1 SUMMARY
1.1 INTRODUCTION
Silver Wolf Exploration Ltd. (Silver Wolf or the Company) is a mineral exploration and resource development company based in Vancouver, B.C., Canada. It is a public company trading on the TSX Venture Exchange (TSX-V: GRK). The Company has entered into an agreement with Avino Gold and Silver Mines Ltd. (Avino) to acquire 100% ownership in the Ana Maria Property and El Laberinto Property which is an exploration and resource development project located in northcentral México. Note that the subject of this Technical Report are the Ana Maria Properties and the acquisition also includes the El Laberinto Property. El Laberinto is not material to the Company and as such is not the subject of a Technical Report.
In 2020, Silver Wolf commissioned Garth Kirkham, P.Geo., Principal, Kirkham Geosystems Ltd., to prepare an NI43-101 Technical Report for the Ana Maria properties which are early stage, exploration properties. Ana Maria is a carbonate replacement (CRD) prospect.
1.2 ANA MARIA PROPERTY
The Ana Maria property is located 21 kilometres (km) northwest of the City of Gómez Palacio and the adjacent City of Torreón, and 1 km north of the town of Dinimita, in the municipality of Gómez Palacio, Durango, Mexico. The concessions are located in the Minitas mining district in the Guadalupe Victoria mining region. The property consists of 9 mining concessions encompassing 2,549.0 hectares (ha).
These projects are located in the North West-South East striking fold-thrust belt of the Sierra Madre Oriental within a west trending prong known as the Sierras Transversales or the MonterreyTorreón transverse system. It divides the Mesa Central, an elevated plateau to the South, from the eastern Mexican Basin and Range to the North.
The region hosts a number of carbonate replacement deposits (CRD´s) within Cretaceous limestones and dolomites. Mineralization is associated with large stocks, dykes or sills of granitoids ranging from diorites to quartz monzonites and rhyolites and inferred to be lower crustal in origin. Mineralization is present as skarns or massive sulphides and occurred during Mid-

Tertiary volcanism when the aforementioned intrusions were emplaced (Megaw et al., 1988). The deposits typically produce silver, lead, zinc and copper although some districts, such as Ojuela (~10 kilometres from Ana Maria Norte), are enriched in gold relative to typical CRD´s.
1.3 CONCLUSIONS AND RECOMMENDATIONS
Table 1.1 are potential risks and opportunities that may affect, hinder or otherwise impact exploration and development going forward.

1.4 RECOMMENDATIONS AND BUDGET
The following two phased work program is recommended for the Ana Maria Project. They may be performed in series or in parallel, depending on resources and circumstances.
Effective Date: February 3, 2021

It is recommended that Silver Wolf complete geological mapping, surface geochemical sampling, Terraspec sampling and geophysical surveys in addition to performing a Lidar survey. In addition, initial baseline environmental data acquisition and reporting should be initiated and is recommended along with continued ongoing implementation of an Ejido/community consultation plan.
The view is that this work would support core drilling in the future. The author recommends:
-
Surface mapping
-
Lidar survey
-
Airborne- and ground-geophysical surveys
-
Geochemical sampling
-
Surface sampling, mapping, and prospecting
Table 1.2 presents an ongoing exploration and development program for the Ana Maria property. The Phase 1 program recommends initial reconnaissance and data integration work along with performing a LIDAR and Terraspec survey. This phase will include data analysis and modelling to determine prospectively to test the validity of the CRD deposit model hypothesis. The Phase 2 program is contingent upon the results and relative success of the Phase 1 program which would then employ geochemical sampling and geophysical surveying techniques to assist in target identification and support the selection of drill targets to further advance the project.
Approximate expense items are listed with a description, where appropriate, and a total cost. The length of this program is approximately 24 months from inception through to completion of a status report. All costs are in $US.

