As part of the lease negotiations, the Bute Estate put forward arguments to support their requirements in that a lot of money had been spent by them on High Court summonses to resolve boundary disputes, one of these being the case of 30 acres stolen from the Bedwellty Common by the owners of Cwmllwydrew Farm.

Eventually two separate leases were agreed upon. The first covering the coal under the Tyla Du Farm which would be worked from Fochriw Colliery and the second covered the remainder which would be worked from the new colliery which was shown on a plan (Where is the location?)

In 1886 the requirement for a new colliery was being discouraged since the shaft depths would have to be 1500 feet to exploit the seams below the Brithdir and costs of between £120,000 and £130,000 were mentioned.

During 1887 it was discovered that D.I.C. had not left a barrier between their workings to the north west of Fochriw and those of the Rhymney Iron Company and negotiations were being mooted to try to obtain agreement with the R.I.C. for them not to mine to their boundary thus leaving the barrier on their side. The barrier was important to prevent any breakthrough of water from one concession to an adjacent one.

In 1886, D.I.C. again reported that Bedlinog Colliery was unsatisfactory and as hopeless as ever and several of their other collieries were rapidly approaching exhaustion
