It's lifted John Pemberton's men up to 20th in the table.
Chesterfield have climbed out of the National League relegation zone after claiming a vital three points at Chorley on Saturday-winning 2-1 in Lancashire.
It's the first time the Spireites have been out of the bottom four for three months.
Tom Denton scored his third goal in four games on the forty minute mark, as he headed in from close range to give the visitors the lead at half time.
Things got worse for bottom-of-the-league Chorley on sixty-four minutes when Jordan Cropper scored his first senior goal.
The on-loan Burnley full back managed to score from a tight angle after he got onto the end of Nathan Tyson's cross.
However, Chorley ensured it would be a tense finish at Victory Park when they halved the deficit twelve minutes later.
Connor Hall finished a quickly taken free-kick, but the hosts, who're now seventeen points from safety with eight games remaining, were unable to get back on level terms.
Speaking afterwards, 19 year old Cropper expressed his delight at getting the winner;
"I knew Nathan Tyson had the beating of his man, so I called for him to get it across the box.
"It turned out to be a great ball and luckily I got on the end of it.
"It wasn't our best performance, but we're buzzing to be out of the bottom four."
Chesterfield return to National League action next Saturday at Dover Athletic.
