A case study for Rosia Montana Mining Landscape:
To give a piece of background information, the main threat to
Rosia Montana Mining Landscape is due to a planned massive
open-cast mining project pursued by RMGC, owned 80% by Gabriel
Resources, a Canadian-based company, and 20% by a Romanian State
mining company, to explore “the largest undeveloped gold deposit in
Europe”. Despite some efforts on their side to conserve historic
sites (often badly implemented from a conservation standpoint),
such large-scale open cast mining would unavoidably destroy large
parts of what specialists consider a unique historic mining
landscape of national and European importance.
Modern mining technology, being based on the systematic use of
cyanide, would also trigger major pollution problems, and this even
more as the mining exploration was to be finished within some 18
years, leaving the practical management of toxic sludges and
deposits thereafter all the more uncertain.
Also, the limited mining duration, and its likely leftovers,
could not have provided a sustainable development base for the
rather poor region in the longer term.
According to this study, what can be a good development strategy
and management plan for this mining site?
