Hawkeye Gold Corp - Strong potential for kimberlites on Front Range property Hawkeye Gold Corporation HAW Shares issued 5215314 1998-04-27 close $0.34 Tuesday Apr 28 1998 Mr Greg Neeld reports Hawkeye considers the Front Range property to be highly prospective for diamond-bearing kimberlites or lamproites. The mineral permits which are in the vicinity of Cadomin, Alberta, exist immediately adjacent to the Snowbird Tectonic zone, a major crustal lineament that extends from Baker Lake, NWT to under the Rocky Mountains of central Alberta near the southern boundary of the mineral permits. Work conducted by the Alberta Geological Survey indicates that this major crustal structure has been reactivated during several periods of Phanerozoic tectonic activity and therefore could easily have provided the deep-seated pathways that are necessary to allow kimberlitic or lamproitic magma to ascend to surface. The mineral permits are predominantly underlain by the Wabamun basement terrane, which is an accreted Proterozoic terrane that is similar in character and age to the Buffalo Head Terrane. The Buffalo Head Terrane is the basement terrane that is the underlying basement to the Buffalo Head Hills kimberlite discovery area. The Wabamun Terrane may at one point have been attached to or part of the Buffalo Head Terrane and similarly may also have an Archean component. Extensive seismic data for the area indicates that the Front Range property is underlain by more than 50km of crust, likely the thickest area of crust in Alberta. Anomalous thick crust such as that which underlies the Front Range property is considered a prerequisite for the formation and preservation of diamonds in the upper mantle. The Front Range property is also underlain by a prominent residual gravity low similar in magnitude to the gravity low that underlies the Buffalo Head Hills discovery area. This corroborates the seismic data and may indicate the existence of locally thickened crust beneath the Front Range property. Other geological data for the Front Range property indicate that the property has strong potential for the discovery of kimberlites or lamproites. This data includes: (1) the property exists approximately 100km northeast of a known diamondiferous lamproite, (2) diamondiferous diatremes elsewhere in Canada and the world exist in clusters over large area (in some cases 200km by 150km as illustrated by the Lac de Gras area, NWT), (3) prior diamond indicator sampling by industry and government has yielded many high quality diamond indicator minerals in at least three prominent trends on the property, such as angular olivine, chromites with favourable diamond inclusion chemistry, and perioditic and eclogitic garnets and pyroxenes, (4) diamond indicator minerals recovered from local bedrock sources indicate that there are possibly two ages of kimberlitic volcanism evident including intrusions at about 100 Ma and at about 70 Ma, (5) prior airborne geophysical surveys indicate the presence of numerous magnetic targets, and (6) the area is underlain predominantly by Lower Cretaceous to Tertiary sedimentary rocks similar in age and setting to that which exists at Fort a La Corne, Saskatchewan and the Buffalo Head Hills and Mountain Lake, Alberta. At present, the company is reviewing the diamond indicator data in conjunction with the existing geophysical data including both airborne geophysics and seismic profile data, in order to prioritize targets on Hawkeye's Front Range property. Perhaps the single most important tool for finding kimberlites to date in the Buffalo Head Hills area has been the correlation of magnetic data with seismic data. Trade seismic data is available for the Front Range property and will have to be purchased and reprocessed in order to evaluate the existing geophysical targets. Hawkeye expects to release the results of this work by early to middle summer. Several of the properties are in areas of moderate topographic relief and are amenable to focused fieldwork, including diamond indicator sampling and ground geophysical surveys, followed by a late summer or early winter drilling program.
