-1- INTRODUCTION T'he Horn property comprises a group of forty contiguous claims owned by Canadian Superior Exploration Limited. The group is located five miles nort'h of Motase Lake. In July and August, 1974, crews of Ducanex Resources Limited conducted exploration surveys on the property. This report is a compilation of data obtained during surveys combined with a discussion of results. SUMMARY Work done in 1973 by Canadian Superior Exploration Limited on the Horn claims indicated the occurrence of interesting molybdenum values in soils. Work this year, 1974, done by crews of Ducanex Resources Limited, was designed to track down the source of the molybdenum values. Geological and geochemical surveys were more detailed than those surveys of the previous year. The 1974 programme included trenching by 'hand, but deep overburden in the / prime areas of interest limited the value of this trenching. Therefore, drilling of the prime target zones is recommended for the 1975 season. 1.t I I
tributary of the Squingula River, 5 miles north of Motase Lake, approximately 100 miles north of Smithers, B.C. Elevations on the property range from 3,000 to 5,500 feet with differences of 1,500 feet over half a mile not unusual. Lower slopes on the property are characterized by stands of mature spruce and balsam separated by large patches of sitka alder, while intermediate slopes are covered with dense growths of mountain hemlock and stunted, gnarled balsam. Timber line is near 4,500 feet. Snow-free months are generally mid-june to mid- September for much of the property, but on the north-facing slope, where much of the 1974 work was done, snow persisted until late July at higher elevations. Access to the property is via fixed wing aircraft to Bear or Motase Lake and then by helicopter to the property, / During 1974 a wharf at a hunting cabin near.the north end of Motase Lake was used as a trapsfer point between fixed wing and helicopter transport. On the prop- erty only one helicopter pad, situated near Horn Creek, was used in 1974. This one helicopter pad is well situated.lp for next year's programme on the property.

I Some faulting is coincident with the intrusive contact, but at many locations the granodiorite has an irregular contact with hornfels with embayments which are suggestive of an assimilation contact. 1 I ECONOMIC GEOLOGY 1 I 1 Features of the economic geology of the property, I I I 1, have been remarked upon under many of t'he other titles in t'his report. Here, I will try to lump the whole question of economic geology into one statement. I I! I Molybdenum appears to be the only element of economic interest on the property. It is widespread and I has several modes of occurrence, but the most interesting is the occurrence of molybdenite in hornfels. Near the intrusive contact t'he hornfels has been fractured and. then mended with quartz veinlets (2mm. ) Molybdenite has I / been introduced into the rock/with these quartz veinlets and it is found both wit'hin t'he quartz and disseminated into t'he rock adjacent to the veinlets. Molybdenite on the property is almost always associated with quartz veining, but what is necessary for an economic deposit is.t enough quartz veining per unit of rock to bring the

Sites for trenches were selected taking geology, geochemistry and overburden cover into account. In many locations trenches reached bedrock and revealed important information for mapping geology, although most molybdenum assays were low. Along the northern intrusive contact zone where information is most needed,.overburden is 10 to 20
