A racehorse has tested positive to methamphetamine after placing second at a race in regional Queensland.

Five-year-old mare Party Till Dawn is the second horse in just over a year to test positive for the drug, according to the Guardian .

Trainer Ben Currie is expected to face the Queensland Racing Integrity Commission (QRIC) next week for an inquiry.

He told the ABC earlier this week he had a good case to fight the charges, but did not want to comment further while the matter was under investigation.

Last week, Mr Currie was fined $6000 by the QRIC after his horse Tints tested positive for the banned substance boldenone.

Boldenone is a synthetic steroid drug that can enhance appetite and increase muscle mass in horses.

The trainer has said he would appeal the charge.

"I think we had some good points that we brought to the table," he told ABC.
