FOREWORD

This publication contains the proceedings of a workshop convened by
the International Seabed Authority on mineral resources other than
polymetallic nodules, to be found in marine areas beyond the limits of
national jurisdiction (the Area). It is the third in the series of workshops that
have been convened by the International Seabed Authority to inform the
international community of scientific and technological developments that are
taking place with regard to marine mineral resources. In 1998, at the resumed
Fourth session of the Authority, the representative of the Russian Federation
made a request to the Authority to adopt rules, regulations and procedures
for exploration for seafloor massive polymetallic sulphides deposits and
cobalt-rich manganese crusts. To prepare the Authority for work in this
regard, it was decided to convene this workshop on the future development
of minerals other than polymetallic nodules in the Area. It was decided at the
outset that a comprehensive effort would be made to obtain information and
understanding on the present knowledge base for the possible exploration
and exploitation of these other resources, in particular seafloor massive
polymetallic sulphides deposits and cobalt-rich ferromanganese crusts. It is
recognized that while a good deal of scientific research has been
accomplished, the transition from marine scientific research to prospecting
and exploration for these resources, and then to their commercialisation will
require a certain amount of flexibility in rule making.

To date, the work of the Authority has focused on the exploration for
deep seabed polymetallic or ferromanganese nodules that are to be found in
the international area. Under the parallel system prescribed for deep seabed
polymetallic nodules, a prospector who seeks an exploration contract from the
Authority is to submit “an application that covers a total area, which need not
be a single continuous area, sufficiently large and of sufficient estimated
commercial value to allow two mining operations. The application shall
indicate the coordinates of the area, defining the total area and dividing it into
two parts of equal estimated commercial value and shall contain all the data
1/
available to the applicant with respect to both parts of the area” .

INTERNATIONAL SEABED AUTHORITY 1
The Authority designates one of two areas as reserved area for
exploration either by its operating arm, the Enterprise, or by the Authority in
association with developing States. The other area is allocated to the
applicant as a contract area.

For deep seabed polymetallic nodules that lie on and in sediment that
covers the seafloor in the abyssal plains of the world’s ocean, this requirement
has worked and seven entities have obtained exploration contracts with the
Authority under that system. Given the difference in the nature of the
deposits, a fundamental question for consideration is whether the parallel
system will work for seafloor massive sulphides and ferromanganese crust
deposits. Would work done during prospecting be sufficient to delineate two
seafloor massive polymetallic sulphides deposits or two cobalt-rich
ferromanganese crust deposits of equal estimated commercial value? Should
a different system be devised to meet the objective of the parallel system that
was based on the principle that there should be opportunity for all to
participate in the exploitation of the mineral resources in the Area?

Based on the need to provide the international community with a
response to these and other related matters, the workshop was convened with
the following objectives:

(a) To obtain information and understanding on marine minerals of the
Area for which rules, regulations and procedures for prospecting,
exploration and exploitation are yet to be adopted by the Authority,
with an emphasis on seafloor polymetallic massive sulphides and
ferromanganese crust deposits; and in the case of the latter two
deposits,

(b) To obtain information on their distribution, the marine environment
where they are found, metals of commercial interest, resource
potential and developments with regard to research and exploration
for these deposits.

The workshop also addressed the nature of regulatory regimes in
some countries that have established marine mineral industries. This was
