The gold deposits of the farms Lisbon and Berlyn in the Eastern Transvaal by V. C. H. R. BRERETON* (Visitor) SYNOPSIS This paper describes the discovery and recovery of gold, over a period dating back to the 1870s. on the farms Lisbon and Berlyn, situated approximately 1I km north-east of Pilgrims Rest. where mining ceased in July 1971. 99 years after gold was first discovered in the Pilgrims Rest and Sabie districts. Included in the paper are accounts of the discovery and mining operations of the Lisbon-Berlyn Company from 1884 to 1890. The operations of small companies and syndicates. the superficial winning of gold by diggers, and the encouraging reports of four mining engineers in 1890 are also mentioned. SAMEVATTING Hierdie verhandeling beskryf die ontdekking en herwinning van goud oor 'n tydperk wat strek vanaf die sewentigerjare van die vorige eeu, op die plase Lisbon en Berlyn, ongeveer I1 km noordoos van Pilgrims Rest waar mynbou in Julie 1971,99 jaar na die eerste ontdekking van goud in die distrikte Pilgrims Rest en Sabie, gestaak is. Die verhandeling sluit verslae oor die goudontdekking en die mynboubedrywighede van die Lisbon-Berlyn Con;- pany van 1884 tot 1890 in. Daar word ook melding gemaak van die bedrywighede van klein maatskappye en sindikate, die oppervlakkige winning van goud deur delwers en die bemoedigende verslae van vier myningenieurs in 1890. INTRODUCTION As shown in Fig. 1, the farms Lisbon (531KT) and Berlyn (506KT) are situated 8 km north of Graskop at an altitude of 1370 m. Graskop township is located at the terminus of a 123-km-Iong railway running northwards from Nelspruit. The country is very beautiful and the climate healthy, and there are large timber plantations and an abundance of clear water. The Lisbon Falls, with a drop over two stages totalling approximately 90 m, are situated on the Waterfall River, which tra verses the two farms (Plate I). Approximately 1 km below the falls, on the left side of the river, is a cave. A Mr Billy Davies, whilst prospecting on the farm Lisbon and the adjoining farm Berlyn, fled from some hostile natives and hid him- self in the cave, which he subse- quently fortified against any attacks. This portion of the cave and the fortifications can be seen today. Davies' prospecting activities led to the discovery of what has been described as 'a wall of gold'. The locality is in the vicinity of a large belt of leaders, the latter covering an *Government Land Surveyor, retired.