4.4 PERMITTING
Mining and exploration rights in Mexico are controlled by the Federal Government. Prior to 2006, exploration and mining rights were assigned to private Mexican individuals and companies incorporated under Mexican laws—including those companies fully financed by foreign investment—by granting “exploration” and “exploitation” concessions; each type of concession had different validation periods and tax and assessment obligations.
In December 2005, the mining laws were reformed and simplified. All new concessions are known as “mining concessions”, and they are valid for a 50-years and renewable for an additional 50 years. And, at the time, all previously issued “exploration” and “exploitation” concessions were automatically converted to “mining concessions” without changing the effective date of the title.
The mining concessions are administered by the Dirección General de Minas (DGM), a subsecretariat of the Subsecretaría de Minería under the cabinet-level Secretaria de Economia. To maintain concessions in good legal standing, concession holders are obligated to pay semiannual tax payments and file annual documentation of exploration or development work on the concession (i.e., a minimum investment as provided in applicable Mexican mining legislation). Concession holders are also obligated to file production reports for statistical purposes. The semiannual tax and the minimum required investment both increase each year in accordance with rates published by the Mexican Government: the older the mining concession, the higher the annual tax and investment amount. When the concessions are in their 7th year (or greater) of issuance, the required investment reaches the maximum applicable amount, and when the concessions are in their 11th year (or greater) of issuance, the amount of annual taxes payable reaches the maximum applicable rate.

The current semi-annual taxes are $433,924 MXP (Mexican Pesos) or $21,696 USD and are paid up until June 30, 2021.
4.5 ENVIRONMENTAL AND SOCIO ECONOMIC
Surface access to the Ana Maria Properties is controlled by the local Ejidos (area of communal or Ejidos land). For the Ana Maria concessions the surface access to the concessions is controlled by the La Mina and Leon Guzman Ejidos (area of communal or Ejidos land) of La Mina and Leon Guzman. Agreements with individual Ejido landowners are negotiated as required to access the deeded lands.
As of this report the Ejido leaders have been contacted and the appropriate arrangements are being negotiated to allow for a surface rights access agreement to be finalized. Finalizing agreements with the respective Ejido may not occur which would pose a risk to exploration and development of the properties however, there are currently extensive mining operations in and near Ana Maria so it is reasonable to assume that agreements can be completed.
The author is not aware of any other significant factors or risks that may affect access, title, or the right or ability to perform the proposed work program on the property.
Avino employed a policy for the implementation of an effective community engagement program is fundamental to the successful environmental permitting of their mining projects. Silver Wolf is planning to adopt these programs going forward. As part of a comprehensive community engagement program, should be initiated as soon as possible. Consultation and the development of a working relationship with local communities typically involves the development of a series of agreements that lay the groundwork for conversations. These include memorandums of understanding, protocol agreements and community consultation/participation agreements.
Potential positive effects of the proposed project development include:
-
long-term, meaningful employment in mining operations and related positions (e.g., environmental monitors, service industry sector)
-
economic development and contract opportunities for local communities (existing and new businesses), and community infrastructure improvements.
For potential adverse effects of the proposed project are related to the development of infrastructure and facilities necessary to support exploration and mining activities. In the short term, the effect of exploration activities is minimal such as surface surveys and drilling.
There are no known environmental liabilities to which the property is subject.
Performing work in certain regions of Mexico may pose significant to moderate safety risks however, the areas in the vicinity of Torreon pose relatively low risk to safety. However, COVID-

