ZEVENWACHT WINE FARM AND TIN MINE

Photo source:  www.zevenwacht.co.za

The tin deposits on the Zevenwacht Wine Estate form one of several hydrothermal deposits associated with intrusion of granite and minor gabbro and diorite of the pan-African Cape Granite Suite with the deposits being concentrated in a northwest-trending zone
between Somerset West and Yzerfontein. Vein-hosted mineralisation is predominant with the veins or lodes trending between northwest and north-northwest.  The veins are both exogranitic, being hosted by the Malmesbury Group metasediments, and endogranitic.

Route from CTICC to Zevenwacht wine estate

On the Zevenwacht Wine Estate and adjacent areas, the veins are endogranitic being hosted by coarsegrained, porphyritic granite named the Spier Granite.  They trend north-northwest within a 500 m-wide zone and the individual lodes are up to 3 metres wide,
dip moderately (20 to 35 degrees) west or east and consist of aplite dykes and irregularly developed quartz veins. Several tin deposits were mined during the early 1900s with those on the Zevenwacht Wine Estate and adjacent areas accounting for the bulk of the production.
