Dec 07, 2005 (C Salo) - The Hastings group straddle the Porcupine-Destor Fault Zone in the general area where it joins the west of west northwest striking Monro/Pipestone Fault Zone. The Porcupine- Destor/Monro/Pipestone Fault Zones is complex, consist of juxtaposed lithologically and structurally distinct fault/ear bounded blocks up to several hundred metres in size which in aggregate comprise a zone several kilometres in width. The regional metamorphic grade in the area is greenschist of lower metamorphic facies except marginal to felsic intrusions, where amphibolite grade contact metamorphic aureoles may be developed. North of the PDFZ, basement rock consist mainly of modernly north dipping and north facing volcanic, volcanoclastic, and sedimentary rocks, of the calc alkalic (Archean) Hunter Mine Group and younger, komatiitic and tholeiitic volcanic and intrusive rocks of the Archean Stoughton- Roquemaure Group. South of the PDFZ mainly northeast striking, steeply south dipping, and south facing tholeiitic basalt of the Archean Kinojevis Group occupies the north limb of the east striking and east plunging Blake River Synclinorium. The PDFZ is a regionally nonhomogeneous assemblage of juxtaposed fault/sheared bounded blocks, each of which may be distinct structurally and lithologically form the surrounding blocks. Mafic to ultramafic domains believed to represented faulted blocks of Stoughton-Roquemaure Group rocks as well as clastic, tuffaceous and chemical sediments and Interbedded alkalic volcanic rocks are also represented with the PDFZ. Intrusive rocks, including dikes of syenite, syenodiorite, granodiorite and monzonite, occur within the PDFZ and often are enclosed within extensive alkali, CO2, and H2O metasomatic aureoles. Garrison Stock which is a large (4 km wide) felsic monzonitic intrusion which is weakly metamorphosed (greenschist or lower metamorphic facies) subaqueously deposited massive and pillowed tholeiitic basalt and volumetrically minor intercalated interflow.

Dec 07, 2005 (C Salo) - Anomalously gold tenors, some of which have been reported as high as 2-3 ounces Au per ton, were obtained from and/or near a northeast striking and subvertically dipping shear developed at the contact between clastic sediments and porphyritic intrusive body. The Shear is reported to be pyritic and carbonate bearing, with carbonatization and sulfidation of the sediments. Ddd indicates that the alteration zone is a least 150 feet wide and depth and that is bounded on both sides by porphyritic dikes. Lamprophyre dikes and aplitic dikes as well as quartz veins and stringer are reported to be developed with this carbonate zone. The porphyritic intrusive body with which the shear is associated is reported to have yielded a gold assay of 0.06 ounce of gold per ton. The southern part of Hastings group has anomalously elevated gold tenors reported to occur in the native state as tiny specks associate with pyrite cubes within hematitic and or specularitic syenite. Chalcopyrite, galena and free gold are also reported to have been yielded by ddh here and to occur infrequently within quartz-carbonate veins. This drilling also encountered anomalous quartz-carbonate veins hosted by basalt, syenite porphyry, sensitized greenstone, pyritic syenite, pyritic felsite, pyritic serpentine, sheared and carbonatized pyrite syenite and sensitized green carbonate.
