Kwekwe block 4

A four-peg block of about 1,560 ha, roughly 7.6 km east-west, sitting ~10 km north of Kwekwe block 2. The supplied corner order was self-intersecting, so the boundary shown is the polar-ordered footprint of the four pegs. This is exploration-scale ground, ~50 times the size of a standard 30 ha claim, so whole-block statistics average over very different ground and the useful output is where inside it to focus. 101 known gold mines fall within 40 km. This is a where-to-walk assessment on free satellite data, not a claim that gold is present.

Background overall, with one clear pocket worth the visit. Whole-block the fused model reads a median P(gold) of 0.238, the 34th percentile of the local background, in the same range as your other Kwekwe blocks. But all six of the block's top spots (P(gold) 0.62–0.71) fall in a single ~1.5 km pocket in the west-central interior, around 784700–786000 E / 7921300–7922700 N (UTM 35S). Start at 784673 E / 7922262 N (rank 1, P 0.71), then 785143 E / 7922672 N (P 0.69); the remaining four sit within ~1.3 km south-east of those two. If this block gets ground time, it should all go to that pocket first; the eastern and western thirds read as plain country rock.

The terrain arm supports the same read: the block sits at the 73rd percentile of the terrain signature of 64 known gold mines within 25 km (LOO AUC 0.935), and lineament density peaks in the north-west quadrant (70th percentile, dominant trend 030–045°), overlapping the pocket.

The best-ground spots (UTM 35S). All six fall in the same west-central pocket:

The five checks behind that

Each is scored over the block against the ground immediately around it.

Check This block What it means
Regional P(gold) 0.238 whole-block (34th percentile); pocket spots 0.62–0.71 background-level overall, which is expected when averaging 1,560 ha; the west-central pocket is the sole above-average patch and the only ground the model argues for
Terrain match 73rd percentile the block leans toward the terrain signature of 64 known gold mines within 25 km (LOO AUC 0.935, spatial CV at 8 km holdout 0.852)
Structure / lineaments 62nd percentile; NW quadrant 70th slightly elevated, peaking in the north-west quadrant that overlaps the pocket; dominant trend 030–045°; roads and field edges are the dominant false positive in cultivated ground (~6% of the block is vegetated/farmed)
Red-oxide (ferric) 46th percentile background; no surface oxide anomaly at block scale
ASTER alteration (SWIR) Al-OH 52nd, carbonate/Mg-OH 57th, chlorite 44th percentile archive 2004 scene, 0% cloud. Flat, and the decisive check is the 62 local mines on this scene: they carry no alteration signal beyond chance (separability +0.06 sigma), so ASTER has no discriminating power in this district

Compared to your other ground

Same estimate, run over each site:

Site P(gold) median Percentile vs local background
Belingwe-West 0.394 n/a
Silobela site 2 window (~1 g/t assays) 0.359 71st
Silobela block 3 0.346 69th
Kwekwe block 3 0.285 36th
Kwekwe block 2 0.254 45th
Kwekwe block 4 (this), whole block 0.238 34th
Kwekwe block 4 (this), pocket spots 0.62–0.71 n/a
Kwekwe block 1 0.129 8th

Read together with Silobela block 3, assessed the same day: if the choice is where to spend pegging money and ground time first, Silobela block 3 is the stronger and far cheaper test (29 ha at the 69th percentile, with the top Silobela spot on it). This block's case rests on one pocket; it earns a reconnaissance visit to that pocket before any commitment to the full 1,560 ha.

Data used

The P(gold) grid is 10 m (~0.01 ha cells), so it pins the pocket to walk, but it reads surface geology. It tells you where to look, not where a vein is.
