Salgaocar, who looked the better of the two sides in the first half, took the lead in the 40th minute through Darryl Duffy.
But Dempo fought back, especially in the latter part of the second half, with Jeje Lalpekhlua scoring an equaliser at the 81st minute.
While Salgaocar now have seven points from two wins and a draw, Dempo, who drew their third match, have three points from four outings.
Both the teams played an attacking game.
With more ball possession, Salgaocar mounted pressure on the rival goal from the flanks with Francis Fernandes providing some nice crosses for strikers Gnakpa and Duffy and the latter, after missing a couple of close chances, put Salgaocar ahead in the 40 minute.
Defender Nicolau Colaco, who overlapped constantly on the right, cut past a rival defender and released the ball to Duffy who placed it into the net past keeper Subhasish Roychowdhury to have Salgaocar leading 1-0 at half time.
They too had their share of exchanges and chances but once Roberto Silva's shot missed the target narrowly and later Clifford Miranda's attempt at goal was punched over by keeper Karanjit Singh.