6 HISTORY
6.1 INTRODUCTION
6.1.1 Ana Maria, La Recompensa, El Soldado Concessions
The historic exploration activities as listed below were performed by previous operators. The QP has not validated nor verified the information nor any underlying data however the information is considered reasonable and reliable.
Minimal documentation exists regarding the history and production at Ana Maria; however, historical reporting states that Ana Maria Norte which is also referred to La Lucha in the Mexican government source publications, was exploited for Iron (Fe) and Manganese (Mn). Production terminated in 1943 and it was estimated to have produced 12,000 tons of material and reserves of approximately 25,000 tons.
The Ana Maria or Ana Maria Norte property also encompasses the past producing La Zori goldiron mine and is located within a volcanic caldera. Mineralization at La Zori occurs within hematite - manganese breccias and veins near the contact of Cretaceous limestone-marble with a 10 km circular body of Tertiary coarse-grained granodiorite.
The historical estimates of production and reserves as stated above are for historical reference only and do not use the categories set out in NI 43-101. The estimates are deemed relevant from the perspective that mineralization is present on the property which may indicate the existence of other related mineral assemblages. The QP has not validated nor verified these historical estimates nor any underlying data as the information and data is not available. The QP has not done sufficient work to classify the estimates and the issuer is not treating the historical estimate as current. The source of the information is the Mexican Government website and USGS website and the original date of the sources are unknown. However, the information is relevant from the perspective that there is mineralization on the property which is also clear from the perspective of visual inspection of the properties and the presence of surface and underground workings. The issuer is not treating the historical resources as current mineral resources or mineral reserves.
Avino performed minimal work on these three concessions which consisted of geological staff visiting the site several times to perform reconnaissance.

7 GEOLOGICAL SETTING AND MINERALIZATION
7.1 REGIONAL GEOLOGY
7.1.1 Ana Maria, La Recompensa, El Soldado
The Ana Maria, La Recompensa, and El Soldado properties are located in the northwestsoutheast striking fold-thrust belt of the Sierra Madre Oriental (Figures 7-1 and 7-2) within a westtrending prong known as the Sierras Transversales or the Monterrey-Torreón transverse system. It divides the Mesa Central, an elevated plateau to the south, from the eastern Mexican Basin and Range to the north (Sedlock et al., 1993).

The region hosts a number of carbonate replacement deposits (CRDs) within Cretaceous limestones and dolomites. Mineralization is associated with large stocks, dykes, or sills of granitoids ranging from diorites to quartz monzonites and rhyolites and is understood to be lower crustal in origin. Mineralization is present as skarns or massive sulphides and occurred during Mid-Tertiary volcanism when the aforementioned intrusions were emplaced (Megaw et al., 1988 and references therein). The deposits typically produce silver (Ag), lead (Pb), zinc (Zn) and copper (Cu), but some districts, such as Ojuela (approximately 10 km from Ana Maria and La Zorra), are enriched in Au relative to typical CRDs.
Ana Maria and La Zorra lie between the Mapimi anticline to the northwest and the Marabunta anticline to the southeast (Figures 7-3 and 7-4). The former comprises a series of northwestsoutheast striking folds and the latter strikes north-south.

South of Ana Maria and north of La Recompensa, in the western limb of the Marabunta anticline, contact metamorphism between the El Sarnoso stock and limestones has created a marble body which hosts an actively quarry operation. At Ana Maria and La Zorra, skarn alteration is present near the contact with the granitoid, along with mineralization, and it is hosted in limestones of the Aurora Formation.
Paola, Jabalí and La Cross, collectively known as El Soldado, are all located farther south along the western limb of the Iglesia anticline in the Jurassic sediments of the La Gloria Formation. They are associated mostly with oxidation and lesser skarn alteration.
7.3 STRUCTURAL GEOLOGY
7.3.1 Ana Maria, La Recompensa, El Soldado
Regionally, the pre-Mesozoic rocks are hidden and poorly understood, but exposures farther north show strongly deformed rocks related to previous orogenic events (Anderson and Schmidt, 1983). Xenoliths suggest that part of the Sierra Madre Oriental is underlain by Proterozoic continental crust, while the oldest exposures are of metamorphosed sedimentary, volcanic, and igneous rocks interpreted to be part of a subduction complex. Axial planes strike northeast-southwest, and foliation generally dips to the southeast (Sedlock et al., 1993).
The Mesozoic units described in Figure 7-7 were deposited during the breakup of Pangea and the creation of the Gulf of Mexico. From the Triassic until the Early Jurassic, the Atlantic side of present-day Mexico was a passive margin and subduction was ongoing on the Pacific side (Gómez Nava and Olmos, 2012). The oldest rocks exposed locally were deposited during this timeframe and subsequently deformed: the weakly metamorphosed Nazas Formation (shown in Figure 7-7) was thought to have originated as a volcanic arc built on continental crust. Foliations and axial planes in the Nazas Formation strike northwest-southeast (Anderson et al., 1990). The tectonic event that deformed the Nazas Formation likely occurred in the Mid-Jurassic or earlier (Eguiluz de Antuñano et al., 2000), and it is not as well understood or studied as is Laramide shortening.

