VANCOUVER, Sept. 5 /CNW/ -
La Republica Silver-Gold-Zinc-Lead Project, Yécora District, Chihuahua,
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
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 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.
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
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.
