VANCOUVER, BC and HOUSTON, Sept. 5, 2023 /PRNewswire/ - International Battery Metals Ltd. (the "Company") is pleased to advise that on Wednesday, Aug. 30, 2023, it filed with the British Columbia Securities Commission an Annual Information Form for the financial year ending March 31, 2023 (the "AIF").
