Golden Deeps (ASX:GED) said new soil and rock chip results have extended the copper, silver, zinc, lead, germanium, and antimony mineralized corridor at its Graceland prospect in Namibia, according to a Thursday Australian bourse filing.

The new rock chip sample results include 3.12% zinc, 1.94% lead, and 46.5 grams per tonne silver, 0.4% copper from a further 500 meter northeast strike-extension of the Graceland mineralised corridors.

The Graceland prospect is located within the company's 440 square kilometer tenement holdings within Namibia's world-class Otavi Mountain Land Critical Metals Belt.

The company said it has acquired detailed aerial satellite imagery and elevation data over the Graceland area, which will be integrated with rock chip and soil results and inversion modelling of any anomalies generated by the induced polarization survey to define drilling targets for high-grade, "Tsumeb-style" sulphide deposits.
