Secondly, are you seriously presenting the idea MDMN and partner are contemplating an open pit mine on the ADL.

Obviously there is a lot more exploration and geological analysis that will be necessary before a determination of that magnitude can be made. However, to completely disregard the possibility of an open pit at Lipangue essentially dismisses the professional opinions of Gordon House, P.Geo (dec.), ACA Howe and the conclusions of Sepulveda Clemente Perez in his report on the property, among others.

After all, the two main selling points of Alto de Lipangue are:

1) Its low elevation and proximity to mining infrastructure which translates to lower CAPEX...certainly an attractive feature given the current mining economy.

2) The indication based on geological data and professional opinion so far is that ADL houses one or possibly two copper porphyries as suggested or bluntly stated by multiple geologists who have visited the property and/or professionally analyzed the geological data that is available.

Copper porphyry deposits are most often mined as open pit operations. Porphyry's size, the overall lower grade of the mineralization and the proximity to surface all lend itself to the economies of scale that open pit mining affords. 60% of all copper mining in the world is extracted by open pit techniques, so the obvious deduction is that if ADL is determined to house one or more copper porphyries of economical grade, then the logical next step is the extraction consideration which obviously leads to an open pit.

In ACA Howe's report, they state the following:
"Medinah’s Lipangue and Dos Marias Properties represent excellent targets to host large tonnage, bulk mineable gold and/or copper (+/- silver) mineralization at relatively shallow depths, and these targets remains open in most directions and could be larger in extent than currently exposed. All of the targets have only been tested on an preliminary basis and Medinah believes that with a minimal exploration program the potential size of these prospects can be substantially increased."

Yeah, so I don't believe it's a stretch at all that parties evaluating the ADL claims group have the idea of an open pit in the back of their mind...even if the reality of that notion is several thousand of meters in exploratory drilling and a good number of years away.
