These new assay results include the following programs and intervals:
- The Harlow Silver Vein Zone program, comprised of samples from surface, samples from multiple-adits and historical drill holes (see results 1,2,3,4a,& 4b below) Samples ranged from approximately 2.5 kilograms to approximately 7.0 kilograms and averaged approximately 4.5 kilograms. A 250 gram pulp from each sample was used for analysis.
- Interval 1500-2000 FT in diamond drill hole DDH-005A (see results 5 below)
- Interval 1500-2000 FT in diamond drill hole DDH-006 (see results 5 below)
Matt Russell explains, "These assay programs were the result of analysis that attempted to make full use of the extensive drill core data and various geophysical and geological data sets generated on the Project to date. Our exploration goal has been to identify significant silver dominant mineralization, which in the Silver Valley would typically include lead, copper and zinc credits."
Harlow Silver Vein Zone
The Company channel-sampled 4 silver veins lying parallel with the NE dipping Burke meta-sediments in two surface cuts and within two historical exploration adits (short tunnels into the hillsides). The samples were taken from channels cutting across the face of the exposed vein, perpendicular to strike. Assay results are presented below, along with down-dip historical drill hole intercepts. A conceptual depiction of these silver veins within an approximate 225 FT wide drill target zone called the Harlow Vein Zone can be found in Figure 3 of a series of 4 figures accompanying this press release on www.sedar.com and also found on the Company's website under the title and date of this press release. The Company has bounded this zone by the elevations of the Harlow Portal and the Harlow Cut-II, which are approximately 225 FT apart stratigraphically. Further discussion of this Harlow Silver Vein drill target zone can be found below under Near Surface Silver Target Exploration Plan below.

Channel samples were taken at various heights in the NE wall of the Harlow adit, and the Station locations represent FT into the adit from the Harlow Portal. The Harlow Silver Vein dips shallowly to the NE and appears at all station locations to have continuity into the SW adit wall with similar vein widths as sampled in the NE wall. The vein strikes approximately WWN as shown in Figure 4. (2) Assays are from historical diamond drill hole RA-9 (by others) which was found by the Company in the top of the adit at approximately 191 FT from the Harlow Portal. From projected angle of drill hole, the interval can be assumed to be a true width. We placed this interval in this chart to show it in context with the channel samples around it. 2.

DH-60 intercept is 264-267 FT and DH-65 is 67.1-67.9 FT. Historical data was presented in oz/ton. One troy ounce contains 31.1035 grams, and a short ton weighs 2000 lbs. while a metric tonne weighs 2204.6 lbs.
Although the Company believes that this historical data can generally be relied upon, readers are cautioned that neither the Company nor its QP has done any independent work to confirm the data.

5. New Silver Discovery within Assay Interval 1500-2000 FT in 005A and 006
The Company is pleased to present the following significant silver and base metal assays, including this notable result:
616 g/tonne Silver, 1.37% Lead, and 0.61% Copper over 2.0 FT.
Richard Nanna explains, "The mineralization is within an enriched carbonate zone which may explain the higher gravity readings above 600m in the Scintrex gravity survey. The mineralization in both holes appears to be in similar stratigraphic location within the IP anomaly that Quantec geophysics outlined in 2006, and upon which the Company's original 2007 Two Mile drill program targeting was based." Holes DDH-005A and DDH-006 are approximately 1 km apart.

Gravity Anomaly (2): Follow-Up to DDH-005A Massive Sulfides Discovery
In addition to the two at-surface and near-surface discoveries of silver mineralization described above, the Company wishes to emphasize the importance of further investigating the deeper silver and base metal intercept discovered at approximately 7900 FT in hole DDH-005A as disclosed in the January 13, 2009 press release:
- 15.5 FT of 40.0% Zn, 7.4% Pb, and 140.7 g/tonne Ag... which is included within the larger interval,
- 37.0 FT of 18.0% Zn, 3.6% Pb, and 61.9 g/tonne Ag
Richard Nanna has recommended further assaying of various un-assayed intervals in DDH-005A, DDH-005B and DDH-006 for the purpose of indentifying possible extensions of the mineralization discovered by the above intercept. "Such extensions, if they are found to be anomalous in silver or base metals, would be significant because of the large distances between drill holes at these depths," said Mr. Nanna.
As a next step, the Company will, as financing permits, assay portions of the intervals 7100-9200 FT in each of the three holes, which correspond to Gravity Anomaly (2) at 2170-2800 meters disclosed in the November 19th, 2009 press release.
Gravity Anomaly (1)
Also per Mr. Nanna's recommendation, the Company has sampled and will assay the approximate interval 4250-4500 FT in holes DDH-005A and DDH-006. The purpose for this assay project is to identify mineralized intervals that may be associated with Gravity Anomaly (1) between 1312-1374 meters as disclosed in the November 19th, 2009 press release.
Near-Surface Silver Target Exploration Plan
Figures 3 and 4 identify elevation and plan locations respectively for a proposed fan of drill holes to be accomplished from drill pads DDH-007 and DDH-008. Silver targets include the Harlow Silver Vein Zone as well as the 2006 IP Geophysics Target Zone which begins approximately 1500 FT below the Harlow Silver Vein Zone and is expected, per the IP geophysics, to be parallel to the Burke Meta-sedimentary layers. The Company emphasizes that DDH-007 and DDH-008 may also be used to drill test deeper targets should Gravity Anomaly (1) and (2) assay results support these targets. Drill stations were chosen on existing roads to facilitate USFS permitting and to limit environmental impact by the Project.
Silver and Base Metal Production in the Burke Meta-sediments
The Burke meta-sediments in the Silver Valley of Idaho host many historical silver mines, such as the prolific Hercules Silver Mine. By 1970, 23 million tons of ore had been produced out of the Valley's Burke hosted mines, at an average of 5.6 oz/ton Ag, 8.7% Pb, and 2.6% Zn.
The Bunker Hill Mine, by comparison, had produced 27,000,000 tons of ore by 1970 within the Revett-St. Regis meta-sediments (which overlie the Burke) at an average of 3.7 oz/ton Ag, 8.0% Pb, and 3.7% Zn. Historical numbers are from E. N. Pennabaker, 1971.

Summary
"Azteca Gold has until recently been focused primarily on massive sulfide targets at depth," said Mr. Russell. "Recent gravity geophysical results, as well as a re-assessment of previous IP geophysics work, have given the Company cause for a second focus on multiple zones of potential mineralization much closer to and at-surface. These zones initially appear to be carbonate hosted, and our ongoing assay programs will allow us to further define our drilling programs beyond the near-surface silver targets for 2010."
Diamond drill core and channel samples were processed per the Company's chain of custody controlled by Azteca personnel who transferred the samples directly to American Analytical Labs, located at Osburn, Idaho, an independent and fully accredited lab. The assay lab has provided assay results to only those within Azteca's control pursuant to the list provided to them by Matt Russell. Material assay results are considered preliminary by the Company until check assays are received.
Assay methods include fire assay for Ag and Au. ICP (inter-coupled plasma) was used for lead, zinc, and copper. Carbonate (CO3) was titrated.
