BAE Systems, former owners of the ROF factory at Euxton (now the Buckshaw Village complex) have promised £30,000 for the 8 foot high x 4 foot wide plinth.
Their generous donation means the memorial should be erected in the town in the summer of 2009.
The campaign will now major on raising money so that the names of the original 230 Chorley Pals can be added to the sandstone plinth.
