A C A Howe Report Summary: medinahmining.com I have taken a look at the A. C. A. Howe report-what follows is highlights of NEW information from the report which I had not seen before in any other report or had forgotten about. A.) "Howe was retained by CDI in June, 1999 with the terms of reference for this assignment consisting of a qualifying geological report complying with reporting guidelines as set out in proposed National Instrument 43-101(scheduled to replace National Policy 2A), and covering the mineral potential of the Lipangue and Dos Marias Properties. It is Howe's understanding that this report is required by CDI as part of a 15C211 filing with the NASDAQ Stock Exchange.? ANYONE KNOW WHAT 'CDI' IS? MY GUESS IS CDI IS THE NAME OF MEDINAH'S AUDITING FIRM. B.) "The Lipangue Property consists of a total of 5 claims (3 mensuras and 2 pedimentos) covering 1,363 hectares. The Dos marias property consists of one "mensura" (mining claim), which covers a total of roughly 130 hectares." IN CASE YOU DIDN?T KNOW-A HECTARE IS 2.47 ACRES-THUS LIPANGUE IS ABOUT 5.2 SQUIRE MILES IS SIZE-LDM IS ABOUT « A SQUARE MILE. PART OF THE LIPANGUE CLAIMS ARE NOT FULL BLOWN MINING CLAIMS-"PEDIMENTOS". THESE ARE THE NEW STAKED CLAIMS NEXT TO THE ORIGINAL CLAIMS-THEY PROBABLY WILL NOT BE TURNED INTO FULL BLOWN CLAIMS UNTIL THE EXPLORATION PROGRAM SHOWS THAT THEY HAVE MERIT. C.) "Typical of hydrothermal breccias, the down plunge extend could be very deep and possibly overlie a larger porphyry style minerlized system at depth." AMEN! D.) "Additional isolated small outcrops of breccia occur along the southern edge of the area mapped by Medinah. These exposures are completely surrounded by rubble and overburden and the actual size could be larger. In addition, they occur beyond the southern extend to the recent IP/resistivity survey and as such remain untested targets...Future geophysical program should be extended to the south to cover these outcrops.The first documented exploration program over the Lipangue Property, that Howe is aware of was completed by Shell in 1985....by Alejandro Faunes over a 5 day period?\..Additional sampling south of the breccia along the southeast edge of the plateau yielded additional anomalies of gold, copper and silver, but the values and locations of these samples were not documented in the report reviewed by Howe." SOUNDS TO ME THAT THE SIZE OF THE BREECIA IS MANY TIMES WHAT IS EXPOSED AT THE SURFACE-ESPECIALLY TO THE SOUTH AND EAST OF THE PRESENT SURFACE EXPOSURE-RECALL THAT FROM THE DRILL PROGRAM-THE BRECCIA PLUNGES SOUTH AND EASTWARD. THE EDGE OF THE PLATEAU IS SEVERAL HUNDRED METERS SOUTH AND EAST OF THE LAST DRILL PROGRAM-I WONDER WHAT THE NEW IP DATA TAKEN RECENTLY BY GEODATOS WILL SHOW? E.) "The shear roughly follows the based of Quebrada Durazo, and within the property boundaries can be traced over a strike length of about 700 meters(traced through surface outrcrops, diamond drill holes, and extrapolated along strike through IP/resistivity results.)" SHEAR ZONE AT LDM APPEARS TO BE 700 METERS LONG-AT LEAST THE PORTION ON MEDINAH'S CLAIM. F.) "The strongest, and best mineralized portions of the shear zone appear to be hosted in the eastern, or hanging wall portions, and the intensity and gold grades appear to drop in the footwall sections...the location of these holes was found to be collared in the shear zone, therefore missing the hanging wall and possibly the strongest minerealized portion of the auriferous structure." THE TOP PORTION OF A LAYER OF ROCK THAT DIPS AT ANGLE TO THE GROUND IS THE HANGING WALL-THE BOTTOM IS THE FOOTWALL-LOOKS LIKE THE PREVIOUS DRILL HOLES PROBABLY MISSED THE REALLLY GOOD STUFF AT LDM. G.) "..on the east side of the creek (the side closest to Lipangue), has revealed that the individual mantos are not more than a few metres in thickness, but are vertically "stacked" throughout the stratigraphic sequence, the true thickness of which has yet to be determined..potentially bulk mineable copper resource exist here. ..It is suspected that granodiorite that oucrops south of the property, or a late stage intrusive phase at depth could be the driving force of the mineralizing system, however it has also been suggested by medinah that the breccia at the Lipangue Property could somehow be genetically related to mineralization at Dos Marias. A great deal more work will have to be completed, before these can be validated." THE GOLD BEARING SHEAR ZONE IS ON THE WEST SIDE OF LDM IT DIPS TO THE WEST-THE MANTOS DEPOSITS ARE ON THE EAST SIDE OF LDM-THEY DIP TOWARDS THE EAST-TOWARDS LIPANGUE-HOWE THINKS THEY ARE COPPER MANTOS-IT IS UNCLEAR WHAT THE SOURCE OF MINERLIZED FLUID WAS FROM-MAYBE FROM LIPANGUE UNDERLYING INTRUSIVE