Follow this mostly-paved road for 20 km until you reach the town of Bellavista. From the municipality of Bellavista the mine is 1 km away through an unpaved road.  The project can also be accessed through the Amaga - Angelopolis road, a 20 km drive (unpaved).

Mineral(s): Coal

PROJECT DESCRIPTION

The project area is located between 1,700 to 1,800 masl and has a 1:1000 scale topographic survey. The mining area has been mined intermittently by artisanal miners for over 20 years, with an annual production below 2,000 tons. The existing mining operations have been accessed through inclined tunnels with slopes inclined less than 40 ° and lengths below 300 m, the exploitation work that has been executed in the area has been done with the room and pillar method. There is a reel that goes to the two existing mine shafts, in addition to electric supply, the other infrastructure is minimal.

Local and Regional Geology: The area is located in the Amagá formation which has a sedimentary sequence in North-South direction, which rests discordantly on crystalline rocks, such formation has three members, leaving the project area in the Middle Member Tsm, which has the highest importance by being the carrier of the coal deposits. It is characterized by the presence of thick coal seams greater than or equal to 0.60 meters, intercropped in a sequence of locally carbonaceous clay siltstones and sandstone. It has an average thickness of 200 meters in the sedimentary sequence between Angelópolis and Amagá.

Economic Geology: In the area outcrops the sedimentary sequence of the middle Member of the and Amagá formation, which includes the following mantles: La Primera, La Segunda, Lista de la Tercera, La Tercera, La de 4 Buena, La de Tres, 4 Cachuda, 4 Dura y Quinta. However, only five of the mantles listed are susceptible to exploitation due to their thicknesses, which are between 0.6 meters to 0.95 meters.

Quality. The coal mantles found in the project area have the following qualities. Ash: less than 7.04%, heating value: between 10,580 and 11,554 BTU/lb; Sulphur: less than 0.55% except cachuda mantle which has a content of less than 0.93%, humidity: 10% to 11% and volatile content: 40% to 43%.

Reserves: Basic reserves measured are in the order of 597,000 tons and indicated basic reserves are in the order of 528,514 tons.

Treatment Plant – Transformation: There is currently no infrastructure for processing material.

Infrastructure: El proyecto cuenta con una boca de mina, malacate, carrilera, depósito y planificación para la instalación de clasificador y futuro túnel principal.

Title Number: 6204 Y 14440

Title Holder: CALDESA S.A.

Title Area: 500 Ha

Department: Antioquia

Municipality: Puerto Nare

Location and Directions:  The area of exploitation is located in the vereda of Caño Seco, district of La Sierra that belongs to the Municipality of Puerto Nare, Antioquia. The area corresponds to the mining titles 6204 Caño Seco I and 14440 Caño Seco II with a total area of 500 hectares. You get to property by taking the Highway Medellin - Puerto Berrio - Puerto Serviez and from there by river passing Boyacá department to the urban district of la Sierra, site in the department of Antioquia where the production plant is located. From this point take the road between La Sierra and Puerto Nare, 4 kms before reaching the urban area turn right taking the road to the municipality of San Carlos, the mine is located at the right hand side of the road on the vereda Cano Seco. Total distance is approx. 15 km from the district of la Sierra.

Mineral(s): limestone

PROJECT DESCRIPTION

Local and Regional Geology: The lithologic units are composed mainly of metamorphic rocks of the Cordillera Central, grouped under the so called "Cajamarca Complex." This group consists mainly of feldspathic gneisses and aluminous gneisses, quartzites, marbles and amphibolites, under low-pressure metamorphism from green schist facies to amphibolite high facies during the Paleozoic.

It also presents thermal Metaformism result of the intrusion of the batholith of Segovia. Within the framework of the local geology the following lithological units stand out: Igneous Rocks: Distributed in no particular order in the field of study, occurring as dikes, intruding the bodies of marble with a small plutonic bodies. Basic dykes are observed (Andesite) and plutonic rock (diorite).

Among the metamorphic rocks the following are seen: quartz Muscovites schists (sericite), graphitic schist and chlorite schist surrounding the marble body to the SW, SE and NE, Quartzite in interleaving consistent with the schists, and marbles that are as an irregular body extending from the center to the NW and SW of the area of study, covering an area of approximately 2.5 km.

In some areas the marbles are interleaved with bands of quartzite with fine to thick grain and color ranging from dark gray, almost black to white. Recent deposits are composed of colluvial deposits and alluvial deposits, the colluvial are located in the slopes, filling spaces in the cracks of the bodies of marble and boulders, while the alluvial deposits are related to the creek named “Crystal” and other streams such as Creek “Caño Seco”.

Economic Geology: The deposit of interest belongs to a large body of marble in depositional contact both East and West with schists interbedded with quartzite. This deposit usually develops very little soil due to the kinetics of dissolution processes, transportation and steep slopes that prevent the preservation of the product of weathering

Reserves: Estimate of existing resources in the deposit, for a total of 215, 628,168.57 tons.

Treatment Plant – Transformation:   The exploitation system is done by open pit mining. For drilling work two diesel compressors and 4 pneumatic hammers are used, ANFO is employed as the explosive material for blasting.