A major transgression followed in the Upper Jurassic with clastic sedimentation, later led by carbonate platforms, shales, and farther east, evaporites from Early- to Mid-Cretaceous when Laramide compression initiated (Gómez Nava and Olmos, 2012). The unconformity between the Nazas Formation and the overlying sedimentary rocks is an important one as Laramide deformation was thin-skinned with the Nazas unconformity, as well as other contacts with evaporites and shales, serving as décollements (Eguiluz de Antuñano et al., 2000; Smith, 1970). This isolated the deformation to post-Lower-Jurassic units, and, as a result, the deformation seen in the Nazas Formation does not seem to have been overprinted by Laramide tectonics (Anderson et al., 1990).
From the Late Cretaceous until the Neogene, Laramide northeast-southwest to east-northeast to west-southwest compression resulted in variable intensities of deformation based on proximity to the margins of the Sierra Madre fold and thrust belt. Ana Maria is situated near the centre and shows complex folding and faulting relative to the margins where folding is less intense and faulting is simpler (Megaw et al., 1988; Sedlock et al., 1993).
Laramide shortening switched to an east-northeast to west-southwest extension at about 30 Ma coincident with the intrusion of the El Sarnoso granitoid (Figure 7-8). The intrusives are postulated to be a result of the magmatic arc migrating westward around 32 to 25 Ma (Gómez Nava and Olmos, 2012). The emplacement of these granitoids is likely along deep-seated basement structures related to the breakup of Pangea. Basin and Range tectonics, associated with highangle normal faults, began at approximately 24 Ma and continues to the present. This resulted in intense erosion of the Cretaceous units and clastic deposition during the Cenozoic (Gómez Nava and Olmos, 2012; Sedlock et al., 1993 and references therein).

7.4 STRATIGRAPHIC SEQUENCE AND MAGMATIC HISTORY
7.4.1 Ana Maria, La Recompensa, El Soldado
The Paleozoic basement is hidden, and the oldest rocks regionally exposed are the metavolcanics of the Nazas Formation (Upper Triassic to Lower Jurassic) found approximately 20 km south and intercalated with sandstones and dacites. La Gloria Formation (Upper Jurassic) unconformably overlies the Nazas Formation with a base of polymictic conglomerates grading upward into intercalated calcareous sandstones, limestones, and dolomitic limestones. The formation is capped by siltstones and shales.
La Gloria Formation is generally overlain by La Casita and Taraises Formations which are not observed regionally, suggesting a significant unconformity. The La Casita and Taraises Formations, elsewhere, show a conformable upper contact with the base of the Cupido Formation, present in the area, and comprise granular to massive limestones with common stylolites and iron concretions. The unit is Early Cretaceous (Barremian-Aptian). Above the Cupido Formation, thinly bedded, laminated, muddy limestones are common with intercalations of foliated shales that together represent the La Peña Formation (Aptian). Conformably overlying La Peña is the Aurora Formation constituting a sequence of massive and granular limestones showing zones of dolomitization with fossils suggesting it is of Albian Age. A stratigraphic column is shown in Figure 7-7 for the area around Ana Maria. Although not present around Ana Maria and not displayed in the stratigraphic column, northwest near the village of Mapimí, the Aurora Formation is overlain

