Sangare is the second Magpies young gun to link up with John Coleman’s Stanley this summer - after forward Tom Allan - in what will be the first loan move of his career so far.
It marks a homecoming of sorts for the 21-year-old, who was on the books at the Crown Ground as a teenager before switching to Tyneside in November 2016.
Sangare has still to make his senior debut for Newcastle but has played five times for his native Liberia, scoring his first international goal for the Lone Stars last September.
He made 22 appearances for the Magpies' under-23s last year before the campaign was brought to a close by the Covid-19 pandemic.
