It's possible they may be planning a La Yesca NR in the near future and don't want to comment at this time, but.... I did some digging last night and found this June NR with an update on La Yesca

I just wanted someone to elaborate on the problems. They should be able to discuss a topic that has already been publically disclosed.

excerpt:

The Company remains committed to achieving successful commercial production at its tailings operation at La Yesca as one of the key goals going forward. Although we have not yet commenced commercial production the company has been actively pursuing further testing of grade, recoveries and grind solutions. The processing facility has been on care and maintenance since the test production runs of November and early December 2008 which provided results that were not profitable due to lower than expected grade and to course a grind.

Beginning in January 2009, MAG Laboratories of Tucson, Arizona were commissioned to conduct recovery testing on our tailings while simultaneously the tailings pile itself was being excavated, tunnelled and assayed to better reassess the grade of the tailings stockpile. We also have been actively reviewing and analyzing a previous successful test recovery process developed by SGS Laboratories in Durango, Mexico.

The tailings pile has now been modeled using data from the 600 samples that were recently collected and assays have been conducted both by our in-house laboratory as well as SGS Laboratories in Durango and IPL Laboratories in Vancouver. As a function of the modeling process it was also observed that the La Yesca tailings pile has an estimated non 43-101 compliant 310,000 tonnes rather than the previous 43-101 compliant (Jim Burns 2007) estimate of approximately 225,750 tonnes.

The result of all the process tests and the tailings pile assays has provided a verified solution to what we believe will be a commercially viable tailings operation, as per the original plan, for four to five years. However, the mill will require some modification and UC is presently seeking hard dollar funding and/or a joint venture partner to complete the upgrade to the mill and start the re-commissioning process leading ultimately to full production. The larger ball mill to meet better grinding targets has already been purchased but is not yet on-site or installed.
