French term or phrase: teneur métrique
In a report of the geological survey of a potential area for gold-digging:

« malheureusement le programme de [method used] réalisé au [places where exploratory drilling took place] n’a révélé que des teneurs métriques. »

Obviously, they are talking about the gold content of the samples; and likewise, they are clearly disappointed that the content was too low to be worthwhile; but I am intrigued by this use of 'métrique', which I've not previously encountered.

Explanation:
/ gold concentrations with dimensions in the range of metres

Please note the low confidence level and feel freet to mark me down, but Tony has helped me out in the past and deserves input from myself.

agree  Mark Nathan: This is what I meant by in comparison to décimétrique, plurimétrique, i.e. across greater ranges

disagree  Daryo: you can't guess the exact meaning of technical terms just from general purpose dictionaries - almost never works. You need samples in the right context.

teneurs métriques
concentrations [measured] by one metre [thick] layers / at every metre / at one-metre intervals


Explanation:
The plural matters - there are always more than one "teneur métrique".

n’a révélé que des teneurs métriques
=>
the "sampling" of the measured variable ("teneur de chacun des minéraux valorisables" - here the content of gold) was done at regular intervals of 1 metre along a vertical line.

You could see " teneurs métriques" as an abbreviation for:

concentrations "mesurées par couches horizontales de 1 mètre d'épaisseur"

IOW the "method used" gives only values at 1 m intervals for the "gold content" instead of a continuous curve or at least measurements with finer granularity that would have been far more "informative" i.e. would have given a more accurate estimate of the "exploitable deposits".

CL5 about the meaning, OTOH not sure what would be the correct technical term in EN.

Possibly "at one-metre intervals"? Probably something shorter.


see

on top of page 53

Sondage S1 (too complicated to copy) where the concentrations are measured by layers/horizontal slices 1 meter thick

page 54:

A. Détermination de la teneur moyenne du concentré sur le profil

Le traitement des échantillons de sable permet d’obtenir la teneur en concentré contenu dans chaque passe métrique de chaque sondage du profil.

Ces teneurs seront reportées à leur place correspondante et inscrites sur un profil à l’échelle adéquate * s’inspirant du croquis ci-dessous:

(see the drawing at the bottom of page 54)


page 55:

1) Sur le sondage SI, on n arrête la profondeur du profil à 5 m, parce que les 2 m sous jacents ne présentent que des teneurs métriques en ML. inférieures à la teneur de coupure choisie de 5 % :
de 5 à 6 m : 2,40 %,
de 6 à 7m : 0,27 %. 2)

Sur le sondage S2, on remarquera que la tranche métrique comprise entre 1 et 2m de profondeur, présente une teneur inférieure à S 96 (3,10 96), mais elle est encadrée par des tranches métriques dont les teneurs sont supérieures à 5% :
— de Ø à 1m: l0, 03 %,
— de 2 à 3 m: 28,30%, etc. *
Ces lignes de sondages pourront être grossièrement relevées au clisimètre sur le terrain et leur profil reporté sur graphique; dans la majorité des cas et pour la commodité des présentations, les échelles de longueur ne seront pas les mêmes que celles des hauteurs. II est évident que lors de l’exploitation de ce panneau, on enlèvera toute la couche minéralisée jusqu’à 5,50 m qui restera payante; une strate de 1 m d’épaisseur à une teneur inférieure à celle de coupure ne fera pas chuter de beaucoup la teneur moyenne sur le profil qui sera de l’ordre de 13,99 %. On incorporera donc la tranche de 1 à 2m à 3,10 % dans les calculs.

3) Sur le sondage S3, la tranche comprise entre 5 et 6 m présente une teneur de 5,10 % (supérieure à la teneur de coupure 5 %), mais elle est séparée des niveaux supérieurs minéralisés, par 2 m d’une couche qui présente des teneurs inférieures à 5 % , respectivement — de 3 à 4 m: 0,05 %, — de 4 à 5 m: 0,20%. Il ne serait pas payant d’extraire ces deux mètres à teneurs infra économiques pour atteindre la couche comprise entre 5 et 6m; on arrêtera donc la tranche exploitable à la profondeur de 3 m.

more precisely the "teneur / concentration" of the payload / the valuable material was measured by finding the average value for segments 1 metre high / thick - without knowing the distribution of the "teneur" within the one metre layer. The author(s) would have preferred knowing the average "teneur" by segments of half-meter thickness, or maybe even more detailed, so it's "ONLY every meter" (le programme ... n’a révélé QUE des teneurs métriques)

« malheureusement le programme de [method used] réalisé au [places where exploratory drilling took place] n’a révélé que des teneurs métriques. »
=
the method used for prospecting .... has yielded data only showing [average] values for one meter layers / segments. (implicitly: not more precise / not more granulated than that)

I still don't see how this should be disappointing though:)

Asker: You have exactly understood my problem! Not metric tonnes, I don't think — here they are talking in ppb or g/tonne...

disagree  Daryo: can't be - the ST clearly states that "métrique" is a adjective qualifying "teneurs" - a ratio, not an absolute value, as would be weight just on its own.

Asker: Thanks, W/A! (and for correcting the language pair for me!) This is exactly similar to my context — and yes, I'm wondering if Suzie isn't maybe right and this is in fact a typo — my entire document is African FR and full of sometimes hilarious mistakes — like the 'béchique' I had the other day (instead of bréchique'!)

agree  Daryo: good reference - next step is to extract the useful information from it.

La métrique est ce qui permet de déterminer la distance entre deux points, elle représente en quelque sorte l'étalon infinitésimal d'un espace

et donc des teneurs infimes à cet endroit
