Point Location Description: DDH 1 on claim L30180
Location Method: Based on Assessment
circa-1925: Roche claim (no. 11290) - stripping, blasting, and trenching exposed a 10-12 foot wide 'disturbed' zone which is silicified and Fe-carbonate altered; assays ranging from 0.03 to 0.06 oz/t Au returned from a rusty schist. 1946-1947: Hoyle Mining Co. Ltd. controlled 40 contiguous patented mining claims in northeast central Harker Township. Hoyle Mining Co. incorporated Lightval Mines Ltd.: ground magnetic survey, DD-12-6879 ft. 1986-1989: Newmont Exploration of Canada Ltd. - property optioned; 1989: Newmont Exploration of Canada suspended its Canadian operations, formed a joint venture with Noranda Exploration Ltd. to explore the Teddy Bear Valley Mines and Lightval Mines claim groups, and diamond drilled.

Jun 29, 2015 (D Guidon) - Kimberlite is reported to have been intersected by Newmont Exploration. DDH 225-88-6from 265.47 - 266.91 m; 225-88-7 from 143.10 - 167.90 m; 225-86-1 from 53.37 - 53.77 and possibly hole 225-88-4 from 60.40 - 60.50 m.
Jun 29, 2015 (A Wilson) - Neoarchean supracrustal rocks, which are intruded by Paleoproterozoic and Keweenawan-age diabase and Mesozoic kimberlite dikes and pipes, underlie the Highway 101 area. Narrow (up to 2 m wide), discontinuous lamprophyre dikes occur most commonly near the Porcupine.Destor deformation zone, but are also found throughout the study area. These dikes are inferred to be younger than the lamprophyre described above based on crosscutting relationships with all rock types except the Paleoproterozoic dikes, Keweenawan-age diabase and the Jurassic kimberlite intrusions. Most dikes at surface are orange brown and recessively weathered due to extensive carbonatization and less common hematization. These rocks are composed of mainly biotite and/or phlogopite phenocrysts (up to 2 cm in size in some dikes) with amphibole, carbonate, feldspar and chlorite confined to the groundmass. Satterly (1948) first noted the occurrence of kimberlite in the study area. Since then, several kimberlite dikes and intrusions were discovered as a result of gold exploration programs. Sage (1996) documented the major kimberlite occurrences in the study area and provided mineral geochemistry for some of the intrusions. All kimberlite intrusions are situated between the Arrow fault (local name) and the Porcupine Destor deformation zone with the greatest number occurring near alkaline intrusions. Kimberlite dikes occur in Harker, Garrison, Michaud and Guibord townships.
Dec 07, 2005 (R Degagne) - Bedrock in the area consists mainly of weakly metamorphosed (greenschist or lower metamorphic facies) volcanic, tuffaceous, and sedimentary rocks of the (Archean) Hunter Mine and Stoughton-Roquemaure Groups north of the PDFZ; of volcanic and interflow sedimentary and/or tuffaceous rocks of the (Archean) Kinojevis group south of the PDFZ; and of a lithologically and structurally complex assemblage of supracrustal and intrusive rocks of the (Archean) Porcupine-Destor Complex within the PDFZ.

Jun 29, 2015 (R Degagne) - Gledhill reported that a sample collected from a quartz vein in 1925 assayed up to 0.03-0.06 oz/t Au. The Lightval Mines diamond drilling intersected narrow (ranging from several to several tens of metres in apparent thickness) variably pyritic fractured, brecciated, silicified, feldspathized, cherty, and yellow to purple colored zones within and/or marginal to (and within Kinojevis Group rocks) south of the PDFZ.

Notes: Although no gold assay data accompany these logs, a brief report by W.C. Martin (assessment files) states that assays as high as 0.06 ounce of gold per ton are associated with such mineralization. The descriptions of these zones which appear in the drill logs are broadly similar to descriptions of (American Barrick Resources Corp.) Holt-McDermott type mineralization which occurs marginal to or within the PDFZ in western Holloway Township, and along laterally extensive deformation zones within the Kinojevis Group stratigraphy south of the PDFZ in the Harker-Holloway Township area.
