Toowoomba racehorse trainer Ben Currie will face the Queensland Racing Integrity Commission (QRIC) next week after one of his horses returned a positive sample for methamphetamine.

QRIC commissioner Ross Barnett said the sample was taken from the horse Party Till Dawn at a race meeting in Toowoomba in June.

Since being under Currie's management, the five-year-old mare had raced twice, placing second in both the minor class two races at the track on June 11 and 25.

Owners transferred the horse to Currie's stables at the end of May from the care of Gold Coast trainer Stephen Jones.

Across its career, the horse had posted three wins and five seconds from 22 starts, earning a total of $55,215.

Currie, 25, told the ABC he had a good case to fight the charges, but he did not want to comment further while the matter was under investigation.

QRIC said the only other instance of a Queensland horse testing positive for methamphetamine was in Mackay in October 2015.

Trainer Cassandra Marsh was fined $5,000 after providing sufficient evidence that her horse, Island Tang, had been in contact with a habitual user of methamphetamine.

Currie fined this week in separate matter

It is the second serious charge for Currie in his five-year career as a trainer.

On Wednesday, he was found guilty and fined $6,000 by the QRIC after his horse Tints tested positive for the banned substance boldenone in Rockhampton on April 8.

Boldenone is defined as a synthetic steroid hormone resembling testosterone in its ability to promote the growth of muscle.

Currie said he would appeal that ruling.

"I think we had some good points that we brought to the table, and I feel like we've got a good chance further down the track to win the case on appeal and clear the charge," he said.
