Matthew Russell, President of Azteca Gold Corp. ("Azteca" or the
"Company") (TSX VENTURE: AZG) announces the publication to its
website of an independent analysis that summarizes the significant
findings of a recent down-hole gravity geophysics survey of hole
DDH-005A/B (note: DDH-005B begins at 3900 FT in hole DDH-005A) from
600 m to 2850 m and the upper portion of DDH-006 from 150 m to 450
m at its 50% owned Two Mile Project. Richard Nanna, the Company's
QP, has reviewed and has accepted as technically accurate the
Scintrex gravilog data, with all relevant correction factors
applied, as well as the report dated November 16, 2009 (the
"Report") by Geoaviation LLC, an arms-length geophysical consulting
company located in Chandler, Arizona, which summarizes the forward
modeling conducted on this Scintrex down-hole gravity data. Down
hole geophysical surveys are done in an effort to identify, through
the differences in gravity measurements, layers or masses of
mineralized material around or immediately below the drill hole.
Significant Gravity Anomalies Found
Geoaviation LLC documents several significant gravity anomalies
in hole DDH-005B: (1) 1312-1374 meters (light blue body in figures
4 & 5), (2) 2170-2800 meters (dark blue stratigraphic layer or
band in figures 3,6,7, & 8) including "higher density
incursions" such as (3) red body in figures 6, 7, & 8 and (4)
green body in figures 7 & 8 between 2550-2660 meters.
Anomaly (1): After reviewing the core in the region of this
anomaly, Mr.Nanna has concurred with management's plan to assay a
previously un-assayed portion of the core from roughly 4300 FT to
4500 FT which includes this interval from 1312-1374 meters. The
author of the Report suspects a localized body denser than the
immediately adjacent strata above and below it. Mr. Nanna stressed,
"Further drilling, assaying, and analysis will be required to
confirm what the excess mass consists of."
Anomaly (2): The author of the Report suspects a much broader
layer of strata from 2170-2800 meters that is consistently elevated
above the adjacent rock densities. The author further documents
specific anomalies within this layer which may represent offset
"excess masses" such as that given by the red body in figures 6,7,
& 8. A significantly larger anomaly was documented by the
author as the green body in figures 7 & 8 between 2550-2660
meters. After reviewing the core in the region of this anomaly, Mr.
Nanna has concurred with management's plan to assay a previously
un-assayed portion of the core from roughly 8300 FT to 8700 FT
which includes this interval from 2550-2660 meters. Mr. Nanna
stressed again, "Further assaying, analysis, and drilling will be
required to confirm what the excess mass consists of."
Assay Plan
Based upon the geophysics conducted to date on the Two Mile
Project, Mr. Nanna has recommended that the Company conduct an
extensive program of assaying of drill core for the purpose of
analyzing the various anomalies to the extent possible before new
additional drilling is begun. The Company has already begun this
program, and as financing permits plans to assay for target
minerals such as Pb, Zn, Ag, Cu, and Au as well as for carbonate
ion CO3 and relevant carbonate anions Ca, Fe, and Mg in the
following sections:
Anomaly (1): Initially in DDH-005B and later in DDH-005A from
4300 FT to 4500 FT with enlargement of the interval if economically
significant assays are confirmed. Mr. Nanna may recommend assaying
a similar interval in DDH-006 prior to a gravilog re-survey of
DDH-006 based on a visual inspection of the core in this
interval.
Anomaly (2): Initially in DDH-005B and later in DDH-005A from
8300 FT to 8700 FT with enlargement of the interval if economically
significant assays are confirmed. Mr. Nanna may recommend assaying
a similar interval in DDH-006 prior to a gravilog re-survey in
DDH-006 based on a visual inspection of the core in this
interval.
Anomaly (A&B): Mr. Nanna has recommended that the Company
re-visit the IP (induced polarization) geophysical anomalies upon
which the 2007 core drilling was conducted. Although Mr. Nanna has
found nothing economically material to report in the assays of
these 4 core holes (DDH-001, DDH-001A (DDH-001A is the top 1595 FT
of DDH-005A), DDH-002, and DDH-003), he recommends that the Company
conduct enough assaying of the upper portion of holes DDH-005 and
DDH-006 to attempt to tie the IP anomalies together with the
gravilog surveys of DDH-005A/B and DDH-006.
Anomaly A: To this end, Mr. Nanna has identified an interval in
DDH-005A from approximately 1600 FT to 2000 FT to assay as well as
DDH-006 from approximately 1500 FT to 2000 FT. Mr Nanna has
concurred with management that Figure 1 of the Report suggests a
significantly higher rock density above 600 meters. This target
interval coincides with the higher intensity of the IP anomaly of
line A of the Quantec geophysics conducted in 2006 and which IP
line is in close proximity of both DDH-005 and DDH-006 collars.
Anomaly B: Also to this end, Mr. Nanna has recommended the
Company channel sample any adits or exploration drifts such as the
Harlow exploration drift and any other nearby exploration drifts
which may be used for further near-surface gravity surveys which
can be tied into the down-hole gravity surveys. The Harlow is an
approximately 300 FT generally WWN striking exploration drift
located approximately 1500 FT north of the collar of DDH-006.
DDH-006B Geophysics Plan
The Company is in the process of scheduling with Scintrex a
near-term re-logging of the gravity survey conducted on DDH-006.
Logging above 600 meters in hole DDH-005 is also being looked at.
As mentioned in a recent press release, the Company is looking at
conducting a surface gravity survey and near surface gravity survey
in nearby exploration adits and drifts such as the Harlow.
Further Testing Suggested by QP
The author of the Report has recommended and Mr. Nanna has
requested, financing permitting, that the Company perform a
gamma-gamma survey on the two core holes DDH-005 and DDH-006 in
order to correlate actual density of the core at the bore-hole with
the densities found by the gravilog survey in the vicinity of the
bore-hole. The Company is looking into how this gamma-gamma survey
may be conducted in conjunction with the gravilog re-survey of
DDH-006B.
Drilling Plan
The Company plans to finish the re-logging of DDH-006 and an
accompanying report prior to making a decision on future drilling
plans. Currently the Company is working with its drilling
contractor to put together cost estimates on drilling shallower
targets as identified by the Report as given above as well as the
deeper targets, including continuing to greater depth of DDH-005B
and DDH-006B.
Summary
The Company has until recently been focused primarily on massive
sulfide targets at depth. Recent gravity geophysical results, as
well as a re-assessment of previous IP geophysics work, has given
the Company cause for a second focus on carbonate hosted
disseminated mineralization, especially as it may apply to
potential silver mineralization and to potential mineralization
much higher in the drill holes (closer to surface) than previously
considered. "Our reasoning behind using gravity geophysical surveys
in our deep core holes was to detect differences in density in the
rocks in the area of the holes, then relating those changes to
changes in density expected by sulfide mineralization and
alteration." says Matt Russell, President of Azteca, "We are very
pleased to see gravity anomalies that may be used to target further
exploration drilling."
