Identification of Anomalous Germanium in Ore at Citronen
Identification of Anomalous Germanium in Ore at Citronen
Perth, Dec 7, 2017 AEST (ABN Newswire) - Ironbark Zinc Limited (Company) (ASX:IBG) advises that during ongoing metallurgical testwork a composite ore sample, see Figure 1 in link below, considered representative of the Beach Zone ore body of mineralisation was assayed, for the first time, for germanium (Ge) and returned an anomalous result of 24 parts per million (ppm). Germanium is known to replace zinc in the sphalerite (zinc sulphide) lattice in some zinc ore bodies and is generally observed, where mined, to report to the processed zinc concentrate where the grade is likely to increase pro-rata with the zinc grade. In the Citronen project the zinc is generally upgraded between 8 and 9 times to a predicted 53% zinc in concentrate grade.

The potential grade, continuity or value, if any, of any germanium is currently under investigation and will be reported in more detail in due course.
