done this, i able to clear off their entire base in normal =P, basically this map got a catch, they give you new tech goliath, if you keep building them, will make your mission very difficult, especially in hard, cause your goliath is no way able to do as much damage as their void ray and void ray can shoot further(u dont have the tech upgrade yet, +3/+1range). So you will face heavy loses and alot of resource just making goliath, my suggestion would be ignore goliath, just mass produce marines and heavy marines plus some medic, upgrade weapon/armor as usual, 1 void ray cant kill a single marine if your medic doing their job correctly(i think i had the medic upgrade which makes them more effective at healing and also marine+10hp).

you dont have to rush in this mission, need not to capture any terrazzine mine at beginning, just focus on defending all mine, and destroy their center base. push them all back to their main base, make 2nd army, guard both of their main base exit, keep some distance, they will keep replacing guards if u kill them, so its no ending killing. some probes will try to sneak pass your defense when you fighting with its escorts, so either manually kill them off b4 they run too far, or just put 1 marine at each mine. then its harvest time, send out scv to mine terrazine, you dont need to guard your scv, just make sure nothing get pass your defense.

@PJ that mission where got battlecruiser or banshee? we talking about Welcome to the Jungle leh. You can postpone it that long to do it after the end of the tychus/artifact mission arcs? o_o
