Renee MacRae, 36, from Inverness, and her three-year-old son Andrew disappeared on 12 November 1976.
An estimated 13 million litres of water has been pumped from Leanach quarry at Culloden, near Inverness.
Silt and debris at the bottom will now be removed and taken to another location for forensic tests.
Detectives announced last month that they intended to drain the quarry in an effort to solve the mystery.
On the evening of her disappearance, Mrs MacRae, who was estranged from her husband Gordon, had set off for Perth with the youngest of her two sons, Andrew, to meet her lover Bill McDowell, Mr MacRae’s married accountant.
He told police they never met.
Mrs MacRae’s burnt-out BMW car was discovered on the night she disappeared in a lay-by on the A9 south of Inverness.
Det Insp Brian Geddes, of Police Scotland, said an “incredible” and “tireless” operation to drain the quarry meant detectives could start the “detailed searching phase” of the operation.
He said: “Pumping the water clear was a huge challenge, but we have made fantastic progress in a very short time.
“Silt and debris from the bottom of the quarry are now being removed by lorry to undergo forensic tests at another location.
“The whole team remains extremely confident that vital evidence we believe was hidden in Leanach will be recovered in the coming weeks.
“I want to reassure the family and friends of Renee and Andrew that we will not be leaving here until every last inch is searched.”
