The 22-year-old left back is a product of the club's youth structures and represented the reserve side before going out on loan to Black Lions FC last season.
His time in Botswana prompted Amakhosi to hand the talented full-back a two-year contract.
But in order to secure regular game-time, Cossa will spend this season with the Patrick Phungwayo coached side, and joins fellow Kaizer Chiefs loanee Sfiso Timba at the first division club.
"Kaizer Chiefs can confirm that promising left centre-back Xolani Cossa will spend the upcoming season on loan at Gomora FC," read a Chiefs' statement.
"The 22-year-old defender, a product of the Kaizer Chiefs Youth Development Academy, is expected to get regular playing time before returning to Naturena at the end of the season, having gained valuable experience.
"Cossa joins his teammate Sfiso Timba, who also recently moved to the Gauteng-based side. The pair's presence at Gomora FC will help them gain exposure and give them opportunities to sharpen their skills at a professional level.
“The Club remains confident that both players will benefit from their time in the NFD and return to Naturena more mature, well-rounded footballers, ready to contribute to the Glamour Boys’ future success.”
