A substantial metalled trackway runs through the mine area, starting from America Farm at SJ 2130 6085. It passes between large limestone gateposts, likely dating to the 18th century, and appears to have been the main route for transporting ore. The trackway continues eastward towards the road at SJ 2190 6100 and may have once extended further to the Smelter site at East Maeshafn.

A mound to the east of the Youth Hostel, along the Maeshafn to Eryrys roadside at SJ 2095 6055, is possibly the remains of a horse pulley shaft. Nearby, horse whims are located north of the road, overlying the old Jamaica workings. Additionally, a large rectangular pond remains at SJ 2175 6090.

Later mining efforts between 1896 and 1903 were undertaken by Messrs Brunner Mond and Co., but with limited success. Their explorations extended eastward beneath Moel Findeg, incorporating several setts, including Cefn-hir, Lisburn, America, Jamaica, and East Maeshafn.

During this period, the adit level was extended to connect with Cefn-hir Shaft at SJ 2120 6090, located south of America Farm. Lisburn Shaft lay further to the southwest. A sequence of shafts crossed Moel Findeg from east to west, following the course of the Maeshafn Vein.
