Last year, CUU announced a delay on the resource estimate around the same date (March 24th) and Feasibility was expected in the summer (June early July).

But still that didn't stop the share price from reaching $2.75 30 days later....

Copper Fox Announces Strategic Acquisitions to Enlarge Schaft Creek Property and Purchase of Liard Copper Mines Ltd. Shares

Resource Estimate:

AMEC has advised that the resource estimate originally scheduled for completion at the end of March has been temporarily delayed. Copper Fox is working with AMEC to resolve database issues identified during the data verification. AMEC have established there is an inconsistency between the silver analysis of core samples analyzed by Asarco, Hecla, Teck and Copper Fox over approximately 60 years of exploration on the Schaft Creek property. The inconsistency in the silver concentrations may require that the silver content of the mineralization not be reported in the pending resource estimate which is expected before the end of April, 2011. Mr. Stewart stated "the majority of the data from the Schaft Creek deposit was collected before 1985. The issues we are dealing with are typical of deposits with a considerable amount of historical data where verification of the historical data is challenging. Re-sampling of between 5% and 10% of the historical core (approximately 3,000m) combined with a geostatistical analysis of the silver data base will be required to obtain the confidence necessary to estimate the average silver content of the mineralization. This work is expected to commence in mid May 2011 in conjunction with the start of the planned 2011 diamond drilling program. On completion of the re-sampling and 2011 diamond drilling program, the resultant data will be included in an updated resource estimate.

The re-sampling and additional diamond drilling proposed above would not affect the completion date for the feasibility study on the Schaft Creek deposit which is expected to be completed either by the end of June or early July.
