I doubt that would exist. The most detailed file on BLM's Colorado site is 1/4 of 1/4. Their Geocommunicator site for active and closed claims states 'Keep in Mind that these are only the BLM LR2000 claims. To find out their actual boundaries you must go to the appropriate County Recorders office.'
BTW - SW of SW of NW of SE is 1/4*1/4*1/4*1/4 = 256 equal sub-sections
1/4*1/4*1/4 = 64
1/4*1/4 = 16
Thinking back to my Colorado PLSS and Colorado PLSS QQS overlay map sets; the PLSS QQS one appears to include outlines of mining claims. Current file (in shape format) on the BLM website was created 2020 Sept 11.

Third screen down under Administrative Units - click on + for cadastral.
Fifth bullet down - PLSS Second Division (Aliquots)
I would expect the other BLM state office websites to have similar data files. No info on the 'claim holes', just the 'name' and acreage for the 1/4*1/4's
