The Haphazard Co took the lease on the second leg in 1863, a shaft was sunk near the gardens entrance. The lead proved very rich from this point with yields exceeding 150 oz per week. Other companies sunk shafts in the same area in an attempt to find the lead higher up. The Wombat Hill Co continued to work their branch into Wombat Hill. After crossing Daly street they encountered a basalt wall.
Volcanic experts believe it to be an old volcanic plug.
The miners attempted to go over the wall. They were at a depth of 230 feet and tunnelled up 170 feet without finding the top. The lead was followed to the NE corner of the gardens. The Royal Oak Co. took over at this point as they already held leases in the area. In 1864 the lead was worked onto Stanbridges Pre-emptive right land.
