3 SUMMARY Jero Resources Ltd. holds 4 claims (Jero 1 to 4-40 claim units) in the Rossland Gold camp of southern British Columbia. The camp has the second largest record of gold production in the province. The claim area is underlain by sedimentary, volcanic and subvolcanic intrusive rocks of the Rossland Group which are intruded by northeast-trending dikes of quartz feldspar porphyry. No mineral occurrences are known on the Jero claims, however, preliminary work carried out during the period May 31 to June 3, 1983, has indicated the presence of widespread lead and zinc geochemical anomalies and several VLF electromagnetic anomalies. A program of futher geochemical soil sampling, and electromagnetic surveys and prospecting are recommended. CONCLUSION The presence of widespread lead-zinc geochemical anomalies plus confirmation of airborne electromagnetic anomalies indicate that further work is warranted to evaluate the Jero claims.

4 INTRODUCTION Jero Resources Ltd. holds 4 claims totalling 40 claim units in the Rossland gold camp of southern B.C. The claims were acquired by staking in 1982 and The claim area lies 4 kilometres south of the Centre Star, Le Roi, and War Eagle Mines (Centre Star group). These mines have the second largest recorded production of gold in British Columbia (2,706,000 ounces of gold, 3,300,000 ounces of silver and over 100,000 pounds of copper from 5,915,000 tons of ore). No mineral occurrences are known on the Jero claims. The claims were staked to cover an area of favorable geology and a weak electromagnetic anomaly indicated by an airborne survey (Sheldrake, 1981). This report summarizes results of five man days of work carried out on June 1 to June 3, 1983 by D.G. Allen, D. Cuvelier and A. Geoghegan. The work was designed as a preliminary step in evaluation of the eastern part of the claims and consisted of three lines of soil sampling and two lines of VLF-EM survey.

5 LOCATION, PHYSIOGRAPHY, ACCESS The claims are situated immediately to the south of Rossland (figures 1 and 2). They lie between 3100 and 4800 feet on the north slopes of Baldy Mountain. Slopes are gentle to moderately steep and are covered with a second growth of balsam fir, cedar, Jack pine, spruce, birch and scrub alder. The northwest corner of the Jero 3 claim covers some farmland. The claim area is accessible by several 4-wheel drive roads. CLAIM DATA The Jero 1-4 claims are registered in the name of Jero Resources Ltd. Claim data are as follows (see figure 3): - Name No. Units Record No. Tag No. Expiry Date Jero (6) June 8, 1984 Jero (6) June Jero (6) June Jero (6) June 8, 1984 Total 40 HISTORY The Rossland mining camp was the second largest gold producing camp in British Columbia. Total recorded production (mainly during the period ) 2,706,000 ounces of gold

9 and 3,300,000 ounces of silver from 5,915,000 tons of ore with an average grade 0.47 ounces of gold per ton and 0.6 ounces of silver per ton and 1% copper. Most production came from four deposits (Le Roi, Centre Star, War Eagle and Josie) in the core of the camp. Molybdenite was produced at Red Mountain during the period 1966 to GEOLOGY Regional Geology The Rossland area lies in the Nelson Map area, 82F (west half), the geology of which as been described by Little (1960). The geology of the Rossland Mining Camp has been well documented by Drysdale (1915), Bruce (1917), Gilbert (1948), Fyles (1970), Fyles et a1 (19731, Thorpe (1973) and Little (1982). In summary, the gold deposits of the Ross- land camp occur in a complex environment in which major volcanic, sedimentary and intrusive rocks occur. Oldest rocks are the Carboniferous Mt. Roberts Formation which consists of siltstone, sandstone, conglomerate and minor limestones. They are overlain by volcanic rocks and inter- bedded sediments of the Jurassic Rossland Group. Irregular bodies and dikes of augite porphyry was apparently coeval with the Rossland volcanics. These rocks are intruded by three groups of plutonic rocks, the Rossland monzonite, the Trail batholith (granodiorite), Coryell intrusions (syenite), Rainy Day stock (quartz diorite) and

10 a large number of dikes including diorite, lamprophyre, syenite, and quartz feldspar porphyry. Property Geology The claim area is largely overburden covered. are confined to road cuts and a few steeper slopes. Outcrops Accor- ding to Fyles ( see figure 4) the claim area is underlain by sedimentary and volcanic rocks of the Rossland Group (unit 2c, d, and e) and augite porphyry (unit 2f). Examination of a few outcrops on the road across the Jero 2 and 4 claims confirmed the presence of both argillite and greenstone, both containing abundant disseminated pyrrhotite. The main rock types observed were northeast-trending dikes of quartz-feldspar porphyry which, because they were more resistant to weathering, form small but prominent ridges. Ore Deposits The gold-copper deposits of the Rossland camp are predominantly pyrrhotite-rich quartz veins containing up to 70% sulfides. They are locallized by east and north-trending faults where they intersect or lie along contacts of highly competent rocks such as augite porphyry and diorite porphyry. Thorpe (1973) has defined three zones; central, intermediate and outer. Veins of the central zone have a high chalco- pyrite content and Au:Ag ratio, veins in the outer zone contain sphalerite,galena and tetrahedrite and have a lower Au:Ag ratio. Veins in the intermediate zone are charac- terized by a wide range of mineralogies including pyrrhotite,

11 chalcopyrite, arsenopyrite, pyrite, molybdenite, cobaltite, gold, bismuth and bismuthinite. The molybdenite deposits on Red Mountain occur in brecciated granodiorite and hornfelsic and skarny sedimentary rocks of the Mount Roberts formation. Mineralization consists of irregularly distributed disseminations and veinlets of pyrrhotite, pyrite, magnetite, molybdenite, scheelite and chalcopyrite (Eastwood, 1966; Fyles, 1967; Hainsworth, 1966). The Jero claims lie in the outer zone and are situated immediately south of the Lily May, Bluebird and Mayflower prospects. GEOPHYSICAL RESULTS I Two VLF-EM lines were run across the Jero 2 and 4 claims to carry out preliminary evaluation of airborne electromagnetic anomalies obtained by Sheldrake (1981). Preliminary results, as interpreted by D.R. MacQuarrie, consulting geophysicist,indicate two possible weak conductors (figure 5) that in general correlates with those obtained by Sheldrake. The data indicates the presence of a wide conductive zone which generally correlates that obtained by Sheldrake.

13 GEOCHEMISTRY Three lines of geochemical sampling were undertaken to carry out preliminary assessment of the claim area. Soil material sampled consists mainly of fine glacial till taken at depths of 10 to 25 centimetres, usually well below the A horizon. Samples were shipped to Rossbacher Laboratory Ltd. for multi-element analysis. Anomalous zinc values (150 to 250 ppm), lead (30 to 308 ppm), arsenic (20 to 350 ppm) along with a few weak gold values 20 to 30 ppb occur along the lines surveyed. Because of the wide spacing, no correlation of anomalous values can be made between lines.
