will be integrated with existing geological and geochemical data to support ongoing exploration efforts and to further characterize the Goldboro Gold Deposit. The resulting geophysical signatures are expected to assist in identifying additional exploration targets based on geological features associated with similar styles of gold mineralization.

While the Company remains focused on completing the updated Goldboro Feasibility Study, it continues to advance the broader exploration potential of the Goldboro Project with the objective of identifying additional mineralized zones beyond the current Mineral Resource. The discovery of satellite deposits could present opportunities to leverage planned mine and mill infrastructure at Goldboro and potentially support a longer-life, centralized milling operation.”

Board of Directors Appointment

NexGold is pleased to announce the appointment of David Anthony to its Board of Directors. Mr. Anthony brings more than 40 years of global experience in mine development and operations, having held senior management and executive roles overseeing the full mine life cycle, including mine and process plant design, permitting, construction, and operations. He is currently President and Chief Executive Officer and a Director of Asante Gold Corporation. Previously, Mr. Anthony served as Chief Operating Officer of Cardinal Resources Limited prior to its acquisition by Shandong Gold Mining Co., Ltd. Earlier in his career, he spent 10 years with Barrick Gold Corporation in Africa, where he ultimately served as Chief Operating Officer of African Barrick Gold.

Mr. Anthony has worked extensively in Canada, Ecuador, Brazil, Indonesia, Chile and Argentina, with experience designing, building and operating both open pit and underground mining operations.
