Jindalee Lithium Limited (Jindalee, or the Company; ASX: JLL, OTCQX: JNDAF) is pleased to advise that its wholly owned US subsidiary HiTech Minerals Inc. (HiTech) has signed a Letter of Understanding (LOU) covering the McDermitt Lithium Project (McDermitt, or Project) with the Oregon Building Trades Unions (OBTU). HiTech holds the McDermitt Project located in southeast Oregon, which is one of the largest lithium deposits in the US and of global significance1. Discussion The McDermitt Pre-Feasibility Study (PFS) completed in November 2024 estimated that development of the Project could generate approximately 1,000 direct construction jobs during the build phase and approximately 600 direct permanent operational jobs over an expected operational life exceeding 60 years1. Access to skilled labour will be critical to the success of the Project. The OBTU is a statewide umbrella organization comprised of 31 affiliate member Trade Unions representing tens of thousands of skilled trades workers across Oregon. The OBTU is in support of the Project and has agreed to work in good faith with HiTech towards negotiation of a mutually acceptable binding Project Labour Agreement (PLA) requiring all project construction work within the jurisdiction of the OBTU to be performed by union labour. The LOU envisages that HiTech will require, after final approval of the Project and within a reasonable time period prior to the start of construction, that general contractors enter into a mutually acceptable PLA that meets the approval process of North America’s Building Trades Unions (NABTU), and is within the current jurisdiction of the OBTU and their district council and local unions. Jindalee’s Managing Director and CEO Ian Rodger commented: “We are very pleased to announce the signing of the LOU with the OBTU. McDermitt has the potential to be one of the largest projects developed in rural Oregon and we are delighted to be partnering with the OBTU to help develop the skilled workforce required to responsibly advance the Project for the benefit of all stakeholders.” JNDAF 5 February 2026 Key Agreement signed with Oregon Building Trades Unions (OBTU) • Letter of Understanding (LOU) signed with OBTU covering Jindalee’s McDermitt Project • Highly skilled workers will be required for both construction and operation of the Project • The OBTU represents thousands of trades workers across Oregon and has committed to support the Project LOU Signed with OBTU – February 2026 Figure 1 – Jindalee management and senior OBTU officials at signing ceremony in Portland, Oregon Figure 2 – Jindalee management and senior OBTU officials at the Oregon State Capitol in Salem, Oregon LOU Signed with OBTU – February 2026 Authorised for release by the Jindalee Board of Directors.
