The Magpies scored the only goal of the game in the 35th minute when Enoch Showunmi tapped-in after good work by Andre Boucard and Jamal Campbell-Ryce. However, the home side had Gary Liddle to thank after some heroic defending saw him clear Matt Smith's goal-bound header off the line on 57 minutes.
Curle said: "I think the football in the first half was exceptional. We got the ball in the box quickly and gave them a lot of problems. That performance could and maybe should have seen us score two or three goals and I don't think they could have had any complaints.
"Second half was different and we didn't play the football we had played in the first half but we stood up to the test well. There was a bit of nervousness, especially because of our recent home record, but the players showed a lot of character."
Curle was happy to see summer signing Showunmi get a goal on a rare outing in what has been a frustrating season so far for both the player and the club.
He said: "It's a bit of payback time. Enoch has now got to come to the fore and follow that performance up. He can be a goal threat and now he is starting to believe that he is going to score goals for us and sometimes that is all it is - belief. It will do him the world of good scoring but even better would be two in two."
Oldham manager Paul Dickov was left to reflect on another defeat for his struggling side and was disappointed at his player's ineffectual display, particularly in the first half.
Dickov, whose side host Liverpool on Sunday, said: "First half we were sloppy and we didn't get anywhere near them that often. I said to them at half-time if any of them thought they would be playing a full game they would have to improve and if I could have made more changes I would have.
"After they had a bit of a rollicking at half-time they came out better second-half and gave it more of a go and could have got something.
"We have all got to learn that you can't just turn up on a match day and just expect things to happen and maybe have one eye on the next game. You've got to look at what's happening now and do things properly and they did that in the second half."
