Key Adjustments for 

GCMRC FY24 Budget 

 Adjustments related to:

 Cost-of-living, grade/step increases, position fills 

 Logistics increase of 10% due to impacts of 

inflation, etc.

 Overhead rate decrease...current estimate for FY24 

is 18% compared to the planned 28%

Additional Funds Outlook for 

GCMRC FY24 Budget 

 Unspent funds at close of FY23 appears likely

 Current estimate is roughly $750,000 to $1M

 Stems mainly from overhead difference and funds 

leftover from prior fiscal years

 Use of latter is dependent on Reclamation approval
