Rover Metals Announces Results of Expanded Phase 1 Surface Exploration Program at Its LGL Lithium Project, Nevada, USA

VANCOUVER, BC / ACCESSWIRE / September 7, 2023 / Rover Metals Corp. (TSXV:ROVR)(OTCQB:ROVMF)(FSE:4XO) ("Rover" or the "Company") is pleased to announce that further to its release of August 1, 2023, management of the Company, including Mr. James Ingraffia, have completed a successful field visit and surface sampling program at the Let's Go Lithium ("LGL") project, NV, USA.

Summer 2023 Work Program
Management, including Mr. Ingraffia, spent a week in the field this summer at the LGL program. The purpose of the field visit was to orient Mr. Ingraffia with the project as well as confirm previously reported high-grade lithium surface samples at the project, with the goal of starting work on a geological map of the clay body at LGL. Mr. Ingraffia will work with Rover's CEO, in the coming weeks and months, on a Plan of Operations For Exploration and any necessary environmental assessment that may be required under the U.S. National Environmental Policy Act ("NEPA").

James Ingraffia
James is a senior lithium geologist specializing in Nevada. Mr. Ingraffia is the founder of Lithium Arrow LLC. He has seven years of experience in lithium economic geology, and is a highly trained specialist in lithium claystone and experienced in lithium brines and pegmatites. He got his start with the United States Geological Survey in lithium brine and claystone geochemistry, in partnership with Pure Energy Minerals before its purchase by Schlumberger. He then characterized the Thacker Pass lithium claystone deposit, from the atomic to kilometer scale, and published the results in partnership with Lithium Americas Corporation and the Nevada Bureau of Mines and Geology. He holds a Master's Degree of Geology, with training in Business Administration, from the University of Nevada Reno and a Bachelor's of Geology from California State University Northridge. Mr. Ingraffia is based in Reno, NV.

Surface Sampling Results
The results of Mr. Ingraffia's surface sampling work is provided in the below table. Lithium grades have been analyzed using a SkiAps 903 Handheld Laser Induced Breakdown Spectroscopy ("HH LIBS"):

Sample ID	Method	Grade (ppm Li)
348222 averaged	HH LIBS	850.35
348421	HH LIBS	680.1
348420 averaged	HH LIBS	1,032.75
348419	HH LIBS	371.9
348418	HH LIBS	606.9
348417	HH LIBS	436.6
348416	HH LIBS	631.4
348415	HH LIBS	253.4
348414	HH LIBS	417.3

A SkiAps LIBs 903 analyzer was used to assay these samples. The QA/QC protocols for the LIBs are as follows: (a) it was calibrated for Claystones; (b) it was tested on a known Claystones lithium sample prior to fieldwork; and (c) the field samples were shot in a controlled environment, inside, with proper cleansing of the lens, and sample separation. The highest grades were shot several times to try to eliminate any nugget affect; (d) fine ground particulates were not tested, so no pucking was necessary.