CALDESA sells hydrated lime, agricultural lime, mixed sulphiding (lime and dolomite), quicklime, and fine crushed limestone.

Quicklime, hydrated lime and sulphiding mix are part of the processed product, whose production is 30.744 tons per year. Agricultural lime and crushed limestone have an annual production of 1.945 tons.

Infrastructure: The area does not have public transport from the village to the mine. The Corregimiento La Sierra has electricity, aqueduct and telephone. The mill is supplied with electricity by the power plant of the company Argos (Plant Puerto Nare).

The project is located next to the Magdalena River, the country's main waterway that allows the transport of ore to the Atlantic coast; this also becomes an advantage for contacting other departments in the Country.

Environmental Aspects:  The water sources that are closer to the mine sector Caño Seco I and Caño Seco II are the La Crystalina creek, the Caño Seco Creek and other small creeks. In the exploitation process these water resources are not used, the facilities of the mill are located on the right bank of the Magdalena River.

Comments: All products are certified under norm ISO 9001:2008 from ICONTEC.

TITLE INFORMATION

Title Number: KBH-15521

Title Holder: Juan Diego Cadavid A.

Title Area:  296,2088 Ha

Department: Antioquia

Municipality: Abejorral

Location and Directions: The Project is located in the Municaplity of Abejorral, within the limits of the municipality of Sonson and Aguadas, at the district “La Parima”, on  la Guayana Farm. To get to project from Medellin you must take the road from la Ceja to Abejorral, a 90 km trip on a paved road.
It has 3 access roads which are: Through the municipality of La Union, the Municipality of La Ceja through “el Gauaico" and by the southwest through the municipality of Santa Barbara (through el Cairo). There are very good transportation options available from these municipalities to Abejorral.

Mineral(s): Gold and its concentrates.

PROJECT DESCRIPTION

Local and Regional Geology: According to Scheibe (1934), occasionally, granite rocks have gneissose (Gn) or cataclastic structures and form shapes that are more reminiscent of schistose gneiss or with micaceous schists than with granite itself.  In this case, the plutonic body is injected into fine veins of the schists, it is fine-grained and it displays sometimes sheets of graphite and muscovite and garnet crystals with minor biotite but high hornblende, which differentiates it from the granite rocks of the central region.

The generalized geologic map that accompanies the work of Scheibe (1934), shows between Aguadas and Abejorral some of these bodies (Gn), that correspond to the so-called gneisses of Abejorral and Pantanillo (González, 1976, 1980) and concludes that these bodies correspond to eruptive gneisses or even granite gneissic structures, which owe their foliation probably not to a dynamic transformation after its crystallization, but rather to the pressure experienced and the subsequent intrusion process in the schists along the parting plane.

Scheibe (1934), based on the so called Jurassic-Triassic formation, believes that both the granitic bodies (G) and the granites with gneissic structure (Gn), are posterior in time and therefore relatively young, but preceding the Tertiary Coal formation that is in part covering them.

For Grosse (1926), part of the fundamental  archaic  land of the Cordillera Central in Antioquia was intruded by masses of plutonic rocks of a granitic nature from the  pre Paleozoic or Paleozoic age, characterized by having undergone a more or less intensive metamorphism and whose age can only be said with certainty that, at least, are pre cretaceous perhaps eopaleozoic  to Precambrian, because they do not  cross the porphyritic formation of the Jurassic - Cretaceous and probably belong to periods of intrusion and folding of different ages, as their metamorphism can vary from one body to another.

Grosse (1926) describes these bodies and separates them according to their structural characteristics, composition and extension, as Muscovites glandular gneisses, lenticular granitite, lenticular granitic and granite intrusions, granodiorite and diorite. All these bodies are generally elongated and have evidence of an intrusive formation, forming halos of variable thickness in contact with the slates and archaic schists, and there are often found inclusions that are transformed into biotite hornfels.

Economic Geology: Abejorral municipality has deposits of kaolin, clay, manganese, volcanic ash and other metals such as gold.

Reserves: The area has no geological studies that can determine the amount of minerals.

Treatment Plant – Transformation: At the moment there is no exploration / exploitation work. Guayana project should initiate the process of exploration.

Infraestructure: Área disponible para campamento, túnel con dos vetas de 20 cm cada una y avance de 145 mts. Area available for a camp, tunnel with two veins 20 cm each and advancement of 145 mts.

Environmental Aspects: The PTO (Work and construction program) to show the scope of the project and determine the possible effects to the environment and how to mitigate them has not been done yet.

Comments: The project Guyana requires detailed geological studies to determine the true potential for the development of an operation.

TITLE INFORMATION

Title number: KF3- 09231

Title Holder: Luis Alberto Posada Callejas

Title Area: 150 Ha

Department: Antioquia

Municipality: El Retiro

Location and Directions:  The project is located in the municipality of el Retiro, vereda Santa Elena. To access the area take Las Palmas highway from Medellin to the municipality of El Retiro, 2.7 km after the dam La Fe turn left.

