The following is from a NR by Lumina last summer, the new Northwest zone trends onto CCD ground. These Lumina holes are right on the claim boundary of CCD JV'd claims:

Vancouver, British Columbia -- Lumina Copper Corp. (TSX Venture: LCC) (the "Company") is pleased to announce that it has discovered two new copper mineralized zones at its 100% owned Taca Taca copper/gold/molybdenum deposit located in Salta province, Argentina.

The first zone is located approximately 250 meters northwest of the current National Instrument 43-101 ("NI 43-101") mineral resource estimate and has been defined to date by 24 holes (assay results for 4 holes received to date) over an area of 600 meters in a east/west direction by 600 meters in a north/south direction. The zone is characterized by high grade supergene copper mineralization associated with a broad north/south trending fault zone. Drill results received to date are highlighted by hole RC-19 that intersected 222 meters grading 0.69% copper, 0.13 g/t gold and 0.01% molybdenum (0.83% copper equivalent(1), including 40 meters grading 1.67% copper, 0.38g/t gold and 0.02% molybdenum (2.01% copper equivalent).

There were 3 holes right along the claim boundary and were approximately 300 m apart from north to south.  These 3 holes are literlly a few metres from CCD ground. Go to Lumina website for assay results for all three. All in all this is a new zone discovered by Lumina last summer and expands onto CCD ground. Of particualr interest is the mention of a 600m wide zone. Thats huge and right onto CCD claims. This is what all the excitement is about.
