Difficult to say whether its the price(drop) of copper thats the catalyst or not as you asked regarding copper and some of the plays breaking down severely.It should be noted in tko's case,it has 90% of its production hedged til the end of 2012.I thought the hedge was what was holding back the stock when even prosperity news came out.Hedge seems like a brilliant move now and yet it still gets hammered.See nr below.

TASEKO ENSURES MINIMUM REVENUE STREAM FOR THE NEXT 18 MONTHS
6/28/2011 4:30 PM - Canada NewsWire

VANCOUVER, Jun 28, 2011, 2011 (Canada NewsWire via COMTEX News Network) --

Taseko Mines Limited (TSX: TKO) (NYSE Amex: TGB) ("Taseko" or the "Company") has purchased put options on approximately 90% of the Company's 2012 copper production, which ensures a minimum selling price of US$3.50 per pound. The puts were financed by selling funded calls at an average strike of US$5.07 per pound at a cost of US$0.10 per pound.

Russell Hallbauer, President and CEO of Taseko, stated; "This hedge transaction was implemented to mitigate margin risk, as we have seen ongoing volatility in commodity prices over the past six months causing heightened concerns on copper price stability. The 2012 put options, combined with the remaining 2011 put options, guarantees the Company's revenue stream for the next 18 months. This security allows us to bridge into Taseko's roster of future opportunities without the risk associated with a significant reduction in copper prices."

Mr. Hallbauer continued, "With numerous near-term projects in the pipeline, including Gibraltar Development Plan 3, advancement of the New Prosperity Gold-Copper project and completing the feasibility level evaluation of our Aley Niobium project, we believe it is prudent to secure the revenue stream on our Gibraltar production to ensure these opportunities can be fully realized."

During the second quarter of 2011, procurement and detailed engineering began on Gibraltar Development Plan 3 (GDP3). The CDN$325 million capital project will result in a 90% increase in annual copper capacity at Gibraltar to 180 million pounds and a 70% molybdenum production increase to 3 million pounds annually by 2013 (75% to Taseko's account).

In early June the New Prosperity project description was submitted to the Federal Government. The Company expects the Canadian Environmental Assessment Agency (CEAA) to proceed with the formal environmental assessment process for New Prosperity in the near future.

In addition, Taseko's management team is also focused on expediting the Aley Niobium Project. In the next six months, the Company's objective is to convert to a measured and indicated resource and have a feasibility study at or near completion.