The area is characterized by being located at a site near the city of Medellin, has all the services and infrastructure needed for the development of a project.

Mineral(s): Gold, Silver, building materials and other minerals.

PROJECT DESCRIPTION

Local and Regional Geology: The metamorphic basement of the axis of the Cordillera Central surrounding Medellin is composed of metabasites and high-grade gneisses, associated with low-grade schists(Botero, 1963, Echeverria, 1973; Restrepo & Toussaint, 1984).  Botero (1963) grouped these rocks into the Ayurá – Montebello Group, which was subdivided by Echeverria (1973) in Ayura Zone for high grade, and the Montebello Zone for the low grade.

Restrepo & Toussaint (1982, see also Restrepo et al., 1991) identified several metamorphisms superposed on the  metamorphic of the range, Devonian Carboniferous events , Permian-Triassic and Cretaceous, propose to rename the unit as polymetamorphic complex of the Cordillera Central. Indeed, recent geochronological work with U-Pb Shrimp system supports the idea of the  polymetamorphic state of the  unit (Ordóñez, 2001; Vinasco et al., 2003). The complex includes larger bodies of amphibolites (Figure 1)that  are grouped under the name Amphibolites Medellin (Restrepo & Toussaint, 1984),due to  its location near the city.

Dating of these rocks, as obtained by Restrepo (1991), served as the basis for proposing a Cretaceous metamorphic event, it was suggested that metabasites be correlated with Arquía Complex rocks, corresponding to the basic part of an ophiolite that would have been metamorphosed in a Cretaceous  subduction zone (Toussaint, 1996 ).

McCourt et al. (1984) studied Arquía Complex rocks to the south of this zone, and they are not consistent with a Cretaceous age for the metamorphism, but  are consider Paleozoic or earlier. Recent Ar-Ar dating of amphibolites Medellín (Martens & Dunlap, 2003) indicate that the Cretaceous ages obtained are due to thermal perturbations caused by the intrusion of large Mesozoic plutons such  as Antioquia Batholith, the age of the metamorphism would be older, possibly within the Permian-Triassic period.
(C.Central) does not end in snowy or volcanic peaks, the geometric figure which describes the region is a truncated pyramid in the middle. What characterizes the Central Cordillera in Antioquia is the presence of extensive plateaus and the absence, therefore, of peaks and mountains in the central area. The different phases of the lifting of terrain in Antioquia are certainly recorded from different layers provided precisely the highlands of Antioquia, of which the oldest are those of the valley of La Union.

Economic Geology:  The area is on material derived from igneous rocks that form the so-called Antioquia batholith that formed in the Mesozoic Era during the Cretaceous Period. This is formed by the complex of cuarzodioritas, andesite, granodiorite, gravels which are a granitic magma.

In the project multiple veins have been identified, in laboratory studies with the ministry of mines tenors of 5 grams of gold per ton and 8 grams of silver per ton were identified. Complete lab results are available for investors.

Reserves: The project requires a detailed study to define the amount of reserves

Treatment Plant – Transformation:  the area has no infrastructure intended for the benefit and transformation process.

Infrastructure: The title has exploration tunnels; the sector has electricity, water and paved roads.

Comments:  The project LUISINES due to the proximity to the city of Medellin, has great advantages from the viewpoint of attaining equipment, facilities and machinery.

Location and Directions: From Medellin to get to the mine take the Medellin Sonsón route, exiting the main road at km 57 and continue along this secondary road 1.5 km to reach the deposit.

Mineral(es): Clays.

PROJECT DESCRIPTION

Local and Regional Geology: In the project area are two types rocks outcrop: metasediments of the group Ayurá Montebello, of which predominate in this area the pelitic schist, quartzite schists and to a lesser extent, graphitic schists.

Metamorphic rocks occupy almost the entire area.

Tonalite: apophysis of Platonic rock with tonalitic composition, whose deep weathering has resulted in the kaolin deposit identified in the south east of the title area. It is not possible to recognize the bedrock, or its saprophytic, but the presence of dykes and quartz crystals and intensely weathered mica allows us to propose the occurrence of this type of lithology.

The area of ​​the tonalitic intrusion reaches a maximum of 12 ha of the total area explored.

The area has its largest outcrops in the eastern part of the title in an area of ​​12 ha, according to the report from the mining title.

Economic Geology According to perforations made, there is a layer of volcanic ash of variable thickness, between 1.0 to 1.5 m, thereafter occurs a horizon of clays, some of which vary from white, red, yellow gray, and dark cream, all of these have varying thickness between 1.0 to 7.8m, these clays are caused by decomposition or deep weathering of the plutonic origin rock.

It is worth mentioning that the information is based on the maximum depth of the manual drill, therefore the depth of the fresh rock and total clay column horizon is unknown.

Reserves: In terms of reserves currently drilling has been made which reached depths of 11m in an average area of 11000 square meters, quantifying a volume of 75,000 tons the first year of exploitation (according to data record).

Treatment Plant – Transformation: Currently for processing minerals there is no equipment.

Infrastructure: There is currently no mining infraestructure.
