Udu Mine


The Udu deposit was discovered in 1957 and was developed in the late 1960’s. The mine operated for one year with recorded production totaling 32,435 tonnes of selectively mined material assaying 5.9% copper (“Cu”) and 6.7% zinc (“Zn”). Records indicate treatment on site yielded 5,524 tonnes of concentrates, assaying 18.3% Cu, 1.65g/t gold (“Au”) and 192g/t silver (“Ag”).

The mineralisation consists of a cluster of VMS (Volcanogenic Massive Sulphide) lenses with an overprint of epithermal base metal mineralisation.

Subsequent phases of historical exploration within the Udu Project area largely focused on the immediate Udu Mine area.  Historical regional exploration was limited.   No drilling had been conducted away from the Mine area until Dateline commenced exploration drilling on regional targets in 2012.

Current Exploration

Since 2006 Dateline has conducted resource drilling at the Udu Mine, initiated a program of regional exploration which included blanketing the tenements with a VTEM airborne geophysical survey in 2010 and a 685 hectare 3DIP survey in 2013.

Drilling in 2008 culminated in a JORC compliant inferred resource estimate of 4.53 Million tonnes (“Mt”) averaging 3.9% Zn, 1.2% Cu, 0.14% Pb, 0.26g/t Au, 29g/t Ag and 635ppm As using a 0.5% Zn cut-off.  

Regional exploration has defined a number of targets with strong geochemical and geophysical signatures.  These range from VMS/epithermal targets with affinities to the Udu Mine to deeper Porphyry Copper targets.

Exploration Strategy

Datelines exploration strategy is a four pronged approach;

  • Udu Inferred Resource
    • Scoping Study underway due for completion Q2 2014
  • Near Resource Targets
    • Potential to significantly expand on VMS/epithermal resources.
  • Porphyry Copper Targets
    • Immediate priority the Nagasauva 3DIP target.
  • Greenfields Porphyry Copper Exploration
    • Field work and ground geophysics to commence on greenfields targets in 2014.
