Two games to go and the Spireites' destiny is in their own hands: beat Bury on True Blue Day at the Proact and the side will be playing in Sky Bet League 1 again in 2016/17.
Four points ahead of the drop zone results elsewhere could also see the Spireites safe, but Danny Wilson has said his squad want survival confirmed quickly and by their own hand.
For True Blue Day tickets in all home areas of the ground have been slashed to just £10 for adults and £5 for kids, with over 1,500 fans already taking advantage of the fantastic offer.
Spireites supporters can purchase tickets at these reduced rates from 9am right up to kick-off, or they can purchase online here
and collect their tickets before the game.
Danny Wilson's major concern comes over the fitness of striker Lee Novak, who was substituted in the first half of last weekend's Swindon match with a knee injury, his manager saying pre-match that his availability would be left until Saturday to give Novak the best chance of featuring.
Elsewhere, Dion Donohue has returned to training and could be considered for selection, while defender Charlie Raglan is a certain absentee as he serves his one-match ban for the two yellow cards he received at the County Ground.
For the opposition, former Spireites striker Leon Clarke will miss the rest of the season after picking up an ankle injury during last Tuesday’s defeat to Scunthorpe United, while Joe Riley is touch-and-go for the match.
Shakers skipper Nathan Cameron and 'keeper Rob Lainton remain absent for Bury, midfielder Jacob Mellis is fit again after recovering from his ankle injury and may feature at the Proact, however Andrew Tutte won’t be fit enough for Saturday as he’s been suffering with a hamstring problem.
After weeks of result cross-checking and points projections there is now little uncertainty in what Saturday's hosts need to do to ensure their League One survival. Regardless of results around the country the Spireites will be safe if they can pick up their sixth win of a poor home campaign.
They have had chances in recent weeks to have already secured their third-tier future, but just one point from their last three matches has increased the edginess back at the Proact, culminating in what Sam Hird called a "rubbish" performance as Swindon last time out.
Bury are seven points north of the Spireites and long since assured of a second straight season in the division, coming to North Derbyshire with just pride to play for in 15th spot.
From the Dugout
Ahead of the game, manager Wilson said he expects a display full of attacking verve from his side in their attempt to secure their future.
"We've approached every game that we've been involved in looking to win," he explained. "But for this particular game it needs to be a rip-roarer. It needs to be high-tempo game where we bombard them in key areas of the pitch to try and score.
"Hopefully, the fans pressing and encouraging us to do that will be enough at the weekend."
While it may on the face of things be an end of season wind-down match for Bury, Wilson said that he's sure the Shakers will give his Spireites side anything but an easy ride.
"The pressure's certainly off them, but I don't think the manager will let them take their foot off the gas, they'll come with the same vigour that they would if they were fighting for their lives as well.
"A good end of the season always bodes well for the start of the next season, and that's something that the manager will be drilling into his players, I'm sure of that.
"There will be players unsure of their futures, who want to put in good performances to ensure they're still at Bury next season.
"We don't expect it to be any different of a contest than if it had been a middle of the season game."