OR THE INTRUSIVE FOUND LOCALLY AT LDM-INTERESTING. STILL NOT CLEAR TO ME WHETHER A COPPER OR GOLD PORPHYRY UNDERLIES LIPANGUE. H.)"19 confirmation type samples were collected from the two properites...During future drill programs, Medinah should consider using a larger diameter core to get a more representative samples. Howe feels confident that the analytical values reported by Medinah from their recent drilling campaigns over both the Lipangue and Dos Marias Properties give a general representation of the values that can be expected from these properties...In addition, a full quality assurance program should be adapted by Medinah for all future exploration programs to minimize unavoidable sample assay errors which are introduced by the acts of sample collection, sample preparation and assaying." I GOT THE IMPRESSION THAT HOWE WAS NOT IMPRESSED WITH MEDINAH'S QUALITY ASSURANCE PROGRAM FOR THE RECENT DRILLING-NEVERTHELESS-HOWE THINKS THE NUMBERS WERE FAIRLY ACCURATE-PART OF THE PROBLEM WAS THE SMALL DRILL CORE SIZE-THE LOWER VOLUME OF MATERIAL GIVES YOU LESS OF A REPRESENTATIVE SAMPLE-RECALL THAT MEDINAH USED A BUDGET DRILLING RIG OUT OF SANTIAGO-TO DO IT RIGHT WE NEED A BIGGER RIG! I ALSO GOT THE IMPRESSION THAT HOWE PROBABLY WAS PITCHING TO DO THE QUALITY ASSURANCE PROGRAM FOR MEDINAH-THOSE CONTRATORS-THEY ARE ALWAYS AFTER YOUR MONEY! I.)"Medinah's land position is secure, in that it covers the strike and down dip extend of all of their defined mineralized zones and leaves sufficient ground to define new targets along strike or on other parts of the property." I TEND TO DISAGREE-I BELIEVE THAT MINERLIZATION FROM BOTH LDM AND LIPANGUE WILL END UP EXTENDING OFF CLAIM. I GUESS MEDINAH CAN?T OWN ALL OF CHILE! J.)"A 400 metre long, E-W oriented dirt air strip straddles the eastern boundary of the Lo Amarillo claim of the Lipangue Property. Although it is not maintained, it appears to be in relatively good shape and with minimal care small planes could easily land there now." I SEE OPPORTUNITY HERE-PERHAPS MEDINAH'S NEXT SPIN OFF-QUIJANO AIRLINES-WE COULD HAVE A STRANGLE HOLD ON COMMUTER FLIGHTS FROM LIPANGUE TO SANTIAGO! :) K.) "Numerous quartz-epidote and quart-tourmaline veinlets were mapped on surface in the andesite on Line D, just west of the breccia outrcrop, possibly indicating the surface expression of breccia mineralization at depth." BRECCIA APPEARS TO EXTEND WEST OF THE PRESENT SURFACE EXPRESSION-BUT AT DEPTH. L.) "To the North of the underground workings the vein does not outcrops, and if projected, would cross Cerro Dorado?s property boundary onto Medinah's Lo Amarillo claim just west of the Fortuna workings. Old reports from the Fortuna Mine state that the vein is cut off to the northwest by a "mafic unit", however Howe believe that this may actually be an andesitic dike and although it was not confirmed by Howe, the Fortuna vein may continue to the northwest onto Medinah's ground, on the other side of the dike. SOUNDS LIKE MEDINAH MAY OWN A GOOD CHUNK OF THE FORTUNA DE LAMPA VEIN AFTER ALL. M.)"Although this type of vein mineralizaton could make an interesting exploration target for Medinah, the average grade of the mineralization returned from the initial sampling phases would have to remain consistently above 20 or 30 grams gold/tone across vein widths of no less than say, 0.5 to 1.0 metres for Medinah to justify continuing to explore for this type of mineralization. Areas of closely spaced or intersecting vein trends would be prime areas to target initially." I HAVE NEVER BEEN OVERLY EXCITED BY THE EPITHERMAL-VEIN DEPOSITS AT LIPANGUE-IT SEEMS NEITHER IS HOWE. N.) .."geophysics:-a magnetic survey should be completed over the entire gridded area(approximately 67 line kilometres) therfore generating new drill targets and a model to apply for regional exploration purposes; interpretation of the data to look for zones of structural dilation created by the intersection of major structural trends or post mineral faults which could control the location of additional breccia style mineralization, and signatures typical of porphyry style minerlization which could be associated with the breccia at depth; a preliminary interpretation of the magnetics should be completed prior to starting the IP survey, so that additional IP/resistivity lines can be planned over any resulting magnetic anomalies. It would be advantageous to incorporate the magnetic results in the structural interpretation." SOUNDS LIKE HOWE WANTS TO EXPLORE THE WHOLE MOUNTAIN-I THINK HOWE EXPECTS TO BE BUSY EXPLORING LIPANGUE FOR THE NEXT 20 YEARS! :) OVERALL, SOUNDS LIKE HOWE IS IMPRESSED WITH LDM/LIPANGUE-JUST ANOTHER INDEPENDENT VOICE GIVING THEIR APPROVAL OF THE PROPERTY. CHEERS.
