New Discovery Resulting in a 20KM Mineralized Gold Belt
Hey Mike- Welcome to Agoracom and our GNH discussion group. I think when Brattymack was referring to his site visit he was thinking of the beautiful piece of gold-bearing quarz in diorite drill core he held in his hands. As you will see from the exerpts below, that is where the majority of the gold iis found in the Timmins deposit and that is why they are drilling deep. Remember also that the high grade core you referred to in your first post came from > 200 m below the surface. I have included some basic information from our technical report below describing how the host rocks for the quartz deposits were thought to be formed in sea bed sediments millenia before the glaciers arrived. There is also included a statement from the report regarding the contribution of glacial till to the regional geology just so you know the company is aware of the glacial deposits in the region but has chosen to focus its exploration elsewhere.
Please do not make the mistake of confusing the rationale for our drill program with those of Bowmore and Uragold - the nature of the geological settings are very different.
What happened before the glaciers arrived...
Intermediate to basic igneous rocks have invaded parts of the volcanoclastic and sedimentary
sequences. These rocks are described as sills of albite diorite and gabbro, and it is suggested they
were injected into unconsolidated ocean-bottom sediments. They tend to follow the strike of the
Magog rocks and are notably elongated in the grain of the country.
In the immediate area of the Bellechasse-Timmins deposit the diorites give the appearance of rather
normal intrusive igneous rocks, and it is difficult to support a more exotic origin. The intrusives tend
to follow the bedding of the volcanoclastics (largely water-lain tuffs) in the area drilled to date. The
diorites show cross-cutting relationships with the tuffs, chill margins, inclusions of undeformed
tuffs, roof pendants, assimilation, and magmatic stoping. There is no evidence of violent reaction of
the magma with water-saturated unconsolidated sediments.
The diorites are the dominant host of the gold-bearing quartz-filled breccias that are being explored.
However, gold-bearing quartz-filled structures exist in the volcanoclastics that host the diorite
intrusives, and appear to be related to mineralizing activity originating within the diorites. (from GNH 43-101 Technical report- page 25)
Steatement regarding glacial till...
Bedrock exposure is poor particularly in the valleys, although the ridges often show bald outcrop,
and the up-ice slopes are generally not deeply covered by glacial deposits. In the valleys the tills and
related unconsolidated deposits are often tens of meters thick and frequently contain large boulders,
often of intrusive rock. Tills consists of clay, sand, gravel and boulders. Glacial-fluvial deposits and
tills reworked by recent streams are common in the valleys along the larger streams. Occasionally
small eskers and outwash deposits are encountered. (from GNH 43-101 Technical report-page 20 )
