Help my tire is leaking

Hello, just wanting to get peoples opinion. Do you feel this tyre is repairable or just flat our needs replacing. I am currently running a tubless set up but need to pump up my rare wheel almost every day. The bike and tires are only 10 months old. I don't think that something has lacerated the wheel as it's on both sides of the sidewall and all around the wheel and nothing on the front wheel. Cheers
