Provided that if two reefs, lodes, veins or mineral beds or deposits are so situated in relation to each other that the parting between workings made therein is less than ten meters at any place, such workings shall also be shown on a combined plan or longitudinal section, as the case may be, in different colours.
(4)
The plans kept under clauses (a) and (e) of sub-rule (1) shall also show the settled boundary of the mining lease, or where the boundary is in dispute, the boundaries claimed by the holder of the mining lease and by the holders of the mining lease adjacent to the disputed boundary:
Provided that where it is not possible to show the complete boundary of leasehold on the same plan an additional key plan on any other suitable scale showing such boundaries and the outline of the workings shall also be maintained.
(5)
