SIENNA HIRES DRILLER FOR FIRST PHASE OF DRILLING ON THE "ELKO LITHIUM PROJECT" IN ELKO COUNTY, NEVADA BORDERING SURGE BATTERY METALS

Sienna Resources Inc. has contracted Alloy Drilling LLC of Elko, Nev., for the first phase of drilling expected to commence in October. Recently, Sienna received approval from the BLM (Bureau of Land Management) to drill up to five initial locations on its recently acquired Elko lithium project in Elko county, Nevada. This project consists of approximately 1,200 contiguous acres directly bordering Surge Battery Metals' Nevada North lithium project in Elko county, Nevada. According to the news dated Sept. 12, 2023, from Surge: "The first certified analytical results for the 2023 summer drilling program at Surge Battery Metals Inc.'s Nevada North lithium project (NNLP) have returned multiple zones of high values ranging from 1,000 parts per million to 8,070 ppm lithium, the highest grades for exploration to date on the Nevada North lithium project. Sienna management cautions that past results or discoveries on properties in proximity to sienna may not necessarily be indicative of the presence of mineralization on the company's properties."

Jason Gigliotti, president of Sienna, states: "We are very pleased to be able to put this drill program together. Alloy has a proven track record of drilling success in the area and we are looking forward to working with them on this first phase of drilling. This drill program could be a game changer for Sienna when you consider the market reaction to our neighbour, Surge Battery Metals, whose shares have risen from a low of 6.5 cents to a recent high of $1.55 based on their drill results right beside Sienna's property. Not only do we have this new lithium project, but Sienna is one of the largest landholders in Clayton Valley, Nevada, through its other property interests. Sienna has more than enough cash on hand for the anticipated current exploration plans and we expect to be very active on multiple fronts for the remainder of 2023. Management is extremely optimistic about the future and looks forward to what will happen with this planned drill program. The next few weeks and months will be a very exciting time for Sienna management and shareholders."

Recently, the Bureau of Land Management has also given Sienna approval for up to four additional holes to be completed on the 100-per-cent-owned Blue Clay lithium project in Clayton Valley, Nevada. On March 25, 2022, Sienna revealed a new lithium discovery on the Blue Clay lithium project. Lithium values as high as 1,230 ppm Li were encountered. The Blue Clay lithium project consists of 150 contiguous claims totalling approximately 2,950 acres prospective for lithium right in the heart of the Clayton Valley in Nevada, which is currently home to the only producing lithium region in North America.

The company has entered into a media services agreement with Life Water Media of Sugar Land, Tex., dated Oct. 13, 2023, whereby the services to be provided by Life Water Media will include digital media, marketing strategies, advertising and awareness campaigns for a fee of $100,000 (U.S.) for a term of three months upon TSX Venture Exchange approval. The fee shall be paid upfront with cash on hand. The agreement may be renewed or extended by the company and Life Water Media at the end of the initial term.

Life Water Media and Sienna are not related parties and operate at arm's length. Neither Life Water Media nor its principals have any interest in the company's securities, directly or indirectly, or any right or intent to acquire such an interest. Life Water's contact is Enrique David Pena. The company will provide Life Water with publicly available source information for its disclosure and the company will be involved in reviewing the materials for accuracy prior to its dissemination.
