LocationThe Maijoma claim is located in northern Mexico, 65 kilometres southeast of Ojinaga, Chihuahua State, and is very prospective for the discovery carbonate replacement deposits (CRDs) and skarns. Over 2,890 hectares (11 sq. miles) in size, the claim is easily accessed by paved and gravel roads.
Exploration work to date, comprised of an airborne magnetic and radiometric survey, a ground gravimetric survey, an I.P. survey, geological mapping and rock sampling, has identified several large-scale areas of alteration and mineralization in a well-defined east-northeast trending structure that extends for more than 8 kilometres. Camino believes that the mineralization is the high-level expression of a major carbonate replacement hydrothermal system (CRD) hosted in a thick sequence of favourable Cretaceous limestones.
In 2010, Camino completed an airborne magnetic and radiometric survey over Maijoma, which helped define several major regional structures. These structures include large circular features, several tens of kilometres in diameter, as well as an east-northeast trending corridor, which hosts the Maijoma hydrothermal system. The corridor hosting the Maijoma system is situated on a splay from a major east-northeast trending crustal structure that extends across northern Mexico to the southern edge of Shafter District, located in Texas approximately 100 kilometres north of Maijoma. The Maijoma system is positioned near the junction of the crustal structure and a prominent northwest trending regional fault that extends north to the Shafter District. Regionally, structural intersections control major mineralized trends that can be seen at Santa Eulalia, to the west, and the Shafter District, to the north.
Santa Eulalia, located approximately 170 kilometres west of Maijoma, was first discovered by the Spanish in 1591 and has produced approximately 12,000 tonnes of silver (423,287,544 ounces of silver), 3 million tonnes (6.6 billion pounds) of lead and 2 million tonnes (4.4 billion pounds) of zinc. The Shafter District, located approximately 100 kilometres north of Maijoma, was discovered in 1883. The principal mine in the Shafter District is the Presidio, which is reported to have produced nearly 36 million ounces of silver and 8,400 ounces of gold (base metal content was not reported). Aurcana Corporation has restarted work at Presidio and has reported reserves of 19 million ounces of silver and measured and indicated resources of 24 million ounces of silver. Past production, and current reserves and resources, at the Shafter District amounts to almost 80 million ounces of silver.
In June, 2013, Camino carried out a ground gravimetric survey over a portion of the east-northeast trending corridor that hosts the Maijoma system. A total of 634 gravity points were taken covering an area of 490 hectares (1.9 sq. miles). The survey outlined two gravity anomalies, one to the northeast and one to the south. Both areas coincide with anomalous silver, lead and zinc values obtained in rock sampling. The anomaly to the northeast, measuring approximately 1,500 metres by 200 metres, also corresponds with a limestone window overlain by younger ignimbrites of the upper volcanic sequence and a series of I.P. chargeability anomalies. Combined, the geology and the gravity and I.P. anomaly, strongly suggests the presence of sulphide mineralization. The southern gravity anomaly corresponds with strongly altered dacite porphyry intruding into strongly metasomatized limestones. The alteration is characterized locally by the presence of abundant green-to-pink garnets and vesuvianite in both the intrusive and the sediments. Jasper replacement layers are developed in the sediments along contacts with the dacite porphyry. These strata bound formations are strongly anomalous in zinc, with lower lead and silver values, and are believed to represent the distal portion of up flow zones that may be grading into massive sulphides at depth.
A reverse circulation drilling campaign is planned early in 2014 to test both the northeast and southern anomalies.
Camino holds a 100% interest in Maijoma, subject to underlying finder's fees with La Cuesta International (a privately owned company whose two principal partners are Perry Durning and F.L. "Bud" Hillemeyer).
