Detectives have been conducting investigations into the alleged supply of drugs in the area over the last 11 months and it's led to the arrest of a woman in Forbes.

Rural crime investigators and criminal investigators from Central West Police District established Strike Force Goovigen last year in December to investigate drug, firearms and property offences in Parkes, Forbes and Condobolin.

Strike Force Goovigen detectives executed a search warrant at a home in Forbes where a 29-year-old woman was arrested, NSW Police said in a statement issued to media on Wednesday afternoon.

During the search of the woman and the house, officers allegedly found and seized replica firearms, ammunition, a slingshot and methylamphetamine.

She was taken to Parkes Police Station where she was charged with recklessly deal with proceeds of crime and six counts of supply prohibited drug.

She was refused bail to appear before Bail Division Court 4 today, 2 October.

Investigations under Strike Force Goovigen continue.
