WIMMERA residents will have a chance to dig for diamonds in Horsham.
Two champagne diamonds, along with hundreds of other prizes, will be up for grabs as people search through 80 tonnes of sand.
The twilight diamond dig on the Horsham Showground river front is a fundraiser for the 100 Chicks Chase 100 Clicks initiative.
It will see 100 individuals, or teams of up to four women, attempt to raise $100,000 as they walk 100 kilometres from Halls Gap to Horsham.
The money will go towards Wimmera projects.
Project manager Andrea Cross said the diamond dig was unique to the Wimmera.
"It was a fundraiser that we adopted from an event in Kununurra to bring to Horsham," she said.
"It's generated a real buzz on Facebook and we think it's going to be great.''
Mrs Cross said organisers had been blown away by the support of businesses.
"The prizes just keep rolling in," she said.
"We're going to write numbers corresponding with prizes on ping pong balls and throw them into the sand as it's being unloaded."
Along with diamonds, prizes will include an accommodation package, an iPad mini, gift vouchers and sports cameras.
Entry to the event is $15 for adults $10 for entrants in the 100 Chicks Chase 100 Clicks challenge and $5 for children 15 and under.
Mrs Cross said tickets should be pre-purchased and were available from the Commonwealth Bank office in Hamilton Street and Roberts Avenue Hair Design.
The 100 Chicks Chase 100 Clicks walk was initially planned for March, but has been postponed until the Anzac Day long weekend following the region's bushfires.
