Do you have a positive acting resist you have used? If so, then you can reverse it using the image reversal method. You can mix imidazole with the resist or you can use ammonia vapors to reverse it after image exposure. I will provide more details if you are interested.

I tried AZ 5214 but it doesn't seem to be compatible with gold plating. Any advice is appreciated. Thank You.
