Closest match with these salts; it can't reach Mg 6.3 mg/L vs 49, HCO3 1798.3 mg/L vs 2075 exactly.
Chateldon is sparkling - the salts give you its minerals; carbonate the water yourself (e.g. with a soda maker) for the fizz.
Chalk (CaCO₃) doesn't dissolve well directly in mash or sparge water without dissolved CO₂ - slurry it in carbonated water (e.g. sparkling water) before adding it, rather than mixing it into still water or sprinkling it in dry, or the calculated amount may not fully dissolve.

Ca/Mg/Na/HCO3 from h2omatch.com's database; sulfate/chloride researched (confidence: Medium-High). Geochemical database profile has very close Na/Mg/HCO3 values but somewhat higher calcium than the file; SO4 20 and Cl 7 mg/L used with medium-high confidence.
