The dimension stone industry in Namibia has been in existence since the earlyyears of this century, however its potential has not yet been fully developed.Namibia should use its varied geological environments to continue takeadvantage of this opportunity. Namibia�s complex geological history,especially in the central portions of the country, have given rise to a varietyof metamorphic and tectonic environments that have formed rock types suchas marbles, calc-silicates, carbonatites, granitiods and mafic intrusives thathave unique colours and textures (e.g. banding, folding, brecciation) that haveenormous potential as dimension stone.

Although annual production of marble and granite has only shown a slightincrease in tonnage produced since 1993, averaging 13 750 tons of marbleand 6 200 tons of granite per year, there has been an increase in the rangenow available. This is mainly due to the upswing in dimension stoneexploration in Namibia, with 32 new Exclusive Prospecting Licence (EPL)applications having been received since 1994 (16 in last year alone), bringingthe total number of EPLs to 48. Over the same period, two new MiningLicences for dimension stone have been granted and three applications arepending.

Modern quarrying and processing machinery and techniques have beenintroduced over the past fifteen years. Modern quarrying techniques nowemployed in Namibia include diamond wire and chain saw cutting for marbleand flame cutting for granite. Marmorwerke Karibib has installed a fullyautomated and computerised tile cutting and polishing plant.

Good intrastructure such as roads, rail links and habour facilities areavailable. Electricity and water can be obtained, even in the remotest partsof the country.

An Untapped Potential

Page 1of 4

Currently the majority of Namibia�s dimension stone production is exportedas blocks and this trend will continue for the foreseeable future as thepremium prices paid for first grade blocks will ensure that these will alwaysbe exported. Second grade blocks have the potential to be used as feedmaterial for further local processing plants producing high qualitypolished slabs and tiles for the international market. The economic viabilityof such a processing plant that is not linked to a quarrying operation wouldbe enhanced by acquiring Economic Processing Zone status, due to the taxincentive and other advantages.

Any waste material can be used by labour intensive, low technologyoperations manufacturing paving stones, curbing and gate posts or as feedfor small, mobile stone crushing plants. these possibilities could providemuch needed employment while helping rehabilitation by clearing the waste.

The ornamental use of dimension stone is largely ignored in Namibia and thisshould be developed. The production of columns, table tops, gardenfountains and suchlike would add value. Likewise, the use of marble andpyrophyllite, as examples, for statues and carvings would be a hit withNamibia�s burgeoning tourism industry.

Namibia�s internal market for dimension stone is small being limited mainly totomb stone manufacture with the occasional building cladding/flooringapplication. Regionally, Namibia exported 11.6% (1603t) and 18.4% (1228t) ofits 1997 marble and granite production respectively to southern Africancountries, mainly South Africa. With the opening of the Trans-Kalahari(through Botswana) and Trans-Caprivi (to zambia and zimbabwe) highways, thepotential for developing markets for processed slabs and tiles to othersouthern and central african countries has become a reality.

MarbleMarmorwerke Karibib historically has produces a dark grey tightly foldedmarble with alternating white and grey to dark grey layers (Zebra, CapraBlack) from Capra Hill, 3-km northwest of Karibib, a white marble (KaribibWhite) from Town Quarry, 5 km southeast of Karibib and Esserando, a pinkyellowish marble from Dernberg Hill situated 10 km west of karibib. Recentlya calc-silicate marble that contains dark green serpentinite grains withinwhite to cream coloured carbonate matrix (Namibian Green, Namib Harlequin,Desert Green) is exploited just north of Nonidas, 10-km east of Swakopmundwhile White Rhino, a white marble is quarried 20-km south of Karibib.

Aus Marble (Pty) Ltd quarries the Potoro Leonardo variety, a brecciated blackmarble with a golden yellow matrix, 100-km south of Aus.

Two new comers into the market are Okatji Marble (Pty) Ltd and EtusisMarble (Pty) Ltd. Okatji Marble (Pty) Ltd has developed a quarry some 10-kmeast of Karibib to produce Namibian Rose and Okatji Rose from an off whitemarble containing various amounts of pink tremolite. Several white, nearwhite and banded white marbles are being tested for exploitation by EtusisMarble (Pty) Ltd on the farms Etusis and Kubas, 30-km south-west of Karibib.

The Palissandro Marble (Pty) Ltd is situated some 45 km southwest of Karibibon the farm Gamikaub West. Five different marbles are produced. a greyish-white (African White) uni-coloured fine-grained marble, a white marble withlight green schlieren (African Green), a greyish-green marble with occasionallight brown streaks (Namib Desert), a light yellowish-brownish bandeddolomitic marble (Light Palissandro) which grades into a greyish-brown in-tensely folded variety (Dark Palissandro).

Namibian Varieties

Page 3of 4

Granite Marmorwerke Karibib quarries a medium to coarse grained, equigranulargranite near Spitzkoppe. The white variety is known as Namibian Pearl, theyellow as Tropical Sun and the light brown as Kalahari Sand. Thierportfolio also includes Guldenrot, a deep reddish brown, medium to finegrained, equigranular alkali-granite in the Okahanja District; Ubib, a coarsegrained red pegmatitic granite with a slightly porphyritic texture; and GoasWhite, a uniform textured whitish-grey coarse-grained slightly porphyriticgranite, both occurring south-west of Karibib. Omenje Black, a fine to medium grained dolerite with a greenish-black colour and ophitic texture isquarried south-east of Omaruru.

Damara Granite (Pty) Ltd markets a yellowish-brown granite quarried nearRooikop, 15-km east of Walvis Bay.

Marlin Granite Namibia (Pty) Ltd has been investigating a light green granitegneiss with red garnet porphyroblasts occurring 12-km southeast of WalvisBay and a pinkish-yellow porphyritic granite at Okombahe, 16-km east of Uis.

Namstone (Pty) Ltd is exploring a course-grained red granite on the farmRietkuil, Opuwo district, a light grey to white granite on Etendero 95 and apink porphyritic granite on Morewag 480, both in the Omaruru district.

OtherAfrican Blue is quarried from sodalite and ankerite bearing carbonatite dykesoccurring some 10-km west of Swartbooisdrif, 4-km south of the Kunene Riverby Namibia Blue Sodalite (Pty) Ltd.

Namib Aragonite which occurs as white, yellow and light brown bandedvarieties is found in the desert near Namib Lead Mine, 40-km northeast ofSwakopmund is exploited by Marmorwerke Karibib.
