MEXIVADA TO BEGIN DRILLING AT LA REPUBLICA IN MEXICO: PROJECTS
UPDATE
=======================================================================
La Republica Silver-Gold-Zinc-Lead Project, Yécora District, Chihuahua,
Mexico: Mexivada Mining Corp. has mobilized a core drilling rig to
its La Republica property, to conduct a 2000 metre Phase 1 drilling
program. Aerial photography of the project area was flown for the
company by Eagle Mapping, which is constructing a new topographic map
of the La Republica mine area, using new survey data. Mexivada has been
modeling the La Republica mine workings, which are reported to have
yielded a historical mine production of more than 5,000,000 ounces of
very high grade silver to 1908. The presence of visible gold in the
mine suggests the possible presence of a hidden, early gold-quartz vein
system in addition to the main silver-rich veins. The average reported
mine head grade at La Republica was over 100 ounces per ton silver.
La Republica was mined first between 1906 through 1908, with later,
lesser production to 1910 or 1911, when the Mexican Revolution erupted.
It was selectively mined down through a decline shaft down to the 50.6
metre level and possibly down to the 91.5 metre level. A 99 metre deep
vertical production shaft was sunk and a crosscut was driven on the 81
metre level to or toward the decline shaft, and these mine workings may
be useable in a new mining operation on site. Channel sampling on the
91.5 metre level was reported in May 1908 to have assayed 5,990 grams
per tonne ("g/t") silver across a 3.65 metre true vein width, along a
drift length of 33.8 metres. This "Main Stope" zone never has been
drill tested, and Mexivada's first two drillholes will explore its
downdip projection, below the 91.5 metre level, on each side of the
decline shaft. Other holes will test the southern extensions of the
Main Stope zone and the northern "Polverine" zone, where Mexivada's
channel sample of the La Republica vein across a 2 metre true width
assayed 1,230 g/t silver, 0.88% zinc, 0.31% lead, and 0.2 g/t gold.
Gold Junction Drilling Project, Round Mountain District, Nevada:
Mexivada completed a 3-hole Phase 1 reverse-circulation drilling
program at its Gold Junction, Nevada property. Locally anomalous gold
values, of up to 39 parts per billion gold over a 1.5 metre drilling
sample interval, were found in both holes of the "OP Target" zone.
These assays have led to definition of a new Gold Hill-type,
westerly-trending gold target, which heretofore was unknown by the
company. This new target zone will be shown on a cross section to be
posted to the Mexivada website at www.mexivada.com The third drillhole,
situated to the east of the "OP Target" on a different fault target,
also yielded several similarly anomalous gold values, but have not led
to definition of a viable gold exploration target there. Mexivada is
formulating a program to test the newly discovered target zone.
Moly Dome, Nevada, Molybdenum-Copper-Gold Project: Mexivada has
received approval of its Notice of Intent to Conduct Exploration
drilling at its 100% owned Moly Dome property with the U.S. Bureau of
Land Management. The company is evaluating core drilling contractors,
with drilling expected to commence in October, 2007.
Mexivada's geophysical contractor completed a Self-Potential survey in
the Moly Dome porphyry molybdenum-copper-gold target area. The SP
survey data generated were consistent with the presence of a
mineralized (sulfide-bearing) "porphyry" target system present at
shallow depths at Moly Dome. An induced polarization ("IP") survey was
re-started, but again had to be temporarily suspended due to extreme
fire hazard weather conditions at Moly Dome. The IP survey is scheduled
for resumption on October 1st by Durango Geophysical Operations.
Mayoko Greenstone Belt Gold and Diamonds Project, ROC Republic of
Congo:
Mexivada's ROC subsidiary, Compagnie Minière du Chaillu ("M2C"), is
continuing its steady program of geologic and geochemical exploration
for gold and diamonds near Mayoko, in its exclusive Malambani
concessions area.
Gold: Gold is present at Mayoko in two, 20 plus kilometre long,
sub-parallel mineral belts. M2C found a new gold bearing area in August
at Lesseseti in the southern belt, by tracing gold placers upstream to
their source, where gold-quartz veining is present across substantial
widths in quartzite and biotite gneiss. Mexivada is presently sampling
this area and will send the channel samples off for rush fire assaying
at ISO-approved labs in Johannesburg. Seven areas with gold in banded
iron formations have been found by M2C along the northern mineral belt
at Mayoko. Work on these target areas will continue in September, with
the goal of defining drill targets for testing in 2008. Several placer
gold targets have also been defined by M2C.
Diamonds: M2C has dropped its southerly "Nzambi" Permis de Recherche
for diamonds, to focus on the higher potential gold and diamond areas
further northward at Bikélélé, Carrefour, and Malambani. M2C recently
discovered 11 small alluvial macrodiamonds through geochemical
sampling, each less than 2.5 millimetres in diameter, at its Bikelele
and Carrefour target areas in M2C's Bitsandou exclusive permit area.
M2C will conduct follow-up investigations in this area during September
and October, looking for primary diamondiferous kimberlite host rocks.
M2C presently is exploring a diamond target on the Malambani concession
at Bilala where the Avoine Company found a 22 millimetre colorless
octahedral gem diamond crystal after World War II. An Avoine map shows
diamonds having been found in east-northeast trending creeks near
Bilala, possibly indicating trend-parallel diamondiferous dikes or pipe
sources for the Bilala diamonds. M2C's initial wash sampling recovered
the following diamond indicator minerals: ilmenite, chromite, and a
possible pyrope garnet. M2C now is studying an 800 by 200 metre
gravel-covered area at Bilala using bulk sample testing. Test samples
will be sent to Mineral Services Laboratory in Capetown for
verification of mineral identities.
Mexivada Cash Resources: All of Mexivada's cash resources are being
held in cash and Guaranteed Investment Certificates at a major Canadian
bank. Mexivada has no exposure to asset-backed commercial paper
("ABCP") investments that could be subject to creditor default.
