The targets at Ramard are polymetallic skarn and epithermal Au/Ag deposits.
Location and Setting
The Ramard project is located approximately 80 kilometers northeast of Hermosillo, northern Sonora, Mexico.
The property consists of seven claims totaling approximately 7,883 hectares controlled 100% by Millrock, subject to production royalites of 1.5% on gold and 1% on other metals.
Geology and Mineralization
Bedrock in the project area consists of quartzite and carbonate of presumed Proterozoic to Mesozoic age, overlain by andesitic volcanic rocks. Sediments and volcanics are cut by a series of intrusive rocks including potassium feldspar and quartz-rich porphyry, and capped by felsic ignimbrites of probable Tertiary age. The porphyritic intrusions are clearly related to mineralization on the property and have generated large bodies of calc-silicate skarn containing Ag-Pb-Zn mineralization and also Cu-rich, metasomatic mineralization in the older volcanic rocks. The porphyritic rocks also host polymetallic veins with local, high-grade gold and silver.
Areas of mineralization are widespread in the northern parts of the Ramard Project area. The largest is a zone of calc-silicate skarn measuring approximately 1,800 m by 700 m containing zones of significant Ag-Pb-Zn mineralization occurring as disseminated galena and/or iron and manganese oxides. Adjacent to the northeast are zones of epidote-rich alteration occurring in volcanic rocks with significant Cu grades and locally anomalous Au and Ag. This mineralization typically occurs in restricted, pod-like deposits with no clear structural or stratigraphic host defined to date. Roughly two km further west, mapping and rock sampling have defined a quartz porphyry body exposed over a two km by 600 m area, which is open to the north. Zones of quartz veining containing anomalous gold and silver values occur in and adjacent to the margins of the porphyry. The southern part of the porphyry hosts narrow quartz stringers which yield low grade gold (0.1 to 0.5 gpt Au) in chip samples and up to 2.5 gpt Au from select vein samples. Further south a float train generated by sub-cropping quartz veins containing polymetallic mineralization returned high-grade precious metal values ranging from 9 gpt Au and 54 gpt Ag to 180 gpt Au and 369 gpt Ag. The new northern claims have seen only limited exploration but historic bedrock gold workings in quartzite and placer gold from alluvial material have been noted. The southern Ramard block has no defined in-situ mineralization but sampling on the adjoining claims returned anomalous gold and silver, and a single stream sediment sample returned a value of 1500 ppb Au in association with magnetite-epidote altered float boulders.
The Ramard project is a large claim block with excellent access and infrastructure. The claims cover a variety of host rocks, including a series of quartz porphyry intrusions, with associated polymetallic skarn and precious metal mineralization. The area containing high grade gold/silver veins warrants a soil survey as well as further prospecting and mapping in those areas which have seen little or no exploration to date.
Agreement and Terms
Millrock controls 100% of the Ramard claims and is currently seeking potential joint venture partners. If desired, Millrock can serve as operator on behalf of an earn-in partner.
