windermere drilling

It is interesting to see that last years results on the Gillian drill were released less than a month after they'd announced they'd started.

So maybe only another 3 weeks until results for Windermere maybe known and released to the market.

Here is the excerpt from John Sainsbury on Windermere from the website :

The Windermere skarn is a series of north south (mag) trending ironstone lenses and located 20 kilometres north east of Mt Garnet. The Deadmans Gully is an offset extension of the southern extent of the skarn. Strike length is 2.5 kilometres. The Deadmans Gully portion has been drilled by the Company. Historic costean digging and rock chip sampling exploration is all that has been undertaken on the main length of the skarn. The tin assay averages 0.6% Sn

The ironstone development within the Windermere skarns is similar to that at Gillian, with massive magnetite/haematite outcrop exposed at surface. The skarn trench exposures are of 4-8 metres width and dipping steeply to the east. Limestone/marble lenses outcrop along strike from some ironstone lenses and indicate not all limestone has been converted to skarn. The surrounding units are sandstones and siltones of the Chillagoe Formation. The nearest outcropping granite to the skarn is 200 metres to the west.

As with the Gillian skarn, the Windermere skarn represents alteration and change of precusor limestone units by a granite derived fluid. Based on outcrop, the granite is not in contact with the limestone and is at least 200 metres across strike from the limestone. As a result, the granite fluids need fracture access from granite to limestone. A distance between granite and skarn replaced limestone of 200 metres is known, with the example of the Moina tin skarn in Tasmania having a separation of at least 200 metres across strike between granite and skarn.

The Company 2008 airborne magnetic survey confirmed the outcropping disrupted nature to magnetite formation. A series of elongated magnetic bulleyes overlay outcropping ironstones.

The Windermere precusor limestone is a remnant disrupted portion of the Chillagoe Formation. The north south trend represented original strike length. The several lenses of ironstone likely represent original limestone lenses.

Depth extent of skarn development is unknown but there is nothing to suggest that a 200 metre depth could not be found.
