Call it  in  CategoryController.php   there  you  have  the  possibility  to  send  the  variable  to  smarty.

I just tried, same problem.

In CategoryController.php :

public static function getMinPriceValue($id_product)
{
	$reductions = DB::getInstance()->ExecuteS('
		SELECT price
		FROM `'._DB_PREFIX_.'specific_price`
        WHERE id_product = '.$id_product.'');
    
        return $reductions;
}

And in templates\catalog\_partials\miniatures\product.tpl :

{$reductions}

Error : Notice: Undefined index: reductions
