First mined by the Spaniards in the 17th Century, with the major production period from 1870 to 1900, this area has potential high-grade gold deposits which could not be mined with the crude methods of the day.
This property is located near two major sites:
Located in the Barranca section of Chihuahua, the 1,514 hectare Guazapares property is 100% owned by Mexoro Minerals (subject to a 2.5% NSR) and has the infrastructure in place to support possible mining operations. Accessible year-round by air, rail and land, the area has power, water, and access to trained miners.
From 1870 to 1900, four silver pan amalgamation mills operated in the area. However, despite the gold deposits, the early mills could only recover the oxidized portions of the very fine gold which occurred along cleavage planes in the pyrite. As a result, the substantial unoxidized, sulphide-bearing material was usually left in the mines as pillars. In 1905, a U.S. company purchased the mine, but the market panic of 1907 and the revolution in 1912 put an end to those efforts.
In 2002, just 30 kilometers to the northeast, Kimber Resources began exploration of the Monterde site, identifying old deposits of at least 3 million ounces of gold. In 2003, Bolnisi Gold commenced exploration of the Palmajero mine, with confirmed deposits of 3 million ounces of gold.
The Guazapares property sits at the interphase of two volcanic groups that comprise the bulk of the Sierra Madre Occidental.
Mexoro Minerals Ltd. is pleased to announce that it has intersected gold and silver mineralization from drilling at its Guazapares project located in the Guazapares Mining District, Chihuahua, Mexico. The first drilling program in the Guazapares project has been completed with nineteen drill holes totaling 2,670 meters. The new drilling results are from thirteen recently completed holes drilled at the San Francisco Este, San Francisco Centro and El Cantilito, three of the main targets identified in the project. All drill holes in the San Francisco Centro and El Cantilito intersected long intervals of gold and silver mineralization. Drill results can be viewed below.
The San Francisco Este target is characterized by mineralized veins/breccias, quartz veins stock worked zones. The mineralized and altered zone on this target trends predominantly northwest. Drill holes GU-04 to GU-07 and GU-17 to GU-18 were designed to test the silver (± gold) mineralization identified on surface. GU-04 intersected 9.55 meters with 2.17 g/t Au Eq from surface down to 10 meters depth. The drill hole GU-08 encountered a mineralized interval of 5.20 meters with 1.68 g/t Au Eq. These intervals complement previously announce results for the surface sampling where we reported silver values up to 2,160 g/t Ag. Drill holes GU-05, GU-06 and GU-07 reported only gold and silver anomalies. Assay results from GU-17 and GU-18 are still pending. Results from the mineral zone at San Francisco Este are summarized below:

The San Francisco Centro target is characterized by quartz veins, veins/breccias and quartz veins stock worked areas exhibiting multiple pulses of hydrothermal activity. Mineralization in San Francisco Centro tends to cluster in ore-shoots developed primarily in the intersection of main structures. Drill holes GU-08 to GU-13 were planned to test the east-west mineralized structure identified during the mapping and sampling process in the central part of the concessions. All drill holes intersected mineralization from surface down to 100 meters depth. The drill hole GU-10 intersected 13.75 meters with 2.75 g/t AU Eq. and 22.98 meters with 2.80 g/t Au Eq. from 8.15 meters down to 85 meters depth. Drill hole GU-13 intercepted 9.0 meters with 3.63 g/t Au Eq. and 4.50 meters with 1.56 g/t Au Eq.

El Cantilito is a mineralized zone produced mainly along northeast vein-structures where mineralization tends to cluster in mineralized-shoots and mineralized stock works developed in structural jogs and/mineral intersection of main structures. Drill holes GU-14 to GU-16 and GU-19 were designed to test the outcropping mineralized structures. Drill holes GU-15 and GU-16 were collared in the west margin of the known limit of the mineralized structure and have opened up the exploration further west along El Cantilito structures. Drill hole GU-15 was stopped at 168 meters depth still in mineralization intersected 17.06 meters with 1.26 g/t Au Eq. including 1.30 meters with 6.10 g/t Au Eq. Drill hole GU-16 intercepted 18.92 meters with 4.33 g/t Au Eq. including 7.74 meters with 9.10 g/t Au Eq. The assay results from GU-19 are still pending.

