Wendouree man Brendan Prestage has been charged with the murder of missing Ballarat mother Kobie Parfitt.
The 31-year-old was arrested on Tuesday in Kinglake near Melbourne, with the Victoria Police Critical Incident Response Team involved.
He was charged with one count of murder, and was remanded at the Melbourne Magistrates' Court on Wednesday.
He will return for a committal mention on May 5 at the Ballarat Magistrates' Court.
Ms Parfitt was last seen alive on April 28.Police found human remains in a mine shaft at Snake Gully near Ballarat on December 22 but they are yet to be identified.
Detectives spoke to a Mt Clear woman on December 23 and she was released without charge.
The investigation is ongoing.
Kobie, 43, was last seen alive at a property on Hickman Street on 28 April.
However, it was not until November that the search started to gather momentum.
Police first went public in the hunt for information on November 22, where Kobie's mother Kathy Snowball pleaded for information about her daughter.
Kobie had not had a great deal of contact with her family for some time, hence why the missing person's report took months to be filed.
"She had been estranged from the family for quite a while, but if she ever did run into family members, she would always speak to them," Ms Snowball said in November.
"I last saw her fleetingly in March this year, she was struggling."
