ABSTRACT:STRATIS was retained by Antler Hill Mining Ltd. (Antler Hill) to prepare a NI 43-101 Technical Report for the Cerro Blanco property. The Cerro Blanco property is located in the San Juan Province of Argentina, 113 km west-south-west of the provincial capital city, San Juan, and 42 km south-west of the town of Barreal in the Calingasta Valley. As of February 12, 2019, the most recent report outlining land tenure data, the Cerro Blanco property covered an area of 12,829.4 hectares (ha) and comprised seven contiguous mineral tenements (the tenements). The tenements included six exploitation concessions and one exploration concession. Entropy Resources SA (“ERSA” or “Entropy”) has 100% ownership of mineral rights for all the mineral tenures at the property. However, according to the most recent Land Title report, the transfer of mining rights for LEON I, LEON II, and CATEO 11224.030-B-2008 have not been registered in the government files. At the time of writing, the application to reinstate the mining rights to LEON I to Entropy was rejected by San Juan Mining Authority. Entropy is in the process of appeal to recover the mining rights to LEON I. It is noted here that the Los Gemelos Prospect is on the border to the LEON I tenement and not having access to the LEON I tenement will not affect exploration for the Los Gemelos Prospect. The Cerro Blanco property is located on the eastern margin of the Frontal Cordillera range and comprises a suite of intrusive and volcanic rocks, shales and schists and, to the southeast, Carboniferous sedimentary rocks showing incipient metamorphism. In the northern part of the property, these sediments are covered by recent erosional detritus. The assemblages were intruded by a number Tertiary porphyritic dacites. The Cerro Blanco property encloses several visually distinctive, circular, leached and hydrothermally-altered andesitic or dacitic porphyritic intrusive centers, identified as the Copper Hill, La Fortuna, Despoblados and Los Gemelos Prospects. These are in turn overlain by more recent dacitic tuffs. Field observations made by Dr. Pugliese in 2012 identified general structures such as tuff rings that are closely related to diatreme breccias, pebble dykes and volcanic outcropping sequences represented by lava flows and distal ignimbrites. These features were interpreted as evidence of a partially eroded “stratovolcano” and suggested the Copper Hill Prospect was emplaced as a telescoped porphyry system. To date, the Copper Hill Prospect has received most of the exploration attention.