The mineralization systems encountered in the Guazapares project are essentially of two types: a silver-dominated system at San Francisco Este, San Francisco Centro, and El Cantilito which is exhibiting localized areas of above-average grade gold mineralization; whereas at San Antonio, the system is dominated by gold mineralization. Surface mapping and drilling results are suggesting that the high-grade mineralization tends to cluster at certain areas along the mineralized veins with intervening areas of low-grade mineralization. The cluster of high-grade mineralization is suggesting the development of mineralized-shoots as evidenced by the intercepts from drill holes GU-04 and from GU-08 to GU-16.
The present drilling results are providing the evidence to highlight the potential of several areas in the Guazapares project.
Mexoro is pleased to announce the latest results from the diamond drill program at the Guazapares project in the Temoris District, Chihuahua, Mexico.
The Guazapares project is dominated by flows and tuffs of rhyolitic-dacitic and in lesser amount of andesitic composition that may correspond to the upper portion of the Lower Volcanic series of the Sierra Madre Occidental Volcanic Complex. Mineralization seems to be closely associated to a rhyolitic-dacitic intrusive body domal in shape and consisting of a series of sub-vertical, brecciated, quartz-rich zones that outcrop within an area of 4 km2 and have been trace for approximately 2 km. There are three main drilling targets identified inside project area known as San Antonio, San Francisco and El Cantilito.
A 3,000 meters drilling program consisting of 27 diamond holes have been programmed to evaluate the Guazapares project. The drilling program has been designed to:
The holes GU-01, GU-02, and GU-03 have been focused on extending zones of above-average grade mineralization encountered in the San Antonio adit. To date we have received assay results for the three drill holes.
The following are the assay results for these drillholes are reported below.

Diamond drilling of the San Antonio system encountered mineralization in the three drillholes. The highest grades occurred within vein-breccias, quartz veins and quartz stockwork veins exhibiting multiple pulses of hydrothermal activity.
Holes GU-01, GU-02, and GU-03 confirm the emergence at San Antonio of one of the high-grade mineralized-shoot identified in the San Antonio adit (press release May 22, 2007). These three drillholes provide also the evidence that main mineralization tends to cluster as mineralized-shoots controlled by mainly by the intersection of northwest, east-west, and northeast structures.
Analysis of the mineralization and alteration assemblages, structural setting and geochemistry of the San Antonio target area indicates that the above-average gold values tend to cluster in two main mineralization styles:
Drilling continues to explore intense altered and mineralized areas and all mineralized-shoots identified on the San Francisco and El Cantilito areas.

Exploration Activities Update to 22nd May 2007
Mexoro Minerals Ltd is pleased to announce that it has received trench and channel sample results from the Guazapares project, Chihuahua, Mexico. These sample assay results are derived from the initial mapping and sampling program on two of the four targets identified at the Guazapares project: San Antonio and San Francisco targets.
The Guazapares project consist of a series of sub-vertical, brecciated, quartz-rich zones that outcrops within an area of approximately 4km2 and has a strike length of over 2 km. Mineralization is controlled by north-northwest, west-northwest and east-northeast striking faults-veins and fault-breccias separating rhyiolites and dacite-andesite tuffs. This mineralization has been observed for over 2 kilometers suggesting an attractive potential further northwest from the San Francisco and San Antonio targets.
Better mineralized shoots appear to occur where west-northwest/north-northwest structures intersection occur in the main fault-vein and fault-breccia zones as shown in figures 1 and 2 below at the end of the project description.
The San Antonio target area where most of the early mining was focused is characterized by two main mineralized vein domains trending northwest and west-northwest and mineralization comprises and area of approximately 500 x 300 meters.
Samples reported here are mostly composites made up of 2 meters average. Results for the San Antonio adit (figure 1) include:
| Sample ID | Au (g/t) | Ag (g/t) | Sample ID | Au (g/t) | Ag (g/t) |

The San Francisco target area is characterized by veins/breccias and quartz veins stockwork zones covering an area of approximately 500 x 700 meters. The exploration program on this area has outlined the main vein zone and several parallel veins/breccias zones. The mineralized zone trends predominantly northwest developing above-average grade gold-silver concentration where west, north-west, and northeast structures intersections occur.
Samples reported from the San Francisco target are from trenches along a west-northwest structure (figure 2). Assay results from San Francisco include:
| Sample ID | Au (g/t) | Ag (g/t) |
| 4601 | 11.4 | 585 |
| 4599 | 3.84 | 505 |

