If you didnt see this in the other thread, this is from the drills earlier in the decade by LD.
Should have drilled it . . glad they didnt . . here we are . . TORONTO, ONTARIO--(Marketwired - Sept. 11, 2013) -Lago Dourado Minerals Ltd. (TSX VENTURE:LDM), (the "Company") today announces exploration updates on its Juruena project and its new Novo Astro target, a prolific set of artisanal workings positioned 28km along trend from Juruena.
Novo Astro -Over the last 12 months the Company has been steadily advancing the Novo Astro target, a prolific set of artisanal workings positioned 28km southeast and along trend from Juruena. Novo Astro is interpreted to be a classical lode-style structural system with gold hosted within intensely formed shear zones and sheeted veins. The mineralized system is large, based on a contiguous gold-in-soil anomaly of 2km by 2km, and hosts high-grade gold zones, based on assay values of rock chip samples (13 samples returned values greater than 10 g/t Au with one sample returning 263.8 g/t Au - see table below and Figures 2, 3 and 4 for further details). Novo Astro has not been previously drill tested. Moving forward, the Company will evaluate further investment at Novo Astro in the context of the market environment.

Novo Astro as a distinct magnetic low some 3km by 3km in dimension within highly varied granitic host rocks. Six principal gold-in-soil anomalies extending up to 2 km long have been identified within the main central gold-in-soil anomaly. Immediately south of the gold-in-soil anomaly and artisanal workings is an interpreted large and well defined magmatic heat source (based on geological mapping and a coherent Cu-Mo-Bi-W soil anomaly). The rare presence of Chromium with some of the gold bearing quartz veins suggest the mineralized system is associated with major deep tapping structures and intense ductile deformation thus enhancing the gold bearing potential of the Novo Astro system.
Mineralisation at Novo Astro is predominantly gold only, hosted within high-grade sub-meter and 1-5m wide shear zones. Shear zones range from steep to flat lying which may result in the stacking and thickening of mineralization. The majority of the gold trends are orientated west-northwest which corresponds to the dominant regional structural direction known to host gold elsewhere in the Alta Floresta gold belt.
