Both ZFX and MMG spent a good deal of funds of exploration drilling, remember ZFX was swimming in cash for a few years knowing the limited mine life of century. You are right, the juniors do tend to be more nimble and clever with exploration however i think its unlikely there is another easy to find open pit century type deposit on the AYA leases. Could they piece together a number of smaller discoveries? MMG have already covered their commitment to mine closure, have to by law. Huge leverage to exploration and zinc prices are the key, but its not a quickly turn the lights back on asset at any zinc price for me.
