Making Cannabis Oil with Buds and Hash?

I have a question regarding the usage of a dime of pure headie nuggets, and a gram of OG Kush hash. Will the hash be soluble in the oil, or in other words will the THC be extracted from the hash? I have been using the method of 1/3 cup of oil to an 1/8 of chronic buds (Let that sit on medium heat, just simmering for about 30-45 min)i then put that into a batch of 12 muffins. They turn out phenomenal almost most every time...but will it be different using hash?

It must work fine... in fact, using hash is even better than using bud, as hash has more THC than buds.
