The three offences of theft include stealing £40,901 from the club between March and September 2011.
The two other charges, involve £22,221 relating to Chorley Sporting Club, and £6,000 from Chorley FC’s Black and White draw.
Haslam also admitted to trespassing at Chorley FC’s offices between September 3 and 6, 2011, and stealing £300.
He used the same method between September 5 and 8, 2011, to steal a further £1,000.
Judge Heather Lloyd released Haslam on conditional bail until he can be sentenced. Until that time, he must live and sleep at his given address in Weldbank Lane.
She told him: “All sentencing options, including custody, are open to the judge.”
Haslam was arrested in September 2011 after the club reported concerns about alleged financial irregularities with the football club and Chorley Sporting Club, which deals with money from the social club on Victory Park.
Another man also charged with stealing from the club will face trial on January 28 at Preston Crown Court.
