Brock Lewthwaite’s big Goldfields campaign is all but over as a spell looms for Monty Zoomer; but whatever the future holds for the consistent gelding, the Forrestdale trainer said it had been a memorable ride at Kalgoorlie-Boulder Racing Club.

The five-year-old on Sunday extended an imposing record at Kalgoorlie Racecourse with victory in the $24,000 Black Diamond Drilling Handicap, his sixth since debuting at KBRC last October, and his fifth this season.

It is backed this campaign by two seconds and three thirds, that extended his lead for the KBRC’s horse of the year to eight points over Spangledstar.

“I initially brought him up (to the Goldfields) late last year, just to test the waters, and he got the job done,” Lewthwaite said.

“It was probably only my third run with him and from there we knew we had a good Kalgoorlie horse for this season but, boy, he keeps raising the bar.”

Lewthwaite explained how spelling Monty Zoomer relatively soon after a late-2025 debut at KBRC had brought resounding results.

“We tried him over ground in Perth, and he ran second by a nose at his last start at Narrogin which was over 2000m,” he said.

“Then we tipped him out, in-form — to have him fresh in Kalgoorlie for the sprinting.

“And it’s working a treat.”

But he said that all good things must come to an end.

“The whole team has been consistent but because he makes his own luck, bad luck hasn’t got in the way,” Lewthwaite said.

“It shows the true form of the stable because he hasn’t missed a top-three (placing).

“It’s hard to pinpoint because he’d been racing in Carnarvon without a lot of success and to then come to me and go so well, again I think the best thing I did was to spell him while he was in form.

“We’d figured him out last preparation, and that gave us an easy horse to work with this time in.

“We’re a good fit — me and him.

“But my business in Kalgoorlie was definitely through the first half of the season, and I won’t be as active as I have been.

“He’s going so well and it’s hard to stop, but I’m aware that he deserves a rest soon.”

Lewthwaite said he was planning “one more roll of the dice” with four runners at the KBRC’s next meeting on July 26.

He was among three trainers last Sunday with two winners, alongside Peter Fernie and Ashley Maley, after Deeply Rooted ($13) was also successful.

Natika Riordan was aboard for both winners, and Lucy Fiore also had a riding double.
