Here is the latest press release on Hornby. Looks like they have a large system, but also a lot more work to do!
SIGNIFICANT ZINC SULPHIDE MINERALIZATION ENCOUNTERED IN DRILLING AT ROSE GARDEN LAKE, NUNAVUT TERRITORY
Zinc sulphide mineralization has been encountered in multiple horizons over a strike length of 800 m (2,600 feet) in the recently completed Phase 1 drilling program at Rose Garden Lake. This program, comprising approximately 2,750 m ( 9,000 feet) in 24 holes, was designed to test surface showings and associated soil geochemical anomalies. The holes were drilled to a vertical depth of approximately 100 m (330 feet). The mineralization is open to depth and also along strike in both directions. As reported in Press Release 99-04 (July 26th) the initial three hole fence, drilled from west to east across the favourable argillite unit encountered intermittent narrow high-grade intersections within a wider envelope of low-grade mineralization over the 200 m (660 feet) wide fence.
Diamond drill holes DDH 99-04 through DDH 99-24 were drilled to investigate the soil geochemical anomalies and mineralized showings discovered during the exploration of a very small part of the favourable geological unit at the end of the 1998 field season.
Assays have been received for 13 of the 24 holes and show a wide envelope (up to 90 m intersected to date) of low grade zinc mineralization. Within this envelope narrow and higher grade intersections (up to 20% Zn) are present. In hole 99-11 a 6.5 m (21 feet) section grading 9.00% Zn occurs within a wider lower grade section. In the interest of saving time and money those cores described in the field as carrying visually estimated "low grade" mineralization will be logged, split and stored until freezeup when they can be flown out in a large wheeled aircraft for assay. A program of check assaying has been initiated.
Until much more exploration has been carried out, it is difficult to determine how the intercepts fit into the larger mineralized system. Our technical team is of the opinion that the near surface mineralization intersected to date may represent leakage from possible stratiform or VMS deposits at depth.
Management views the discovery of this extensively mineralized zinc system as of major importance. Crackle transgressive mineralization, sulphide cemented breccias and high grade remobilized multiple stage zinc sulphides may represent leakage from a deeper seated deposit. The drilling to date, together with prospecting and soil geochemical surveys, illustrate the extensive nature of this mineralized area at and near surface. The next drilling phase will test the concept of a source horizon at depth within the favourable middle Proterozoic argillite unit.
The geological setting of this exploration project within Proterozoic argillites proximal to major regional structures is analogous to the settings of some of the world's largest base metal deposits,(Cannington, Century, HYC and Sullivan) each with reserves ranging from 50 million tonnes to well in excess of 200 million tonnes.
Only a very small part of the >15km long favourable argillite belt has been sampled to a shallow depth by the current drilling program. The prospects for several styles of mineralization at depth are considered to be excellent.
The extent of the zinc mineralization over the strike length and widths seen to date within the mineralized corridor are viewed as of greater importance than individual assays. This zone is open in both directions along strike and to depth. |