Mexoro's exploration team continues with the current exploration program and to access the recent and historical data from the Guazapares project. Given the good condition of the adits, channel and trench sample results, Mexoro intend to start a drilling program targeting the known mineralization at depth and along strike as well as near-surface mineralization. The drilling program is expected to commence late May-early June depending of equipment availability.
Exploration Activities Update to 23th April 2007
Mexoro Minerals Ltd has completed the first stage of its exploration program at the Guazapares Project. An integrated program of geological mapping, surface sampling and mapping and sampling of accessible underground workings was the initial phase of this ongoing exploration program.
The present report describes the salient geological features on the Guazapares project based mainly on the field observations gathered by the Mexoro's geological team during recent reconnaissance programs.
 Figure 1 is showing the Guazapares Project geology and mineralized areas. |
 Figure 2 is showing the structural setting and related mineralized areas at Guazapares project. |
The geology at Guazapares is dominated by flows and tuffs of andesitic and rhyolitic composition that may correspond to the upper portions of the Lower Volcanic Series of the Sierra Madre Occidental Volcanic Complex. These volcanic rocks, which host most of the mineralization in the Guazapares district, are unconformably overlain by a thick, predominantly rhyolitic ignimbrite sequence. Extensional faulting formed predominately north-northwest striking structures with subordinate west-northwest and minor north-northeast faults have been identified throughout the project area.
Geological mapping and sampling over an area of 4 km² has outlined numerous mineralized areas within the project area (figure 1).
The Guazapares project consist of a series of sub-vertical, brecciated, quartz-rich zones that outcrop within an area of approximately 4 km² and have an strike length of over 2 km. The mineralized areas and identified drilling targets include four main zones: San Antonio, San Francisco, El Cantilito and Montaña de Oro. The mineralization is characterized by silver-gold low-sulphidation veins, locally overprinted by high-level high-grade gold-silver quartz veins. The mineralized areas and veins are structurally-controlled by north-northwest striking faults and west-northwest trending faults that have favored the development of high-grade ore shoots as shown on figure 2.
Mineralization style at Guazapares is characterized by gold-silver veins and vein-breccias occurring within and/or at the intersection of numerous north-northwest structures (San Francisco and San Antonio Fault Systems) and west-northwest structures (San Antonio and El Cantilito Fault Systems).
On the basis the field evidence all four mineralized areas have been considered to be prospective in which three of them San Francisco, San Antonio and El Cantilito have been followed up with initial geological mapping and sampling.
San Francisco Area is characterized by mineralized quartz veins, vein/breccias and quartz veins stockworked zones covering an area of approximately 500 x 700 m. The mineralized zone trends predominantly northwest developing high-grade mineral concentration within the intersection of the west, northwest and northeast trending faults as shown in figure 2. The San Antonio area includes mainly stockwork mineralization and silicification, exhibiting small and localized areas of vuggy quartz within the volcanic rocks. Detailed rock chip sampling along these mineralized zones has returned frequent high silver values (2160 g/t Ag), where gold values normally varying from 1.17 to 2.28 g/t Au.
San Antonio Area. Early mining was focused mainly on the San Antonio vein domain where high-grade gold mineralization (42.6 g/t Au and up to 1100 g/t Ag) is present in underground workings. Two main mineralized veins domain trending northwest and west-northwest have been identified within this targets area. Mineralization is found over an area of 500 x 300m and consists of quartz veins and quartz stockworked veins exhibiting multiple pulses of hydrothermal activity. Assay results from rock chip samples have returned gold values roughly from trace to 8.76 g/t Au.
El Cantilito Area is a mineralized zone produced mainly along west and northeast trending structures where high concentration of gold are known, varying from 1.86 to 8.39 g/t Au and some high grade silver values of 656 g/t Ag. El Cantilito is characterized by quartz veins, quartz stockwork mineralization and silicification developed in approximately 500 x 350 m area within the hosting volcanic rocks.
Montaña de Oro Area is a newly identified target to the north of the Guazapares project. Montaña de Oro is characterized by mineralized structures trending north-northeast, where development of ore-shoots containing gold values of (5.39, 7.22, 1.75, 19.7 and 2.5 g/t Au). Ongoing mapping and sampling indicate potential for a large system; however, additional field work needs to be conducted to confirm results.
Most of the Mexoro's exploration efforts have been concentrated on the San Antonio and San Francisco vein domains; but, the vein and breccias textures, structures, alteration and metal association suggest that mineralization areas in the Guazapares project are of low-sulphidation style. These structural and mineralized systems are open in both directions north and south. Detailed field work will continue in all identified targets in parallel with the road access and drilling platform on selected drilling locations.