Ana Maria Project 2021 NI 43-101 Technical Report
==> picture [127 x 41] intentionally omitted <==
by the Indidura limestones and siltstones (Late Cretaceous). The contact between the two is often faulted.
The Mesozoic rocks are unconformably overlain by the Ahuichila Formation. This sequence of polymictic conglomerates (with clasts of limestone, sandstone, and chert) is of Tertiary age (Eocene-Oligocene). SW of Ana Maria, near the village of Vallecillos, the Ahuichila Formation is overlain by rhyolitic tuffs not seen around Ana Maria. Tertiary units are unconformably capped by Pleistocene conglomerates with clasts of limestone, sandstone, and siltstone that underly Holocene colluvium and alluvium.
The El Sarnoso granite complex is approximately 32±1 Ma (Early Oligocene) based on K-Ar dating and cuts the Mesozoic and Tertiary rocks as a series of stocks and dykes. (García Padilla and Román, 2008; García Padilla and Quezada, 2006; Gómez Nava and Olmos, 2012).

7.5 MINERALIZATION
7.5.1 Ana Maria
The mineralization occurs within skarn at the contact between the El Sarnoso stock and limestone of the Aurora formation. Primary minerals comprise psilomelane, pyrolusite, hematite and goethite. The hematite occurs as large red masses and is the principal source of iron from historic mining. Spectrographic analysis of the hematite reveals that As and Sb, very common among iron and Mn minerals at Ojuela, are lacking at Ana Maria. Magnetite is less common but has been exploited (Hoffman, 1968). Traces of galena, sphalerite and chalcopyrite occur sporadically. Gangue minerals are dominantly calcite and quartz (Gómez Nava, 2012).
Gold is associated with oxidized pods of pyrite along the boundary with the El Sarnoso stock (Peter Megaw, verbal comm.). Northwest, at the Mapimí deposits, gold is found in association with hematite, goethite, and Mn oxides but primarily in the upper oxidized portions of the deposit. Either the pyrite and/or the arsenopyrite is thought to be gold-bearing (Hoffman, 1968).
Ana Maria mineralization occurs as irregular lenses approximately 1.0 m long and 0.5 m wide that plunge 45° toward an azimuth of 205° (Gómez Nava, 2012).
7.5.1.1 La Zorra
Like Ana Maria, La Zorra lies at the contact between the Aurora formation and the El Sarnoso stock. Mineralization is situated in a breccia that has been strongly recrystallized with black calcite and aragonite with subangular crystals up to 50 cm in diameter. The breccia is associated with a fault striking north-northwest to south-southeast and dipping approximately 40° to the northeast that continues for at least 70 m. The depth of the structure is unknown. The dominant mineral is hematite, which acts as a cement between recrystallized clasts within the breccia. Mineralogical investigations have also identified arsenopyrite in the matrix of the breccia. Gangue minerals are calcite, aragonite, and quartz. Weak silicification and intense oxidation is also present. Iron grades up to 60% and gold grades up to 0.43 g/t have been demonstrated by analyses (García Padilla and Armenta Román, 2007).
7.5.1.2 La Recompensa
Veinlets of quartz, hematite, limonite, and Mn staining follow an irregular and brecciated structure striking north-northeast to south-southwest and dipping approximately 40° to the southeast. Ore minerals comprise pyrolusite, limonite, jarosite, galena, and sphalerite with gangue of quartz and calcite. Oxidation is common with hematite and limonite. Similar to Ana Maria and La Zorra, mineralization is hosted in the carbonates of the Aurora formation. Analyses show Mn percentages up to 7% (Gómez Nava, 2012).
7.5.1.3 Paola
Mineralization is present in pods plunging approximately 40° to the northeast. Mineralogy comprises hematite, goethite, jarosite, pyrolusite, sphalerite and galena. Gangue minerals include
Effective Date: February 3, 2021
7-16
Ana Maria Project 2021 NI 43-101 Technical Report
==> picture [127 x 41] intentionally omitted <==
quartz and fluorite, and oxidation (hematite and limonite) is common. The host rocks are calcareous sandstones of the La Gloria formation (Gómez Nava, 2012).
7.5.1.4 Jabalí
Mineralization is situated within an irregular breccia body striking north-northwest to southsoutheast and dipping approximately 35° to the southwest. The breccia is strongly fractured with jarosite, goethite, limonite, pyrolusite, sphalerite, galena, and malachite. Gangue is mostly calcite and quartz, and oxidation (hematite and limonite) is common. Like Paola, Jabalí is hosted within the La Gloria formation. Grab samples have returned lead values up to 4% and zinc up to 11% (Gómez Nava, 2012).
7.5.1.5 La Cross
La Cross consists of a series of small breccias, 1 to 3 m long and 0.3 to 0.5 m wide. Jarosite, goethite, pyrolusite, limonite, galena and sphalerite are the principal minerals. Gangue minerals are mostly calcite and quartz. Recrystallized calcite is observed along with oxidation (hematite and limonite). Host rocks are calcareous sandstones of the La Gloria formation. Channel sampling returned zinc values up to 3% and lead up to 2% (Gómez Nava, 2012).
7.5.1.6 La Cross 2
This mined-out mineralized structure is 16 m long, irregular in shape, with widths up to 8.0 m and a depth of 2.0 m. The structure strikes northwest to southeast and dips approximately 30° to the southwest. Jarosite, goethite, pyrolusite, limonite, sphalerite and galena comprise the primary minerals with gangue mostly of calcite and quartz. Oxidation is common (hematite and limonite). The structure is hosted by limestones of the La Gloria formation. Channel sampling returned assay values of up to 1.4% zinc (Gómez Nava, 2012).

