Since he is extending the circuit he MUST have a 4-wire circuit. We are not allowed to extend an older "3-wire" (without ground) dryer or range circuit.
jcorbin, if you DO have a proper 10/3 w/ground cable you can extend it, BUT the junction box MUST remain accessible. From your description I get the idea that you are going to put the sheetrock back up once the splice is made. This is a BIG no-no.
