As far as the resistivity testing goes: For Gold-Copper prophhyry deposits: "Ore zones, particularly those with higher Au content, can be associated with magnetite-rich rocks and are indicated by magnetic surveys. Alternatively the more intensely hydrothermally altered rocks, particularly those with quartz-pyrite-sericite(phyllic) alternation produce magnetic and resistivity lows. Pyritic haloes surrounding cupriferous rocks respond well to induced polarization(I.P.) surveys but in sluphide-poor systems the ore itself provides the only significant IP response. Porphyry deposits are marked by large-scale, zoned metal and alteration assemblages. Ore zones can form within certain intrusive phases and breccias or are present as vertical 'shells' or minieralized cupolas around particular intrusive bodies. "

HI Handshake. How long does it take, I don't know I'm open to a time schedule here. I would guess if road work is completed this week, by next end of next week beginning of Sept. we should have the results. They also do (as my geologist friend has told me) some IP resistivity, and other geology mapping. Maybe the Chief could help us with this???? A drill can drill porphry at approximately 70 metres a day. That is the standard acceptable rate for NQ diamond drilling! The average 4000 metres of holes costs about $400,000US. Core logging and sample preparation costs about $15,000US (4000 metres) Assaying is an unknown, because of location and shipping costs as well as security of the core sample. My unknown (at this point) is whether a road must be built to get to the target areas. 20 kilometres of "bulldozed roads in Chile" can run about $100K without blasting. Induced Polarization(IP) survey over the breccia zone costs about $70,000US So extrapolating backwards $70K IP 100K road $15K preperation $15K (unknown) $400K drilling (US 100/metre) including mobilization and bit costs ___________ $600K Timeline From the time samples are prepared and arrive assayer to the time a company issues a newsrelease regarding assay results, rarely occurs within 6 weeks. The industry average appears to be about 2 months!!! The reason is that all the samples are sent at once, as opposed to being shipped as they drill! The Breccia cap is normally a two-dimensional size that "MAY" be able to two-dimensionalize the copper/gold porphry below it!! Therefore two things can interfere with the "discovery" A) the amount of overburden! This is extremely important the breccia cap maybe 200 metres below the surface, the copper/gold porphry (if it exists) may be 100 metres below that!! B) the thickness of the breccia cap and its content. If the breccia cap is not mineralized and 200 metres thick, the total overburden (200 metres overburden, 200 metres breccia=400 metres) makes the project "TOAST" unless chalcopyrite is hit in significant intersections!! Obviously as a pessimist when it comes to exploratory programs I have given you worst possible scenario in A and B above!! A)The Best is a thin mineralized breccia at surface with a copper/gold porphry exactly the same size (one foot below the breccia) as the properties square area under option! B) A fully mineralized breccia and copper/gold porphry at surface, with a natural swaled out piece of rock, forming a perfect trough,that listfully runs to the bottom of the mountain, where there is, an abandoned perfect condition ore processing plant for sale at fire sale prices!! My impression is that 80% of the people on the MDIN thread will go with the latter A&B as being highly possible and probable!! the Chief
