WoW! Madeleine the cat has my toung! Just takes my breath away! How could it happen?

Yupers one day it's $3.50 and the next it's off the AMX and a Penney at .19 can they
now trade 5000 share blocks like MDIN? I wonder when or what the low will be
after eveyone averages down for the 3rd. time and the 4th. and 5th.... I like to
stay under a 5th. a DAY it's easer on the liver than the average. hishhhhhhhhh

ya well anyway happy trails to you untill we Day again!

Ooooops I came back to add this !!! What are the rules for AMX and what level
must they stay at to keep there stock on the AMX? can you be in a penney range
and stay there? Now to load this again.

Las Dos Marias: Conclusions and Recommendations: (Part 1)

The geological and geophysical surveys carried out on The Las Dos Marias property have outline a more complicated geological picture than was first envisioned. The geological mapping, both surface and underground have outline a volcanic sequence containing felsic tuffs and laccustrine limestones with horizons of sulphide deposition, both diagenetic as in the pyritic felsic tufss and hydrothermal in the manto deposits of chalcopyrite-pyrite. Geological mapping also discovered a shear zone hosted gold deposit related to both structural control and an intrusive granodiorite dyke, occurring within andesites underlying the volcanic sequence.

The discovery of the granoidiorite dyke within the survey grid dispelled the concept that the manto deposits were related to the Lipangue breccia pipe, but provided a source for both the manto deposits on the east side of the creek and the shear hosted gold deposits on the west side. The relationship of the shear zone to the granodiorite dyke is not clear at the moment. The dyke many have been intruded along the zone of weakness represented by the shear zone, or the shear may have been the feeder zone for the volcanic sequence outcropping on the east side of the creek and was subsequently intruded by the dyke.

The structural relationship of the overlying and underlying massive andesites to the volcanic squence is also unclear. Is it a straight strtigraphic succession or are there unlocated faults separating the different horizons? The geomorphology of the Quebrada Durazno suggests strong structural control by faulting or shearing along the trend of the creek which was more easily eroded than the massive andesites. The volcanic sequence is thought to be an interlude in the andesitic eruptive event when a sedimentary sequence of lacustrine limestones were laid down. This quiescent period of sedimentary deposition included distal eruptions of a felsic nature which led to the deposition of the tuff horizons with the limestone beds. There are both waterlaid tuffs and subaerially deposisted tuffs in the sequence, the pyritic siliceous tuff was more of a chemical sediment derived from hot spring or volcanic fluid emanatins than a subaerial deposit giving rise to the high pyrite content.

The manto deposits or horizons exposed in the underground workings on the east side may represent a volcanogenic sedimentary deposit, or Volcani Massive Sulphide (VMS) deposit or a true "manto" type replacement deposit where hydrothermal fluids have deposited metals held in solution due to the physicochemical changes occurring with distance from the source of the fluids.

Based on the geological evidence it is thought that the manto deposits are true mantos, resulting from the depositon of metals contained n hydrothermal fluids percolating through porous volcanic tuffs and epiclastics within the volcanic sequence. The occurrence of more than one manto horizon in the underground openings is thought to confirm this interpretation.