8 DEPOSIT TYPES
8.1 ANA MARIA
Ana Maria, La Recompensa, and El Soldado have not been drilled or extensively mapped. Geochemical data is also limited, and the deposits are not well-documented in geological literature. The nearby Ojuela district (Mapimí), however, is well-studied and broadly acknowledged as a series of high-temperature carbonate-replacement deposits (CRDs). A CRD typically presents two styles of mineralization: massive sulphides or skarns. The massive sulphides may transition into skarns with proximity to intrusions where marble recrystallization is also common. Podiform skarn bodies are considered to be the deepest expression of CRDs (Megaw and Titley, 1988).
These ore bodies typically present as mantos (flat-lying, bedded deposits, often strata-bound) or as chimneys. The mantos commonly occur at shallower depths and connect to chimneys (meandering, branching and irregular bodies) with depth (Prescott, 1926). Chimneys may pinch out downward or terminate at intrusive contacts (Megaw and Titley, 1988).
CRDs are epigenetic, intrusion-related, high-temperature, sulphide-dominant, lead-zinc-silvercopper-gold-rich deposits that commonly occur in clusters associated with major regional geologic features. The Mexican CRD Belt is considered to be one of the world’s best developed CRD clusters.
CRDs are not limited to the margins of intrusive bodies but may occur kilometres away from the intrusions interpreted to be the source of the hydrothermal fluids responsible for mineralization. Stratigraphy and structure are important controls and constitute the pathways by which mineralizing fluids reach a suitable host-rock for deposition. At Ojuela, lithology, folds, faults, fractures, and intrusive contacts determined sites of mineralization, wherein the massive sulphide style is the most common; as Ojuela is distal to the El Sarnoso stock, this fits with the CRD model (Megaw and Titley, 1988).
Galena, sphalerite, pyrite, pyrrhotite, arsenopyrite, chalcopyrite and marcasite are typical minerals found in the massive sulphides and the silver is thought to be present in the galena. The arsenopyrite and chalcopyrite are commonly found deep or nearer to intrusive bodies. Cinnabar, stibnite, acanthite, realgar and silver sulfosalts are found distally. Typical gangue mineralogy consists of carbonates, quartz, fluorite, barite, and anhydrite. Skarns show the same sulphides listed earlier but may include bornite, molybdenite, covellite, scheelite, powellite and cassiterite. In addition, magnetite and hematite may be locally present. When the host rock is carbonate in origin, gangue minerals in skarns are generally garnet, pyroxene, wollastonite, actinolite, epidote, chlorite, and quartz. Manganese oxide mineralization and dolomitization are common forms of alteration especially around stock contact skarns (Megaw and Titley, 1988). The Ojuela district appears to be particularly rich in manganese oxides (Hoffman, 1968).
Ana Maria and La Zorra align well with the CRD model. Along with being situated in a CRD district—the host rocks are carbonates—it occurs adjacent to an intrusive stock and shows skarn

