NEWS
RELEASE
MEXIVADA TO BEGIN
DRILLING AT LA REPUBLICA IN MEXICO: PROJECTS
UPDATE
La Republica Silver-Gold-Zinc-Lead
Project, Y�cora 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
Mini�re 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
Bik�l�l�, 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.