and manganese oxide alteration with hematite and magnetite. Like Ojuela, gold mineralization is present alongside hematite and manganese oxides, and the sulphides present are those expected of a CRD.
The El Soldado projects (Paola, Jabilí and La Cross) and La Recompensa show less skarn alteration but are situated farther from the El Sarnoso stock. They display the same hydrothermal oxides and structural controls observed at Ojuela as well as ore mineralogy consistent with CRDs.

12 DATA VERIFICATION
There is no current exploration or development data in the creation of this Technical Report.
The Qualified Person visited the properties on January 20-22, 2021. The site visits included an inspection of the property, showings and outcrops including the iron-manganese outcrops at La Lucha showing and the calcium carbonate showings at La Recompensa and La Soldado and tours of major centers and surrounding villages most likely to be affected by any exploration activities and potential mining operation. No samples were taken as there was not any previous sample data to be validated and verified.The geological information used in the creation of this Technical Report was from publicly available sources and information provided by Silver Wolf and Avino which is supported by publicly available reports and is therefore deemed to be reliable by the Qualified Person.

25 INTERPRETATION AND CONCLUSIONS
25.1 ANA MARIA
The Ana Maria property is located 21 kilometres (km) northwest of the City of Gómez Palacio and the adjacent City of Torreón, and 1 km north of the town of Dinimita, in the municipality of Gómez Palacio, Durango, Mexico. The concessions are located in the Minitas mining district in the Guadalupe Victoria mining region. The property consists of 9 mining concessions encompassing 2,549.0 hectares (ha).
The region hosts a number of carbonate replacement deposits (CRD´s) within Cretaceous limestones and dolomites. Mineralization is associated with large stocks, dykes or sills of granitoids ranging from diorites to quartz monzonites and rhyolites and inferred to be lower crustal in origin. Mineralization is present as skarns or massive sulphides and occurred during MidTertiary volcanism when the aforementioned intrusions were emplaced (Megaw et al., 1988 and references therein). The deposits typically produce silver, lead, zinc and copper although some districts, such as Ojuela (~10 kilometres from Ana Maria and La Zorra), are enriched in gold relative to typical CRD´s.
The Ana Maria concessions are an early-stage exploration project that have some historic activity. The properties are prospective and warrant a systematic exploration program which includes geological mapping, sampling and geophysical techniques.
25.2 RISKS AND OPPORTUNITIES
Table 25.1 lists the potential risks and opportunities that may affect, hinder or otherwise impact exploration and development going forward.

26 RECOMMENDATIONS
The following two phased work program is recommended for the Ana Maria Project. They may be performed in series or in parallel, depending on resources and circumstances.
It is recommended that Silver Wolf complete geological mapping, surface geochemical sampling, TerraSpec sampling and geophysical surveys in addition to performing a Lidar survey. In addition, initial baseline environmental data acquisition and reporting should be initiated and is recommended along with continued ongoing implementation of an Ejido/community consultation plan. The view is that this work would support core drilling in the future.
The author recommends:
-
Surface mapping
-
Lidar survey
-
Airborne- and ground-geophysical surveys
-
Geochemical sampling
-
Surface sampling, mapping, and prospecting
Table 26.1 and 26.2 presents an ongoing exploration and development program for the Ana Maria property. The Phase 1 program recommends initial reconnaissance and data integration work along with performing a LIDAR and Terraspec survey. This phase will include data analysis and modelling to determine prospectively to test the validity of the CRD deposit model hypothesis. The Phase 2 program is contingent upon the results and relative success of the Phase 1 program which would then employ geochemical sampling and geophysical surveying techniques to assist in target identification and support the selection of drill targets to further advance the project.
Approximate expense items are listed with a description, where appropriate, and a total cost. The length of this program is approximately 24 months from inception through to completion of a status report. All costs are in $US.
